FAQs for Mobil 1™ Annual Protection

Mobil 1™ Annual Protection motor oil is for both new cars and older cars. Available in 0W‐20, 5W‐20 and 5W‐30 viscosities, Mobil 1 Annual Protection oils are recommended for all types of modern vehicles, including high‐performance, turbocharged, supercharged, multi‐valve and fuel‐injected engines that are found in passenger cars, SUVs, light vans and light-duty trucks. Mobil 1 Annual Protection motor oil offers guaranteed engine protection for 20,000 miles or one full year between oil changes, whichever comes first.
Mobil 1™ Annual Protection motor oil has been tested and proven to provide outstanding performance and engine protection for one year or 20,000 miles, whichever comes first. However, to help ensure continuation of your manufacturer’s new car warranty while using Mobil 1 Annual Protection motor oil, we recommend the following:
  • If your vehicle is covered by a warranty, follow the vehicle’s oil life monitor or the oil change interval recommended in your owner’s manual to avoid a disruption in your vehicle warranty.
  • Follow the oil change interval in your owner’s manual if your vehicle is operated in any of these severe service conditions: racing or commercial applications including taxis, limousines, etc.; frequent towing or hauling; extremely dusty or dirty conditions; or under excessive idling conditions.
  1. Check to see if your vehicle is a good candidate for extended oil change intervals by considering the following:
    1. If your vehicle is covered by a new car warranty, follow the oil change interval recommended in your owner’s manual to avoid a disruption in your warranty.
    2. Follow the oil change interval in your owner’s manual if your vehicle is operated in any of the following severe service conditions: racing or commercial applications including taxis, limousines, etc.; frequent towing or hauling; extremely dusty or dirty conditions; or under excessive idling conditions.
  2. Check your oil level frequently to ensure it’s at the proper level. Add oil if necessary.
  3. The Mobil 1™ Extended Performance Oil Filter is recommended for extended oil change intervals and meets the requirements of the Mobil 1™ Annual Protection limited warranty. When extending oil change intervals beyond your car manufacturer’s recommendation, always use a high‐quality oil filter designed for your intended oil change interval.
  4. Regular vehicle maintenance is important to keep your vehicle performing safely and reliably.
  5. Learn more about how you can be protected by the Mobil 1 Annual Protection limited warranty.

Mobil 1™ Annual Protection motor oil has been tested and proven to protect for one full year or 20,000 miles between changes, whichever comes first. However, we recommend changing your oil based on your owner’s manual recommendation or when your change oil indicator light comes on:

  1. If your vehicle is under a manufacturer’s warranty, follow the recommendation in the owner’s manual or oil life monitor.
  2. If your vehicle is operated in severe service conditions: racing or commercial applications including taxis, limousines, etc.; frequent towing or hauling; extremely dusty or dirty conditions; or under excessive idling conditions, follow the severe service recommendation in your owner’s manual.

The “Change Oil” light is programmed by auto manufacturers based on the minimum acceptable oil quality required for your vehicle’s engine. The “Change Oil” light cannot detect or adjust its program when you use Mobil 1 Annual Protection, a motor oil formulated and proven to protect beyond auto manufacturers’ recommended oil change intervals. As a result, the “Change Oil” light will likely go on well before 20,000 miles or one year when using Mobil 1 Annual Protection oil. When extending oil change intervals, it is extremely important that you check your oil level frequently and add oil when needed, at least once per month or every 1,000 miles, whichever comes first.

Most change oil lights are programmed by car manufacturers based on a specified number of miles or an algorithm that estimates when your engine is ready for an oil change. In either case, it is very unlikely that you will be able to change this program.

However, you can establish your own system for tracking when you have reached one year or 20,000 miles, whichever comes first. Placing a static cling oil change sticker on your windshield, indicating both the date of your last oil change and the mileage, can help you keep track of when your next oil change is due. Also, using one of your vehicle’s tripometers to track the mileage since your last oil change can be helpful.

If you adopt your own oil change tracking system, you may want to consider resetting your change oil light to avoid confusion. We suggest checking your owner’s manual or contacting your car dealer/installer to learn how to reset your change oil light.

All engines burn oil. The amount of oil that your car’s engine burns is primarily a function of the engine design. This means that even if you use an extended life motor oil, such as Mobil 1™ Annual Protection, your engine will still burn oil over time.

To protect your engine during extended oil change intervals, it is extremely important that you check your oil level frequently and add oil when needed, at least once per month or every 1,000 miles, whichever comes first. Remember, when your engine operates on a low oil level, a smaller amount of oil than the engine is designed to run on must work harder to adequately lubricate your engine.

Regular maintenance cannot be ignored while using Mobil 1 Annual Protection motor oil, including checking your vehicle’s oil level regularly and adding oil if necessary. While Mobil 1 Annual Protection motor oil provides excellent protection against oil burn‐off, your vehicle’s oil consumption is primarily a function of the engine design. Some engines use more oil than other engines. Check your engine oil level regularly to ensure that your engine has the proper amount and add if necessary.

A best practice is to use the same oil (brand/type/viscosity) for top‐offs as what is currently in your engine. While Mobil 1 Annual Protection motor oil is compatible with other oils, mixing oils may reduce the effectiveness of Mobil 1 Annual Protection motor oil and is not recommended.

Mobil 1 Annual Protection motor oil is a breakthrough in synthetics technology, an ultimate full synthetic formulation, designed to provide our longest‐lasting, guaranteed* engine protection. Mobil 1 Annual Protection motor oil helps extend oil life, delivering proven engine protection for one year or 20,000 miles between oil changes, whichever comes first. With Mobil 1 Annual Protection motor oil, you can keep your engine running like new and have the convenience of longer time between oil changes. Learn about Mobil 1 Annual Protection motor oil’s proof of performance testing and its engine guarantee.

*Please follow the recommendations in your owner's manual while your car is under warranty.

All viscosities of Mobil 1 Annual Protection motor oil meet or exceed the requirements of the latest industry specifications (ILSAC GF‐5, API SN Plus). Additionally, Mobil 1 Annual Protection motor oil is approved by General Motors dexos1™. For a full list of industry specifications and car builder approvals, see the Mobil 1 Annual Protection product data sheet.

Switching from conventional motor oil to Mobil 1 Annual Protection motor oil is perfectly acceptable. Mobil 1 Annual Protection motor oil is compatible with conventional oils, oils for high mileage vehicles, synthetic blends and other full synthetic oils.

Engine flushing is not required. However if your vehicle has a higher‐mileage engine that has never used synthetic motor oil, or one that has been poorly maintained with infrequent oil changes, we recommend easing into extended drains to allow Mobil 1 Annual Protection to clean up the engine. In these cases you should still follow the same basic oil‐change procedures (drain the old oil, remove the old oil filter, put in new Mobil 1 Annual Protection motor oil and put on a new oil filter). Follow your OEM’s recommended maintenance practices regarding oil changes, but you should follow more frequent (one or two non‐extended drain) oil changes when first switching to synthetic oil. The reasoning behind these shortened oil drain intervals is that a high‐mileage engine, or one that has had a lack of maintenance (including infrequent oil changes), will likely have a considerable buildup of sludge and deposits. Mobil 1 Annual Protection motor oil will help clean the engine as you drive, but it will have to work much harder in a very “dirty” engine and so it is best to change the oil more frequently for those first several thousand miles. After that, you can rest assured that Mobil 1 synthetic oil is continuing to keep your engine running clean and well lubricated for mile after mile.

The Mobil 1 Extended Performance Oil Filter is recommended for extended oil change intervals and meets the requirements of the Mobil 1 Annual Protection limited warranty. However, use of the Mobil 1 Extended Performance Oil Filter is not a requirement of the Mobil 1 Annual Protection limited warranty. When extending oil change intervals beyond your car manufacturer’s recommendation, use a high‐quality oil filter designed for your intended oil change interval.

We recommend that you change your oil filter at the same time you change your oil, and that you use an oil filter that offers protection for your intended oil change interval. Mobil 1™ Extended Performance Oil Filters provide guaranteed* protection for one year or 20,000 miles, whichever comes first. Therefore, these long‐life performance oil filters are an excellent choice when using Mobil 1 Annual Protection motor oil, which also offers guaranteed* protection for one year or 20,000 miles, whichever comes first.

*Please follow the recommendations in your owner's manual while your car is under warranty.

In other words, if you drive under normal conditions and use Mobil 1™ Extended Performance synthetic oil in your vehicle, the oil is guaranteed to protect your engine for 15,000 miles. We also recommend that drivers consult their owner’s manual while their vehicle is under warranty, and follow the guidelines set forth there. Additionally, we recommend that if consumers drive routinely in severe conditions that they follow the oil change interval recommended in their owner's manual for severe conditions. We define "severe conditions" as:

  • Racing or commercial applications
  • Frequent towing or hauling
  • Extremely dusty or dirty conditions

FAQs for Mobil 1™

First, the performance of Mobil 1™ line of motor oils is more robust, especially in terms of low temperature pumping and flow. High‐temperature stability leading to protection against deposits is also superior. These attributes translate into less engine wear, which helps keep your engine running like new, and obtain long engine life. Synthetic blend oils lack the high level of performance of synthetic motor oils in the areas of low‐temperature performance and high‐temperature oxidation stability. The base stocks used in Mobil Super™, one of our synthetic blend motor oils, are of a high quality, but those used in Mobil 1 fully synthetic oils are better.

Yes. Mobil 1 is fully compatible with conventional motor oils, semi‐synthetic motor oils and other synthetic motor oils, should it be necessary to mix them. But the superior performance of Mobil 1 will be reduced by diluting it.
With the exception of the Mazda rotary engine (Mazda does not recommend any synthetic oils), Mobil 1 will not void new‐car warranties where an American Petroleum Institute (API) certified oil is recommended. Mobil 1 meets or exceeds API and International Lubricant Standardization and Approval Committee (ILSAC) motor oil service requirements of all new‐car manufacturers, both import and domestic. If in doubt, always check your vehicle owner's manual or contact the vehicle manufacturer.

Many kinds of driving conditions qualify your vehicle for severe service oil change intervals, and Mobil 1 is ideal for this service. Severe service conditions can include, among other things:

  • Trips of less than 10 miles
  • Driving in cold weather
  • Idling for extended periods
  • Stop‐and‐go traffic
  • Pulling trailers/carrying heavy loads
  • Driving in dusty conditions

Under both normal and severe service conditions, Mobil 1 is engineered to provide performance reserves in the areas of sludge prevention, piston cleanliness, wear protection and high‐temperature durability.

Oil change intervals can be as short as 3,000 miles or as long as 15,000 miles on some new cars. We recommend that you follow the oil and filter change frequencies shown in your owner's manual, especially during the warranty period. With the high‐performance reserves of Mobil 1, you can have the confidence to go the full mileage or time frame recommended by the vehicle manufacturer. Mobil 1 is especially suitable for the latest vehicles with extended drain intervals or vehicles with oil monitoring systems that vary oil drain intervals. To fulfill the requirements of the Mobil 1 limited warranty, Mobil 1 motor oil must be changed at least every 10,000 miles or your vehicle’s OEM recommended oil change interval, whichever is longer.

ExxonMobil does not recommend it. According to the American Petroleum Institute (API) and Alliance of Automobile Manufacturers (AAM), "certified oils eliminate the need for supplemental engine oil additives." In fact, the use of any oil supplement is not recommended by car manufacturers and may void a warranty.

Yes, if the small engines are four‐cycle engines that call for detergent‐type motor oil. This type of engine has a separate crankcase for motor oil – it's not mixed with gasoline.

You should follow the same environmentally sound procedures that you do with conventional motor oil. The U.S. Environmental Protection Agency's (EPA) guidelines for disposal include:

  • Do not dump used motor oil in the trash.
  • Do not pour it on the ground or down the sewer or storm drain.
  • Place the used motor oil in a closed container.
  • Take it to a service station or a collection location that recycles used motor oil.
  • Do not burn the used motor oil in a space heater.
  • Do not mix motor oil with other substances, such as gasoline or antifreeze.

Many Exxon and Mobil service stations will take used motor oil from do‐it‐yourselfers and will follow EPA‐approved recycling practices. Please note that it is acceptable to mix used Mobil 1 with used conventional oil. In short, Mobil 1 should be disposed of in the same manner as used conventional motor oil.

FAQs for High mileage oils

Yes. High mileage engines – those with more than 75,000 miles – face a number of potential problems that high mileage oil is specifically formulated to address. Some high mileage motor oils, such as Mobil 1™ Extended Performance High Mileage, Mobil 1™ High Mileage and Mobil Super™ High Mileage, contain engine oil additives and conditioners that help to combat leaks, sludge and general wear and tear. The Mobil 1 lineup of high mileage oils, in addition to providing unsurpassed wear protection, is formulated with a higher base oil viscosity to help reduce leaks and provide better high temperature protection. High mileage oil helps extend engine life through these additives and conditioners, which make using a high mileage oil an important investment in your vehicle.

Wear protection starts with reducing metal‐to‐metal contact. According to the industry‐accepted Sequence IVA engine wear test, the Mobil 1™ family of motor oils offers unsurpassed wear protection. Mobil 1 Extended Performance High Mileage and Mobil 1 High Mileage oils are part of our line of advanced full synthetic motor oils using the latest in additive and base oil technologies. In addition, Mobil 1 Extended Performance High Mileage oils are the only high mileage motor oils that guarantee 15,000 miles of protection.

No, we chose not to, to specifically address the protection needs of older vehicles with more than 75,000 miles. The increased base oil viscosity of Mobil 1 High Mileage oils helps reduce wear and provide better high temperature protection for vehicles with over 75,000 miles. Mobil 1 High Mileage oils do meet the latest API industry requirement of API SN Plus. Mobil 1 Extended Performance High Mileage and Mobil Super™ High Mileage oils are GF‐5 products.

Mobil 1™ Extended Performance High Mileage and Mobil 1™ High Mileage motor oils are designed for high mileage vehicles that have been using conventional motor oils. It's true that most vehicles with more than 75,000 miles should be in excellent condition if Mobil 1 oils have been used regularly, and would not require some of the Mobil 1 Extended Performance High Mileage and Mobil 1 High Mileage benefits. However, many cars on the road today do not use synthetic oils, so we developed our high mileage oils specifically for these cars that would benefit from switching off conventional oil.

If your vehicle has been maintained well, Mobil Super™ High Mileage represents an excellent choice. However, if you believe your engine may have sludge through less‐than‐adequate maintenance practices, Mobil 1 High Mileage may be the more suitable selection. Mobil 1™ High Mileage helps reduce the sludge that other oils can leave behind, which can result in extended engine life. For severe cases where sludge and other heavy deposits are present, shorter oil change intervals of 3,000 miles are recommended as cleanup proceeds.

FAQs for Mobil 1™ Advanced Fuel Economy

Mobil 1™ Advanced Fuel Economy oils are fully synthetic motor oils engineered to deliver outstanding engine protection and fuel economy benefits. The low‐viscosity, advanced full synthetic formulation can help to increase engine efficiency and improve fuel economy versus higher viscosity oils. Mobil 1 Advanced Fuel Economy oils outperform conventional oils and meet or exceed the latest industry standards.

Not only does this help reduce wear on engine parts but it also reduces the demands on your starter and battery. Mobil 1™ 0W‐20 and Mobil 1™ 0W‐30 are certified as "Resource Conserving" by both the International Lubricant Standardization and Approval Committee (ILSAC) and the American Petroleum Institute (API).

Mobil 1 0W‐20 and 0W‐30 Advanced Fuel Economy synthetic motor oils deliver up to 2 percent fuel economy improvement* and can save drivers more than $400 on gasoline over the life of their vehicles. That's a savings of about six cents per gallon of fuel. A typical passenger car with a 20‐gallon gas tank can go up to nine more miles on a tank of gas when using Mobil 1™ Advanced Fuel Economy in either 0W-20 or 0W-30. That equates to up to 250 more miles per year under typical conditions.

*Fuel economy improvement is based on a comparison versus those viscosity grades most commonly used and a potential 2 percent fuel economy improvement. Actual savings are dependent upon vehicle/engine type, outside temperature, driving conditions and your current engine oil viscosity. Savings estimates are based on a gasoline cost of $3 per gallon, average fuel economy of 22.5 miles per gallon, annual mileage of 12,500 and lifetime mileage of 150,000.

A potential 0.2‐2.3% fuel economy improvement can be obtained by switching from higher viscosity oils to a 0W‐20 or 0W‐30 grade. Actual savings are dependent upon vehicle/engine type, outside temperature, driving conditions and your current engine oil viscosity. The higher your current viscosity, the greater the potential for savings.

Industry data confirms that lower viscosity motor oils, like the 0W‐20 and 0W‐30 viscosity grades offered as part of the Mobil 1™ Advanced Fuel Economy line, contribute to improved fuel economy over the life of the vehicle. However, fuel economy improvement can be influenced by many factors, including your vehicle/engine type, outside temperature, driving conditions, adjusting tire pressure and your current engine oil viscosity.

Mobil 1™ Advanced Fuel Economy motor oils are low‐viscosity, advanced full synthetic formulations that can help to increase engine efficiency and improve fuel economy.

Mobil 1™ 0W‐20 Advanced Fuel Economy  meets or exceeds many new car warranty requirements where SAE 0W‐20 or 5W‐20 oil is recommended.

FAQs for Motorcycle Oils

It's a little hard to generalize about the difference between Mobil 1 passenger‐car motor oils and Mobil 1™ motorcycle oils. That's because not all viscosities of Mobil 1 passenger‐car oils have the same levels of zinc and phosphorus, and there are even greater differences between the two Mobil 1 motorcycle oils.

  • In general, Mobil 1 motorcycle oils have additive packages formulated for use in both motorcycle engine and transmission operation.
  • For passenger vehicles, fuel economy and emission system protection are higher priorities. These require low phosphorus systems and the use of friction modifiers.
  • Motorcycle oils do not require friction modifiers for fuel economy and for better clutch friction less/no friction modifier is optimum.
  • Motorcycle oils allow the use of higher levels of anti‐wear additives such as ZDDP (phosphorous).

Plus there are the overall benefits of Mobil 1 synthetic oil compared to those of conventional motor oils, whether they be for passenger cars or motorcycles:

  • Superior long‐term engine protection
  • Superior high‐temperature stability
  • Excellent low‐temperature starting
  • Outstanding engine performance
  • Low volatility/low oil consumption

In addition to the overall benefits of high‐temperature stability and low volatility/low oil consumption, Mobil 1 synthetic motorcycle oils also offer superior anti‐corrosion performance compared to conventional motor oil, which is important in many parts of the country where bikes may sit in garages for several months of the year. Compared to conventional oils, Mobil 1 motorcycle oils provide superior wear and high‐temperature protection, and promote engine cleanliness and lower oil consumption. Once you get beyond these general advantages, you have to consider individual motorcycle oils to understand the benefits of each.

Mobil 1 Racing™ 4T 10W‐40 is designed for sport bikes. Most of these bikes have multi-cylinder/multivalve engines and use a common sump, which means the engine oil lubricates the engine, transmission and wet clutch. So unlike Mobil 1 for cars, Mobil 1 Racing 4T 10W‐40 motor oil has no friction modifiers, which could lead to clutch slippage. The motorcycle oil also has more phosphorus/zinc for enhanced wear protection at high engine speeds and high loads. In addition, Mobil 1 Racing 4T 10W‐40 has a high performance dispersant/detergent technology for better high‐temperature performance and engine cleanliness. Mobil 1 Racing 4T 10W‐40 is also offered in a different viscosity grade than Mobil 1 for passenger cars.

Mobil 1™ V‐Twin 20W‐50 fully synthetic motorcycle oil is designed for air‐cooled, large‐displacement bikes. Because of their design, these engines can generate very high localized oil temperatures and high overall bulk‐oil temperatures. A typical air‐cooled V‐twin's rear cylinder gets a lot hotter than the front cylinder – it's a matter of airflow. When it's hot out and you're stuck in traffic, the oil temperature in a bike climbs rapidly. Above about 250 degrees Fahrenheit, conventional motor oil is going to break down. Mobil 1 V‐Twin 20W‐50 fully synthetic motorcycle oil is good to above 300 degrees Fahrenheit. Like Mobil 1 Racing™ 4T 10W‐40, Mobil 1 V‐Twin motorcycle oil has high levels of phosphorus/zinc and the same high‐temperature detergent technology for superior wear protection and engine cleanliness, even at elevated oil temperatures. With Mobil 1 V‐Twin motorcycle oil, you can go the full length of the manufacturer's recommended oil change intervals with ease.

FAQs for Racing Oils

Mobil 1 Racing™ oils employ fully synthetic, latest generation, wide viscosity grade racing oil technology designed to help reduce engine friction and protect the engine under high output conditions in high operating temperatures. Mobil 1 Racing 0W‐50 motor oil offers boosted levels of anti‐wear protection (nominal zinc level of 1,850 ppm) for extra engine protection in highly loaded flat tappet engine designs.

Mobil 1 Racing™ oils offer high‐temperature protection at temperatures over 500 degrees Fahrenheit (260 degrees Celsius) and are suitable for temperature protection where supercharging and turbocharging is employed.

Oil drain intervals in racing conditions can vary widely. Depending on specific racing applications and conditions, intervals of 500 miles or more are attainable. When determining the correct interval at these extreme conditions, used oil quality should be monitored because each application and environment can be different.

There is no need to run a special break‐in oil if using Mobil 1™. Mobil 1 oil has a robust additive system that helps provide protection during break‐in as well as normal operation.

Mobil 1 Racing™ oils are not recommended for everyday general street use where vehicles use catalytic exhaust converters.

Mobil 1™ oils are compatible with most fuels; however, excess fuel dilution may require more frequent changes and used oil analysis for quality monitoring.

Mobil 1 15W‐50 is a higher viscosity oil that delivers a thick oil film for protection of high‐performance engines. Mobil 1 15W‐50 can be used and is recommended for both street and track use; however, Mobil 1 Racing™ oils are not recommended for general street use where vehicles use catalytic exhaust converters. Mobil 1 Racing™ 0W‐30 and Mobil 1 Racing™ 0W‐50 are lower viscosity oils designed to protect the engine under high output conditions in high operating temperatures. Additionally, Mobil 1 Racing oils offer boosted levels of anti‐wear protection (nominal zinc level of 1,850 ppm) for extra engine protection in highly loaded flat tappet engine designs like those used in the NASCAR® Sprint Cup series.

These oils are not recommended for wet clutch applications due to their high level of molybdenum.

Mobil 1 Racing oils are formulated with the same race-proven, fully synthetic technology used in racing applications around the world. However, typically, Mobil 1™ engineers tailor the racing oil technology based on the specifications required by specific teams and/or race applications.

Automotive street use oils that meet the latest industry standards are required to have a lower level of zinc and phosphorus anti‐wear chemistries than oils formulated years ago. The latest automotive street use engine oils are designed to be compatible with emission control equipment. Mobil 1 Racing oils are formulated with anti‐wear (zinc/phosphorus) chemistries at twice the level of automotive street oils to provide enhanced protection of highly loaded valve train systems found in some race engines. Based on the high level of anti‐wear chemistries, Mobil 1 Racing oils are not recommended for street use.

Mobil 1 Racing™ oils employ fully synthetic, latest generation, wide viscosity grade racing oil technology, designed to help reduce engine friction and protect the engine under high output conditions in high operating temperatures. Both Mobil 1 Racing™ 0W‐30 and Mobil 1 Racing™ 0W‐50 motor oils offer boosted levels of anti‐wear protection (nominal zinc level of 1,850 ppm) for extra engine protection in highly loaded flat tappet engine designs.
