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 Anonymous from Happy engine =Happy ride I've been a mechanic my entire life and I'm 55 years old. Mobil 1 has always been the premium oil and used in engine's to sustain a long high mileage life. It outperforms my expectations and has been keeping my 2010 Ford Taurus with 183,720 mileage just purring like a new one.

Rated 5 out of 5 by ilyf2 from Oil I can depend on We have tried many types and brands of oil for our cars. But Mobil 1 is a good one with its triple action formula it’s an oil we can trust with our cars. I’m really pleased with the extended performance for high mileage cars(75,000+), and it’s fully synthetic.

Rated 5 out of 5 by janastnn from High quality oil Changed the oil on my Jeep Wrangler and it’s was a piece of cake. The oil was easy to pour and I believe it gave me a couple extra MPG. It’s high quality oil. I got this from Walmart, I was cheaper there then a auto parts place. I like it because it’s for high mileage motors and that’s what we mostly own.

Rated 5 out of 5 by kellies76 from Better gas.mileage? My husband changed the oil in my Honda. He used the Mobil 1 Extended Performance High Milage full synthetic Motor oil 5w 20. It seems to be running great since the oil change. I think it may even be getting better gas mileage. No problems thus far and we will be using it on the next oil change as well

Rated 5 out of 5 by brittanyh396 from Top notch performance Absolutely phenomenal! Mobil 1 motor oil had exceeded our expectations. We've been using it exclusively in our vehicles for a long while. The engine runs great and the protection from wear and tear has been top notch. The difference in the performance was noticeable from the start. The improved fuel efficiency has been a great feature and we have saved time and money by switching.

Rated 5 out of 5 by neliag1 from Great Oil This oil performs as expected. The packaging makes it easy to poor the oil into my car. It isn't that much more expensive than the oil we usually buy. I would buy this again.

Rated 5 out of 5 by Anonymous from Best Oil I feel safe using this Motor Oil from Mobil 1 foe my jeep because I know it will help it give me the performance I need to stay safe on the road with my family. I use the 5w-20 because it can handle cold weather better than the 5w-30 and the thickness is perfect for the emission compliance.
