I gained 1 mpg and protecting my engine, it's awesome

I've been running amsoil for many years now and this is the main oil that I'll run in all my vehicles, especially anything that's modified. It's wear protection is unmatched and if you order enough oil, it is definitely worth the money. Especially if you are a member. Highly recommend it!

My 09 Accord has 320000km and was using oil and blowing blue smoke occasionally. That has stopped since using the high mileage oil.

Definitely a good oil to use on higher mileage engines.

I’ve been using Amsoil for the past 8 years in all my vehicles and get better gas mileage and less engine wear. I highly recommend this oil on conventional vehicles and on high mileage engines. This product holds up even beyond the recommended change time.

I've been using AMSOIL products for more than 30 years to protect my vehicles engines and drivetrains, it's quality is unsurpassed.

Great oil

I use this in my daily driver 2017 dodge challenger with 120000 miles.I also use it in my daughters 2011dodge charger that has been noted to have valve lifter issues.The charger has the 5.7 liter engine with 223000 miles on it and no engine issues. Very impressed with Amsoil.

I have about 1000 miles on since my change to this oil , so far I love it I have gained 1 mpg total with normal driving!

Perfect Lubricant for my 2013 Buick Enclave. I keep it in for a year usage. Can’t quite get 20k km in that time. Basically get just over 2 cycles on one charge of oil. Saves me money

Nice and quite with thos fluid.

Fast delivery and always the perfect amount of oil

I had been using mobile 1 synthetic for every oil change and it kept burning oil and struggling with acceleration and power. Once i changed to amsoil even my wife came back to me and said “wow its so smooth and quiet dont have to push down the gas pedal as much to get up hills “ so grateful we found this!

Use this is our 2019 Ascent that has over 90k miles now. Runs great and stands up to the extreme cold we get up here.

All I use.

I just switched from the Signature Series to this High Mileage. Only have gone 1,000 miles and my mpg is 3 mag better than with other brands. My vehicle has 84,000 miles on it. Doesn't burn or leak any oil.

I have always used Amsoil in both my vehicles. Would use nothing else.

Got my cousin started on this oil for his wife’s higher mileage car. Oil consumption cut in half over a longer period

With 227,000 miles on my 20212 Camry I could feel and immediate smooth engine after switching to Amsoil. Highly recommend, can go wrong!

I used amsoil XL when was 12k miles and now that switched to higher and the High mileage is still 12k miles and hopefully since my vehicle is above 75k that it will give that added boost we all have trusted amsoil with and will use til my vehicle decides to no longer be
