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

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!

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.

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.

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.

Do the math

Granny shifts so much smoother and up shift just right now

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.

I have been using the 5w30 all my trucks with this in have over 300,000 miles. Now have a jeep calling for 5w20 on my second oil change oil looks like new. I believe in this oil and in the winter trucks start get oil pressure right away.

I tell you that I did not just believe what a company ad or just like look a t a pretty Package I talked to people for years individual and dealers who use the products. If I was poor then you get what you can afford to get the job done. But if your smart and you research and do your calculations, you can see the value in a premium product. And you research what other oil MFG's get to use to classify a conventional oil as a synthetic!

I just want to say as a first time customer that y’all are the best in the business and please keep up the great work. Y’all are stuck with me for life😂😂😂

I have been using this oil in my wife's equinox for five years and have zero problems. The car burns no oil and the gas mileage is great! Te equinox seems to run cooler tan when we first bought it....

I have been solely using Amsoil since 1990, I drive about 10k miles a year and I like the once a year oil & filter change.

I have been using Amsoil alway in my vehicle great product

This is truly a great oil. I change my 2020 Ford Raptor oil every 5,000 miles and it is virtually negative on all wear particles per the oil analysis I send in. My only gripe about this oil is that it is far too expensive now days! Inflation is one thing but you have raised the price far more than seems necessary.
