Outperforms our conventional and synthetic blend high mileage oils

Mobil 1 High Mileage 10W-40 motor oil provides excellent overall lubrication and wear protection, meets or exceeds the industry's toughest standards and outperforms our conventional and synthetic blend high mileage oils. The advanced full synthetic formula can also help:

  • Extend engine life
  • Clean up engine sludge with active cleaning agents
  • Prevent leaks with seal conditioner

*Protects for 10,000 miles or 1 year, whichever comes first. For more information, read our Mobil 1 limited warranty.
If your engine has excessive sludge deposits due to less-than-adequate maintenance practices, Mobil 1 High Mileage can help by reducing the sludge left behind in your engine. For severe cases of sludge, short oil change intervals (3,000-5,000 miles) are recommended for the first 2-3 oil changes as reduction of the sludge takes place. In cases of engine damage that may have resulted from poor maintenance, even Mobil 1 cannot remedy years of neglect.

 

FAQs

 

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 20,000 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.
