Customer Ratings & Reviews

I started using Amsoil back in the 70's (I believe I was back then). First I bought compressor oil and the compressor is still used today every day! Every carn truck, boat, compressor, motorcycles and garden machines use Amsoil! I have even proved to my friends just how great a oil it is. I sold one of my work trucks a while back that had over 386,000 miles on it, never leaked a drop and never use a drop and the oil pressure was still great. If you do regular maintenance then your equipment will last forever! Even today I just bought 2 new used year old Kia"s, one for the wife and the same one for myself and the first thing I did was to replace the oil with Amsoil 0W-20 in both of them. You can give me any other brand of oil for free and I will give it to anyone who wants it. I've been a confirmed customer for years and I will never use any other oil... I love my machines too much....

Amsoil products far exceeds the competition. I switched from 0-20 to 5-30 for a little more protection. Engine runs quieter and smoother.

Little more than Mobile 1 but you get what you pay for.

LONG time Royal Purple user. Was getting low OP in my off road vehicle for some reason. Decided to test out the hype of AMSOIL, that was 5 years ago, and I have not gone back!!! Oil pressure is where it needs to be, engine runs smoother, and engine actually stays cooler!

oil change is due and wanted to use a different type, I used to use 5w-40 castrol European. However, I was looking into 5w-50 from Castrol super car gt or amsoil. Did a lot of research and came to the conclusion that amsoil is the best and safest oil to use for superchargers applications. Only if you’re going to keep your car forever and track use. Once I change the oil car runs and shifts so smooth however you will still hear the clicking from the engine lol. Other than that 10 out of 10, thank you amsoil! I’m going to stick with amsoil forever and use it for my other cars and trucks!

My 2008 4Runner just made 200k miles! Have been an Amsoil user for the last 15 yrs! To date, my car still drives like new. Thanks to Amsoil.

Excellent product

AMSOIL came highly recommended so I wanted to start right off on our new Tundra. Ordering was easy, quick delivery. Fair price. Will continue ordering online and using

This oil was recommended to me by some fellow Jeep Wrangler 2.0 Turbo owners. These 2.0 Turbo engines have a slight rattling/knocking noise somewhat like a diesel engine sound with normal oil. These Amsoil Oil quiets the engine and now it sounds like a normal gas engine. Jeep started using the 2.0 back in 2018. Some of the friends of mine have over 100K miles without any problems using the Amsoil. I’m sold.

The Jeep 3.6 valve train noise is totally gone! I have tried many different brands of oil, but the valve train noise always comes back in a day or two after oil change, AMSOIL is definitely far far more effective.. Cam and lobes along with rocker arms all look new..

Using this oil and matching oil filter on my 2023 last call Challenger Hellcat. Was told by a tech at the dealership this oil is far superior to the oil they use and I figured it is a cheap investment to ensure I get the most out of the car considering how much it would cost if I had to replace the motor.

I have been using Amsoil for years now, and it has made a major difference in the way the engines run. There are more quiet; that tells me Amsoil provides superior protection versus other premium synthetic motor oils. Also by changing the oil only once a year, it is actually cheaper than doing two or three oil changes with other motor oils. Keep in mind I use the Amsoil oil filter along with their Signature Series oil when I do oil changes annually.

Signature series is my go to. I love it

Very good product. I’ve been using this in my 6.6L diesel and have over 220,000 miles and still going strong

Hi I am very impressed with this product it is high quality and i trust it completely.

Superior service and performance far exceeds other motor oils ! I’m a true believer I only use Amsoil products !

Keeps all of my engines running at peak performance. I do not worry about Libercation when I'm using amsoil.

My 17 year old engine has never run quieter or smoother

This oil is perfect for my 800 hp Mustang! I love it! Trust AMSOIL will protect my car to the furthest extent!

I have been using AMSOIL motor oil for many years, at least since 2014 maybe earlier. I had read about a ball bearing test and very good results, so I decided to tr5y it in both my Harley and my Nissan 350z. Both ran very well and seemed to like the Amsoil. I usually use either high mileage synthetic for my Z at 170k miles or in my Harley and newer cars signature series. I just changed my oil yesterday at 10,000 miles on my 2024 Acura Integra Type S. this high performance 4 cylinder is fantastic and is a high revving engine, so it is important for peace of mind to have the very best oil in there I can. I changed it at 1500 miles, after break in then again at 5000 miles, and now a 3rd oil change at 10kl miles. I feel very good about it. My car runs excellent and after new oil, filter, and air filter it seems renewed, and healthy, it just feels good to know I have new Amsoil in there, good for 25k miles and it will never see more than 5000 miles in my car. Engines are expensive oil not so much, change it often.
