Provides unsurpassed wear protection* that helps extend engine life

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.)

Still have additional questions, such as, "Should I use high mileage oil?" or, "Is high mileage oil worth it?" Watch "The 500,000-Mile Challenge" to learn more about the benefits of high mileage oils.

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

*According to the industry-accepted Sequence IVA engine wear test.
