FAQs

I am thinking about switching to a high mileage motor oil. Is high mileage oil worth it?

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.

What is the difference between Mobil 1™ Extended Performance High Mileage motor oil, Mobil 1™ High Mileage motor oil and other high mileage motor oils?

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 20,000 miles of protection.

I thought Mobil 1™, as a full synthetic oil, already provided the protection my high mileage car needs. Do I really need to switch off Mobil 1 to your high mileage products for my high mileage car?

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.

Rated 5 out of 5 by Toad from Unleashes the beast. As a farmer of 40 years, I’ve always used whatever oil the local Farmers Co-op sold. The longer I used the Coop oil the more my equipment seemed to be lacking performance and economy, not that it was a bad oil, it just lacks some luster. I switched to Mobil 1 recently and it was like all my equipment had unleashed its full potential. Amazing oil!

Rated 5 out of 5 by Nitro1 from I have been using mobil 1 for over 40 years and I’m a certified professional car mechanic and I have disassembled many car and truck engines and Mobil 1 has the lowest sludge build up that I have experienced ever, and that’s a value piece of mind that I’m willing to bet on, but it’s up to you to choose for yourself what kind of engine oil is best for you and your car, but I would bet on Mobil 1 anytime because I’ve had great success with this motor oil, but I do recommend 5W/30 in the winter and 5W/40 for the winter time, because when it’s very hot outside it makes you oil more thinner and during the winter months your oil gets thicker so that what I use with my cars. Thank you Mobil 1

Rated 5 out of 5 by Inft from 250k miles on this oil alone! No issues! I bought a 2014 Infiniti Q50 3.7 naturally aspirated in 2017 with 42k miles on it. I've been running Mobil 1 Avanced Full Synthetic with matching filter every oil change since I purchased this car. I started using extended performance high mileage as soon as i noticed it on the shelf. 274k miles later still running strong! No leaks, no smoke, no issues period. Best oil I've ever used. I use this oil in all of my vehicles and always will.

Rated 5 out of 5 by Sora from Won't use anything else but this! When I first got my car, it had 136k miles on it and no history of what was put in it. Immediately put this in, and I've had, for the past two years of owning the car, only used this and in between changes I've put NO oil in it! Same quart of oil is still sitting in the trunk since I bought the car. Doesn't leak, doesn't burn, runs great at 170k miles. Nice and smooth, and I get up to 15k miles out of each change. Comes out still with another few thousand left on the oil. I will use this oil on any car I own (correct weight, of course. Never stray from manufacturer recs!) and recommend this oil to everyone. I work at a parts store and regularly switch people over to this oil brand and line.
