Mobil 1 High Mileage oils are made with a proprietary blend of high performance synthetic basestocks fortified with an additive system designed especially for higher mileage vehicles. Mobil 1 High Mileage oils are especially recommended for high mileage vehicles even those that have used lower quality conventional oils. (Note 1)

Note 1 -- 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 (3000 - 5000 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.
