Customer Ratings & Reviews

I run long miles in between changes. My vehicles run great! Use top tier oil filters. Engine clean.

Feels good knowing I’m putting the best oil in my evo

Absolutely amazed while pushing the 10,000 mile service interval and still performing! This is liquid insurance at its finest. I changed out all of the fluids in my ‘08 Tundra 5.7L over to Amsoil and noticed unique differences. My transmission thanked me the most , thank you!

Let's be real, 0w20 has the consistency of water. I've had impressive results with Amsoil in my other vehicles so when it came time to change the oil in my first ever turbo car that uses such a thin oil it was a no brainer. Not sure what was in the car, likely dealer bulk (used car), but I just did my first oil change to Amsoil. I'm not going to blow smoke up your ...., but anecdotally runs a little smoother and revs a little more willingly. A bit more noticeable is that I'd swear it spools up faster. I like to indulge a little with my right foot and I feel better with Amsoil in there now, particularly when such a thin oil is spec'd.

Being on the heat. I’m usually Amsoil in my Kohler. Great product

Best oil ever used. This made me switch from another good brand (with funny color). 2000 miles and still looks as if I changed oil yesterday. Car is noticeably smoother and quieter at idle. Cant wait to try other Amsoil products too.

Did an oil change on a 2007 Honda Accord V6-EX that my brother in-law bought for my niece. After using the Amsoil engine flush and adding the oil, it made it run like new. I drove it back to Illinois with her and it ran smooth as silk and quiet. The Accord had just over 99,000 miles on it when purchased.

Great high quality product

No issues with product. Seems to be working

I been using Amsoil on my all car’s and vans.this oil is excellent .I like this oil and I recommend this product.

Just bought a New Ford F-150 3.5 V6 twin turbo 4wd. Three days later I dumped the stock oil and filter and replaced with Amsoil Signature 5W30 oil and EAO 17 filter. I wouldn't have it any other way. Have been a Amsoil freak for many, many years. It's the best in the Business !!

Very clean at this point will not run anthing else in my motor very satisfied....

Great oil. Going to try it this time and see how it goes.

I've used this oil in my fleet of for cars/trucks for at least 10 years. Put 200,000 on most rigs, which includes some tough towing. Engines run like new thru-out thier lives. Appreciate the better gas mileage and convenience of changing oil once per year. Line them all up and change them all in Spring; then done for the year. Great stuff! Never had an engine start to burn oil using this product.

This oil has been fantastic for my '10 Challenger SRT8. Never fails to impress. I've tried out some of the extended range of the oil with the Amsoil oil filter and I've never had a problem although I do prefer to change more frequently. Great product. Highly recommended.

This oil is amazing. All of my 7 vehicles have run with Amsoil and it keeps them running a over 200,000 miles each.

I use Amsoil in all my favorite toys, it’s peace of mind to know I have the best oil possible

I love Amsoil and all of their products. Amsoil is the only oil and filters that I will ever use. My 2005 Scion xB had 219,000 mile on it and runs like a new car still. Without any leaks at all and has never given me any problems. The same goes for my 2018 Triumph Bobber motorcycle and my 2013 Subaru Forester. Thanks to running Amsoil and changing my oil when it should be changed. I highly recommend Amsoil along with their products to anybody, that wants a long life and a trouble free vehicle. It's the only oil that I will ever use.

I'm a new customer , 40+ year technician. I am always looking for the best product to maintain my vehicles. At this time will continue use AMZOIL and will be able to determine how I like it.

I have only had the oil in my car for a month, but i have had no noticeable problems. My friend has been using it for several years in his vehicles and is extremely pleased with the performance.
