Customer Ratings & Reviews

I have been using this motor oil for years and it keeps my engines running better than any other oil out there.

Love this oil, works great in new cars! I’ve been using since I got my 2019 Jeep Wrangler oil still looks like new even before oil change and I go about 10,000 miles between oil changes.

I recommend amsoil To everyone who want the car to last longer Time The oil make your car drive smoother I call it the Liquid gold You have to try to believe it love it

I use this Amsoil in my 2016 f-150 show truck, I use it in my 2020 Platinum both 5.0 coyote motors, I use the most expensive diesel oil in my 1995 F-350 powerstroke 4 x4 with only 51,000 thousand miles, no lleaks, and it added a couple of miles to the gallon . This Amsoil is the best all around oil and other products is all I use around my trucks, my tractor, my wife’s 2019 Polaris ranger, 1000 northstar edition, and my 2002 Banshee. Wouldn’t use other products that’s not Amsoil.

Products arrived fast and packaged well. AMSOIL even threw in stickers... Don't wait, become a member and enjoy the savings with quality products...

Abouslety the best oil on the market with all the best additives in AMSOIL I've done alot of research on AMSOIL and it is in the top 3 and will continue to use this product from now on.

I tell everyone i know to buy amsoil. If I argue with them for an hour or so just to prove to them this product is the best then so be it because no one is going to tell me liquimoly is better then amsoil.

All my cars get the sig series. Perfect for daily performers.

I have a well built 500hp Chevy Avalanche and Amsoil is the only oil I fully trust to keep my motor alive.

From all the other brands I have used this is the one I like the most. It gives me good performance out my engine.

Signature Series 5-20 motor oil In my 2018 Jeep Wrangler Rubicon 3.6 V6. Totally the best ever. I had a rattle upon start up , hot engine or cold. I tried several different motor oils including the dealer recommended, it still rattled at start up. I researched endlessly, come to find out the factory says it's normal. Well I didn't like it. I used Amsoil in many other internal combustion engines , so I thought I give it a try. So happy I did it completely solved my rattle on start. I use in everything I own now. Thank you Amsoil.

Being using it for a really long time, makes the car really smooth

I am always going to use AMSOIL for all my cars. The engines run smooth and I have the peace of mind that this synthetic oil has a lot proven testing.

I redline my RAM almost every trip and went 17000km last oil change and could have gone another 5000km

I have been using only Amsoil products in all my vehicles for the last 15 years. It came by word of mouth from a friend/mechanic. 10 years ago I became a member and have saved a lot of wear and tear, not to mention the money I've saved. The final convincing came at the hand of said mechanic. I had him put gaskets in my 1999 HD from the crankcase up, as mine were starting to seep a little just from age and poor design. He said when he took the jugs off the cylinders still had the crosshatch pattern from the hone they did at the factory! Enough for me! It's all I use!

Never ran any high end synthetics so decided to try signature series, within 5 seconds of starting the motor; it has never run quieter. Barely any valvetrain noise on my 3.5L ecoboost, looking forward to seeing how it looks when I change it out in 11 months.

So far engine is smooth

Ive been using Amsoil Signature Series in all my rides for plus 20yrs. I usually keep my cars & trucks 150-200k miles or until the wheels fall off, trouble free, which i accredit to Amsoil. I've used it in vehicles that have had bad reputations for engine/trans breakdowns and had no problems. I highly recommend it.

Great product, been using for years, would definitely recommend!

Great oil, will continue to order as needed
