Preventive maintenance that includes high-quality lubricants is key for keeping vehicles safe and dependable for the long haul. AMSOIL 5W-30 100% Synthetic High-Mileage Motor Oil is designed specifically for the unique demands of high-mileage engines (or engines which have been using oils which left deposits), helping extend the life of your vehicle.
This is the first step to help clean up that engine w/o needing to use an engine flush.
It delivers purpose-built protection at a time in your vehicle’s life where it could benefit from more-robust maintenance. It cleans and protects engines with boosted detergency and an additive package that fights oil breakdown and oil leaks.
I suggest a couple changes with this oil then switch to XL or Signature. This is a great choice should you buy a used car with over 80K on the odometer or that vehicle you really don’t know the history.
LOWER Cost than the XL Line!!

Outstanding
By CHRISTOPHER, a Verified Buyer on August 06, 2025
I have a 2018 Subaru Impreza. I was starting to get bad gas mileage around 145,000 miles. I switched over from using OEM oil and filter to using a wix xp filter with this oil and my gas mileage went back up significantly. Also, my engine sounds like it is idling more fluently and quietly again. I can’t say enough good about this product, I will be a life long AMSOIL customer.

My 2019 Acura RDX with 132000 miles started running real smooth and quiet after I started using this oil!
Great oil in my truck
By RONALD, a Verified Buyer from Aiken SC on June 18, 2025
Changed oil on a Friday night. The next two days drove 1600 miles to pick up a gift from ebay. When I got home the oil was full and same color as new high mileage oil I installed. Great trip, great oil. 252,000 plus miles on 2003 Silverado.
Pure gold for my 213,000 mile Jeep Wrangler
By WILLIAM, a Verified Buyer from Eatonton Ga on July 08, 2025
I had 12,000 mile oil tested and the results were surprising as to how good the oil still was. I’ve used this oil for 4 years and my engine has never run better and uses no oil.
