High-Mileage Synthetic 5W-30 Motor Oil
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.

Never too late
By CHIP, a Verified Buyer from De. on June 03, 2024
I’ve used Amsoil for years with unbelievable results. My 2007 Triumph motor cycle is getting close to 100K miles and the valves, which call for valve adjustments at 7000, still doesn’t need any valve adjustments. Now I just bought a 05 Tahoe, and changed the oil as soon as I got it. I just wish it had a steady diet of Amsoil through it’s life. And now I have to hope this High milage formula will make it so it runs for many years to come
Motor is smooth

Decided to try Amsoil over my go to royal purple. I am super impressed! No more valve chatter at idle
Switched to amsoil
By JEREMY, a Verified Buyer from Maryland on May 05, 2024
Switched to amsoil about a year ago in my 2015 JKU . Since the change I’ve noticed better starts and smoother acceleration. And small gains in RPM and power in 5th and 6th gear. (even with the ac on)
Coyote 5.0 F-150 This saved me quoted $4,000
By DAN, a Verified Buyer from Kansas on April 04, 2024
All Ford F-150 5.0 Owners with issues, Rough idle and dies at stop lights, sends multiple codes Timing, cam position sensor, VVT. After I took my 2016 F-150 165,000 miles, in for service, oil change, the check engine light came on and it started idling rough and dying at stop lights, when I talked to the mechanic he told me it was cam phasers and it would be cheaper to replace the engine $15,000. of course I got a second opinion, they said I needed to change the timing chain, and rebuild the heads $4,000. I decided to do some research of my own, found that many Ford F-150 owners had the same issue, many different tried fixes none worked, Changing the VVT solenoids seemed to work for some of them, so I purchased one of them so I could see how they work, long story short the VVT solenoid is piloted by oil. Oil in this engine is critical in the operation of the F-150s variable valve timing VVT, I looked back at the oil change records and they actually listed the brand and weight of oil they used in that last oil change Havoline 10W-30 and a Fram oil filter, that’s when the problems started!!! So I decided to try an experiment. I drained 1-quart and added 1-quart of engine flush, ran engine for 5-mins, drained all the oil, installed a new oil filter from Amsoil, and filled with Amsoil high mileage oil, I noticed immediately the sound of the engine was so much smoother. the check engine light was still on, but it ran so much better, after about 50 miles of driving the check engine light went off, I’ve been driving it now for about 4-weeks 300 miles, no issues with rough idle and hasn’t died at a single stop sign or stop light. Thank You Amsoil !!! saved Me an engine replacement and a whole lot of headaches!!!!
