Customer Ratings & Reviews

I purchased Amsoil for my 3.6 LFX V6 Camaro. I went about 6k miles and changed the oil in the engine. I sent out a sample to an oil analasys lab and the results came back great. They recommended going 8k miles before changing the oil again because there was still plenty of "life" left. I will continue buying Amsoil.

Great Product , Fast service, good price

I've bought this oil after watching YouTube videos of it beating out the other oils people buy. I usually do royal purple but not anymore. This oil cause less wear and tear and my car runs more smoothly. The best part is it's 100% synthetic. Royal Purple isn't. Great product. Definitely going to buy again.

I have been using Amsoil for 25 years and never had engine issues. Great products!

I have been using Amsoil for over 30 years and think it is the greatest. I use it in all my cars, mower, and mix the marine oil with gas to run in my chain saw, weed,eater, and hedge trimmer. I recommend Amsoil to everyone who will listen.

Just sold my 07 Prius with 200K. Used 1 quart in 19K as topping oil. Never had the head or covers off, changed plugs twice.

use in all personal vehicles and equipment

Doesn't burn off like other oils this stuff is amazing

I use Amsoil in all my motors

I keep buying this product because I now have 379,000 miles on my factory 1.4 turbo GM motor

I first started using Amsoil 10w40 in 2015 in VTX 1800. Then in 2017 started using oil in 2014 Patriot. Cooler, quieter and better mileage. Longer intervals between changes. Will not use any other oil in any machine I own as long as Amsoil makes it.

I mean its a really gold Oil and as a memeber you get It for the same price as anything else on the market. How do you go wrong. I got 300k on my car and still going strong because of this stuff.

i use only Amsoil signature series for the past 20 years. the best lubrication, protection and no gumming.

i use only the best oils, and this one is one step ahead of everything ,car runs smooth, cooler and much efficient ,thanks!

I have been using AMSOIL in my vehicles for 37 years, for better fuel economy, better engine, transmission, and rear end performance, and much better protection for all vehicle components. I love this new oil upgrade for its protection, particularly against preignition. Pulling a trailer in hot summer weather with a turbo engine makes this kind of protection mandatory.

I've got a Shelby GT350. Voodoo engine is very special, and also very expensive to replace. While I can't 100 percent say amsoil has kept me out of trouble. I've beaten the tar out of the car at the track and barely consumed oil unlike many others. Will continue to use the product on this car!

I use this oil because of extended oil changes .... I change mine every 10000 miles but rated at 15000 miles. Currently have over 240000 miles on engine and have used it since new so very happy with engine life

Have two 5.7 hemis. One is higher compression with forged pistons( ie: burns a little oil). Oil consumption with Amsoil is 50% of other oils. valve train is noisy on 5.7 hemis. Using Amsoil reduces noise 75- 80%. MPG on both vehicles has increased. Best oil I have ever used.

I have used Amsoil products, exclusively, pretty much since I first heard about them back in 1977! Motor oil & filters, trans fluid, differential fluid, grease, MP, YOU NAME IT! I have NEVER had a lubricant-related failure, or wear-out, since! These are simply THE BEST LUBRICANTS MONEY CAN BYE...PERIOD!!!

This oil is absolutely the best product, I've been using Amsoil for more than 30 years and this is without a doubt there best product ever for most cars and trucks
