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.

Rated 5 out of 5 by from Great Oil We have 2 vehicles, a 2003 Ford Explorer Sport trac, and a 1999 VW Jetta. Both have high mileage and I am a sticker for changing the oil and filter every 3,000 miles. This oil has held up to it's reputation but believe that Exxon Mobile could throw a few coupons our way once in a while. I perform most of the work on our vehicles and would like a discount every now and then. If you look on their web site the coupons that they have list all expired in 2014. Come on guys catch up and give us self doers a small break. Love the product but believe that Exxon Mobile could help out the little fella here. Jim Barnes El Paso, Texas

Rated 5 out of 5 by from My 2001 Durango 5.9L is purring like a kitten Hi, bought a 2001 Dodge Durango with a 5.9L Magnum V8 about a year ago. This engine is known for blowing up and for burning oil. I was using Valvoline conventional as I always had in the past, but she did not like it at all. She ran rough and was using a quart between changes (3000 miles). Switched to Mobil 1 HM 10W40 (went a little thicker since it gets super hot where I live) and immediately noticed how smooth and quiet she ran and she has not since used any oil. I have great peace of mind now with this oil in my engine and even my gas mileage has improved by one mile per gallon.

Rated 5 out of 5 by from Proven. I have a 09' Altima with 110K miles on it. I drive and sit in Boston traffic every single day of my life and Mobil 1 High Mileage is all I have used since my car turning 75K miles. Prior to the High Mileage, I used regular full synthetic Mobil 1 5w-30. In all honesty, my car sounds great. Very quiet, smooth, people often comment on it, especially being a 4 cylinder that takes a beating with Boston traffic. I change my oil myself every 5,000 miles and it still looks good. It is impossible to go wrong. Sick with Mobile 1 High Mileage with a Mobil 1 Extended Performance filter and you'll be more than fine. Be good to your car and your car will be good to you for a long time. After all, who likes a car payment?
