Mobil 1 Mobil 1™ High Mileage 5W-30 Quart Bottle (0.946 Liter)


Mobil 1™ High Mileage 5W-30

Helps extend engine life and prevent leaks in vehicles with more than 75,000 miles

Mobil 1 High Mileage oils are designed to help maximize engine performance and extend engine life in older vehicles.

These advanced full synthetic oils are made with a proprietary blend of high-performance synthetic base oils fortified with an additive system designed to help prevent leaks.

If your engine contains excessive sludge deposits due to less-than-adequate maintenance practices, Mobil 1 High Mileage oils can help by reducing this sludge. For severe cases of 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 cannot remedy years of neglect.)

Please reference our Mobil 1™ Product Guide for a quick look at specifications including zinc and phosphorus, as well as manufacturer approvals for Mobil 1 motor oils.
