Customer Ratings & Reviews

Just bought 2021 tundra ,when i get 5oo mile ,1st oil change with Amsoil 1000 miles change ,3000 ever after.

Hands down the best oil for 4Runners in my opinion. Whether you are in city traffic or over-landing, I’ll bet you sit still and idle for awhile. Just let that sink in a second…….

I have using Amsoil in my all my trucks for years and the just keep going and going and going

This is the only blood I will put in my truck. I plan to keep my truck a long time.

I have been using Amsoil products in ALL my vehicles & now children's vehicles for over 20 years. Best stuff on the market. First experienced synthetic oils in the Navy back in the early 80’s and thought there’s a reason for “mil-spec”. There’s a lot of synthetic oils on the market, yet none that offers superior protection like Amsoil. Living in the southwest where ambient temperatures can reach 115 degrees in the summer it’s nice to know my vehicles lubricants are top of the line.

I run this in all my cars and trucks, best oil on the market

Great product fast shipping!

My 2017 WRX, (not STI), rund like new and I've used Amsoil Signature Series since 10,000 miles. I have 68000 miles now and while I change the oil every 3000 miles due to modifications, 368 WHP measured on the Mustang dyno, it never misses a beat. Sure, it's expensive, but so are all the other boutique oils out there such as Motul, which by the way gets beat hands down by Amsoil in independent testing. There just isn't another oil with the proof to back up the claims like Amsoil, is there? If so, please do tell!

Best oil ever that I’ve used in my Genesis.

Always run Amzoil

Have used AMSOIL products for over 30 years.Would not use anything else. Use in trucks to incude diesel,cars,small equipment, 2 cycle engines and other types of equipment with great sucess.

The product is 2nd to none

Changed my wife's oil in her 2018 civic sedan with the 2.0l ...ruff idle and the engine vibration would rattle the dash....changed the oil with amsoil and it runs way smoother and no vibrations whatsoever

I’ve used Amsoil in my Silverado for two years now and all the hype about amsoil products has held true for me. We have drastic temperature swings from sub-zero winters to 80-110° summers. My truck gets mild- heavy use and after a years use I was a little low on the dipstick but the viscosity was still good and the filter still working well. Not to mention My oil used to get changed three times a year@ $70 a pop, I’m not change my own once a year at about $115-$120 a year so I’m saving money.

I think this is one of the best oils I have ever used. I'll tell you why. I'm busy so, having a longer life means I change oil once a year and feel confident. Also, it's save gas. MPG is better than with other oils. Those are my main reasons for sticking with this brand. Over 50 of me changing my own oil, I can tell this is quailty.

This is an awsome product!!! In have been using this oil in my vehicles since the mid 70's !!!!

I use all amsoil products! From chainsaws to Atv to all my vehicles and have had great success with each!

Best oil ever

I am a repeated customer of this oil, and I have only had a great experience with it. I only change my oil once a year, and my car runs very well. I am very happy with this product.

Been using Amsoil for years and never had an oil related problem including leaks.
