Mobil 1™ High Mileage

Provides unsurpassed wear protection for vehicles with more than 75,000 miles*

Mobil 1 High Mileage oils are designed to help extend engine life and prevent engine oil leaks. To help prevent wear in higher mileage engines, this advanced, fully synthetic high mileage oil features:

If your engine contains excessive sludge deposits due to less-than-adequate maintenance practices, Mobil 1 High Mileage synthetic motor oil can help reduce this sludge. For severe cases of engine sludge, short oil change intervals (3,000-5,000 miles) are recommended for the first two or three oil changes as the sludge reduction takes place. (In cases of engine damage that may have resulted from poor maintenance, even Mobil 1™ motor oil cannot remedy years of neglect.)

Still have additional questions, such as, “Should I use high mileage oil?” or, “Is high mileage oil worth it?” Learn more about the benefits of high mileage oils in our Car Maintenance archives. And please reference our Mobil 1™ Product Guide for a quick look at the boosted levels of key anti-wear additive in our high mileage motor oils.

*According to the industry-accepted Sequence IVA engine wear test.
