Customer Ratings & Reviews

I started using Amsoil in the early 80's, at first was kind of skeptical because there was nothing else like it. Over the years Amsoil has gained my 100% trust. I've used their products in my cars, trucks, motorcycles, yard equipment, and emergency generators. Never once have I had the first issue or a question in my mind that it wasn't living up to it's reputation. Amsoil always seems to be ahead of the game when it comes to updating to new standards, sometimes it takes off the shelf oil months to meet the new standards. If I order over the weekend it's on my doorstep Tuesday. No need to run from store to store looking for a gear oil, transmission fluid, coolant, or any of that kind of stuff to service you're vehicle or equipment, Amsoil pretty much has it all.

I changed oil brands from Mobile 1 to amsoil. I could feel the change in power and fuel mileage almost immediately. Love it..

Have been using this Signature 0w-30 in my Alfa Stelvio since it went in for it's first required service. The dealer service writer was ekeptical that I was not allowing not using their oil but the attending mechanic quickly informed the service writer that this was probably the best aftermarket addition for these vehicles. I also used the AMZOIL filter and have been changing the oil at 7500 miles. Have 30K now and the oil comes out almost clear during changes.

Truck got quieter than ever before great fuel mileage with this oil and will only run this in my 2022 silverado

excellence oil been using it for years would recommend to anybody

I bought a new 2022 Subaru Outback and I believe Amsoil is the best oil there is. Protecting my investment the best way I know how.

Buy this oil.

I got a new turbocharged direct injection car so I figured I wanted thr best of thr best. I mean I use Pennzoil platinum on all my cars which is a good product already but on this car I wanted the best so decided to use Amsoil. I might change all my cars to Amsoil now.

Incredible products and results.

Only the BEST motor oil for my Infiniti Q60 Red Sport & she loves AMSOIL! Thank you!

This oil was the only one I could find that met and exceeded the requirements for my turbo direct injection KIAs, These motors have a nasty habit of grenading after years of unheard detonation to the point of all of them being given lifetime motor warranties by the dealer. The extra warranty given by Amsoil is a nice bonus. I follow the factory change intervals regardless of the oils suggestion as $60 plus a filter a year is cheap insurance.

Had to listen close to hear the motor running. It's amazing what they can do with motor oil. More HP I can feel it.

Best lubricants in the market. Reduced engine wear especially on start up

Hands down the best oil on the market!

I use Signature Series in my 2017 GT350. I track my Shelby so its run hard, often. Amsoil Signature Series has protected my engine, I have no oil related issues what so ever. I highly recommend Signature Series for your high performance engine applications.

I have been using amsoil for 2 years now and since the lifter noise no longer exsists.

I have a LEXUS ES 350 and change every 4000 miles and this oil never fails! My 2006 Subaru STI use to burn through every oil but not AMSOIL!

Amsoil has priced themselves out of my business Oil is great but at what point is to much

Great product and great service

After extensive research I found that the best oil for my 68 vette is signature series 5W30, after all the hours of work it took to get every part of this project just right why would I settle for motor oil that is just ok.
