As your engine ages, seals deteriorate, oil burn-off increases and sludge can build up, which can all result in a decrease in engine performance and, ultimately, reduce engine life. Mobil 1 High Mileage 10W-40 fully synthetic motor oil is designed to maximize engine performance and help extend engine life.
Mobil 1 High Mileage motor oil is designed especially for engines where conventional oil has been used, and where these conditions have been experienced:
Severe Service
Extended Oil Drains
Poor Maintenance
Multiple Owners
For engines where heavy deposits and sludging exist, we recommend initial oil change intervals of 3,000 miles as cleanup progresses.
Mobil 1 High Mileage 10W-40 is designed for higher mileage vehicles and provides the following benefits:
Extra anti-wear additive helps protect critical engine parts.
Reduces the sludge and deposits conventional oils can leave behind.
Contains a special seal conditioner to help recondition seals and prevent leaks.
Higher viscosity formula helps reduce oil burn-off and leakage.
