Customer Ratings & Reviews

I used to use a different brand of oil until my neighbor told me about Amsoil and that’s all I use for all of my vehicles.

Started running AmsOil signature in my 6.4, could immediately tell the engine sounded much smoother. Wish I started running it sooner!

We run this in our commercial mowers and with many mowers well over 2,000 hours on the meter still running like new!

well tested, no need for additional seafoam or other detergents. I used to be a royal purple customer, but this oil is proven to take care of your high end motors.

I use this oil in my 2008 Taurus & my 2015 Ford Explorer... Been using Amsoil for years.

Fast Shipping , Excellence Product A+++++

It cost more because it's BETTER ! I was a royal purple guy for years. ( rightfully so ,it a quality product) but AMSOIL IS ABOV'EM ALL

I have been using this great product, and it has help me keep my many cars and trucks in top running shape, I will continue buying Amsoil product, and using it!

I have been using AMS oil in my 2.0T Accord MT for about 50k miles now and I drive that car like I stole it every day lol, not recommended, But my engine still feels PERFECT at almost 100k miles. I will be a lifelong AMS oil customer!!

I own a 2018 Dodge Durango GT 120,000 miles. I do Courier work and specialized premium logistics for the TSA. On average I drive in between 3,000 and 8,000 Miles a week! The current 0w-20 Amsoil Signature Series that I run in my Durango has been run for nearly 17,000 miles and it is just now starting to lose its golden hue and turn. The oil filter doesn't seem to have any sort of clogs, nor does it show any real sign of decay of the filtering material. And let's not forget one of the most important things, always checking your oil level after a oil change, and I recommend checking your oil level every 3000 miles to ensure nothing is below maximum operating capacity. With Amsoil I have checked my oil every three thousand miles for the last 17,000 miles and the oil level on the dipstick today at $17, 692 Mi is exactly the same level as it was at 0 miles. Amsoil truly is the nectar of the Gods for any automobile owner and I would recommend Amsoil to anyone out there, although expensive I guarantee you that it will save you thousands of dollars if not tens of thousands of dollars over the lifetime of your vehicle or who knows hundreds of thousands of dollars throughout your entire lifetime with all your vehicles! Tuesday November 30th 2022 I will finally be receiving my second batch of Amsoil zero w20 signature series full synthetic as well as a full transmission fluid drain and refill, as well as a rear differential drain in a refill with Amsoil. I am so excited for my Durango

Great product, Fast shipping

Best oil

I have been using AMSOIL products for decades for desert trucks to race track vehicles. You will never be disapointed with AMSOIL.

Excellent protection my hot rod

I had the dreaded 8 speed GM shudder in the transmission and since my 2019 GMC Sierra was due for an oil change I decided to do a complete Amsoil fluid change, engine oil, rear end and transmission. The engine is noticeably quieter and smoother, especially starting from an auto stop. My wife noticed the difference right away. I am pleased with my decision to go with Amsoil.

I've been using AMSOIL since a friend told me how it help his Harley. I tried it in my Jeep transmission and the sound stopped and shifting was a lot better. Now I use it in my Ram with piece of mind that I'm using the best. I can't change my oil anymore, but being able to buy the kit and take it to the garage worked out good. Thanks

In todays world where cars and trucks cost $50k or more, isn’t it worth it to use the absolute best synthetic motor oil on the market? AMSOIL is very transparent with research and testing results, and those results show time and again that AMSOIL products outperform virtually every other motor oil.

This is way better than the oem oil your engine will last longer if you use signature series oil and change it on time.

Running this in two vehicles, Mustang GT and Jeep Cherokee. Vehicles run great.

I've been using this product for over 25 years and swear by it. I use it in all my vehicles and off-road toys. You can't beat this stuff.
