Many newer vehicles recommend a 5W-30 engine oil viscosity and now you can continue using the viscosity recommended for your vehicle by the car builder as your vehicle ages.
Use Mobil 1 High Mileage 5W-30 for vehicles where a 5W-30 viscosity is recommended and the engine is in sound mechanical condition i.e., not burning oil. For vehicles where oil consumption is a problem, higher viscosity oils like Mobil 1 High Mileage 10W-30 or Mobil 1 High Mileage 10W-40 are recommended.
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 5W-30 is designed to maximize engine performance and help extend engine life.
Mobil 1 High Mileage 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 short initial oil change drain intervals of 3,000 miles as cleanup progresses.
Mobil 1 High Mileage 5W-30 is designed for higher mileage vehicles and to provide the following benefits:
Extra anti-wear additive helps protect critical engine parts.
Reduces the sludge and deposits that 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.
