Customer Ratings & Reviews

I use it since I don’t remember when and I don’t worry about my car’s engines at all for a full year. Protection at it’s best. Just try it once…the rest is history.

This oil has made me feel more confident in my truck it runs smoother and it’s a hair quieter I feel like my engine is going to last a lot longer

This is a superior product that can be relied on in any weather situation. And any engine load. It's simply the best.

I've been using AmsOil products for 30 years. It's by far the best synthetic you can buy. They always are improving the products and keeping up with market trends and new technology.

GREAT ,FAST SHIPPING, I mean really fast. 3 days fast. Not just once every order is fast. And if there's a problem it's corrected, usually with no returns or questions.

Use in my 2015 Jeep Grand Cherokee. Engine stays clean inside, and weel protected!

Amsoil is the best oil on the planet. Makes the engine run quieter and get better mpg. One of the other biggest benefits is I never had any kind of oil seal go bad using Amsoil.

Good oil for 2021 Jeep Gladiator with the Pentastar engine.

I am impressed with this Amsoil oil. I intend to use both in every vehicle I own going forward. I highly recommend Amsoil products.

all my vehicles seem to enjoy the good stuff. smoother idle , less engine ticking , and longer intervals before change . and American made .

I have been a fan of this oil for years. After switching from OEM oil to this oil it seems as if my valve train was quieter and the motor is just smoother while running. With the price of new vehicles these days taking care of what you have is a high priority. This oil delivers on all fronts. Great product.

Tried this product for my 2015 chevrolet malibu as I was told by a friend it would smooth out my rough idle and I'd notice fuel consumption savings. Never noticed any change and have only 2000km on new change.

Amsoil hasn't let me down yet. In my book Its the best oil on the market today.

0W20 I have used Amsoil. for 40+ years. 0-20 is used in my SC Tundra. Just in passing I use Amsoil in all my car & trucks & lawn equipment. If my vehicle use any type off oil I use only the best AMSOIL I just added SAE 250 to my F 250 & Tundra.

I took my car to the dealer for the factory warranty one time oil change. They used their brand name oil. I had to add oil before the next scheduled oil change. When It was not required to maintain the warranty I switched to AMSOIL Signature 0-30. I no longer have to add oil between oil changes.

Do the math

Granny shifts so much smoother and up shift just right now

AmsOil products are always top notch, and their service is excellent.

I have been using synthetic motor oils for over 2 decades. I KNOW they are superior. I have seen engine teardowns after the use of synthetics and the difference between a quality synthetic user and not is striking. I switched, permanently, from the biggest named synthetic brand to Amsoil. I know some of the top builders swear by Amsoil, and when I heard someone speak of an increase in operating temp oil pressure I gave it a try. My vehicle with a brand new early 90's OHV push rod V8 gained FIVE FULL POUNDS of oil pressure at idle and operating temp. I was blown away. With the superior protection of synthetic, the lubricity of Amsoil, I am totally sold. I recommend Amsoil to anyone that wants to get the maximum out of their engines.

I have been an Amsoil user for 15 years, so when I bought my new Mustang GT it was a simple choice to go with Signature series 5W20. There is quite simply no better oil at any price. There are others with gimmicks and dyes and wild claims but, if you look at the evidence, the choice is clear.
