Mobil 1™ High Mileage oils are designed to help maximize engine performance and extend the engine life of vehicles with over 75,000 miles.
Mobil 1 High Mileage is available in five viscosity grades 0W-20, 5W-20, 5W-30, 10W-30 and 10W-40.
Features and Benefits
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.
Mobil 1 High Mileage oils are designed to help extend engine life in high mileage engines. These advanced full synthetic motor oils feature:
A proprietary blend of high-performance synthetic base oils that deliver up to 500,000 miles of proven protection
Higher base oil viscosity to help reduce leaks and provide better high-temperature protection†
A boosted level of seal conditioner to protect engine seals because, over time, rubber seals can harden or shrink, resulting in oil leaks
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.)
