Customer Ratings & Reviews

I have a 2007 Tahoe with a 5.3l engine in it that right now has just under 320k miles on the clock. It has been running Amsoil products in it since it's first oil change. I my heart I believe the only reason it has made it this far is Amsoil.

Its the best/ I use it in my three cars. (FOR YEARS)

Very happy with this product, no complaints.

It's really not worth spending the extra money when it's recommended you change your oil every 3 thousand miles for the extension of the life of your engine!

I like it

The best oil to use for your engine. I am willing to pay a higher price for longer miles and better quality.

Best oil I can find. I change under mfg recommended interval by almost half. I've been a amsoil customer since I won a oil change at a outdoor show early 80s Couple trucks over 300000 miles. The bodies died not the motor. Amsoil!

I’ve been using this type of oil for 10 years or so on various vehicles I have owned. This oil has allowed my vehicles to operate quieter, has lowered the engine temperature, and has improved the performance as well. I have sold and passed some of my high mileage vehicles along to relatives and they are still being used. I highly recommend everyone to try Amsoil for yourself and find out how good it protects your engine’s life.

I recently purchased a brand new 2024 F-150 5.0 4x4. I ran the factory oil for the first 1000 miles and then switched to AMSOIL Signature Series Full Synthetic. I will soon be changing my transmission fluid to AMSOIL as well. From its first fluid change to its very last, my truck will only get the best! AMSOIL.

Use nothing else. You can go for 10-15k and the oil comes out clean. Most importantly it doesn’t brake down and continues to protect. We have an ‘06 Civic and she runs like a champ on this

All the AMSoil products are excellent. There is no substitute for their quality. The oil coupled with an AMSoil engine flush and AMSoil filter will keep running smooth for years. We have a ‘06 Honda civic with over 200K miles and she runs like new. Ourfour other vehicles love the AMSoil just as much and run perfectly. Thank you AMSoil

All good

Oil came as described and got a free magnet dish. Wish I would have gotten decal(s) to throw on the window. Happy with product so far

Been using it since first oil change in 2007 Mountaineer 4.6 3V. Just passed 256,000. No issues and runs like new.

I have a 2016 Jeep JKU Sahara 75th Anniversary Edition. I bought the Jeep when it came off lease because the previous owner had meticulous service records through his dealership. On my first service, I switched it to AMSOIL and never looked back. I do my oil/filter service annually because I generally only put around 5,000 miles a year. With the AMSOIL and a Wix XP filter, I never have a worry.

I would definitely recommend this oil and all there products to anyone.

Great product, better quality than dealership.

I’ve heard good things about amsoil and just bought a 2021 f150 with 20000 miles and wanted to try this product. I wish I had taken an oil sample prior this oil change but will keep updating to let you know how I make out using AMSOIL. Shipping was outstanding. THANK YOU

I have a vehicle with very high mileage that I plan on driving until the vehicle wears out. My mechanic turned me onto this oil. I’ve never been happier with the results.

I have ran this oil in my 2019 Jeep Grand Cherokee V-6 engine, over 85K miles and runs like new.
