Customer Ratings & Reviews

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😂😂😂

Always had good performance using Amsoil full synthetic 0W20. This Honda CRV has over 200,000 miles on it and my last Honda Accord had over 500,000 miles before I let it go. Amsoil always performs!

I've used Amsoil lubricants, filters and associated products with great success for more years than I can recall. The synthetic 5W-30 gives me peace of mind should i need to extend the oil & filter change beyond my standard 1 year basis. I also use their engine fogging oil, synthetic greases, engine & trans flush, gas stabilizer, chain lube, oil & filter kit for the "V-Twin", and many others. I especially enjoy the non-smoking results when Saber is used with the 2-stroke lawn care engines. Now if these products were just a little less expensive (hint, hint).

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've been using this for my 17 Honda CRV for the past three years. My wife drives about 6500 miles a year, so I end up changing the oil 1x a year. Changing the oil myself is about 50% less than taking it to a shop. I like the single pour quarts, much easier to pour the correct amount than using the 5 quart jugs. I am also going to switch over to this oil for my 22 Honda Ridgeline for its second oil change. I highly recommend Amsoil.

Great product auto and marine oil gives you piece of mind.Amsoil is honored by many auto and marine companies because of reliability and longevity. I have been running this product for years, oh yeah small engine oil flawless .

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.

Amsoil in truck 3 days, ford says “cam phaser rattle” looks like your due for a oil change “based on window sticker” nope just did it 3 days ago, well your getting a fresh one anyways. Sooo bummer

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.

I have to admit that I use amsoil signature in 3 of my vehicles and the motors all run smoother and quieter then ever before.

This is a product that I've used for years now. On my 4th vehicle that I've gotten the Amsoil into the engine as soon as possible. Have had NO issues. With a little time fuel mileage has increased a little since the engine is running smoother, and reduced the "Hemi-tick" too.

Great stuff as always! Good filter too. I use Amsoil in all my vehicles

Forums recommended amsoil for my 2007 Toyota Tundra with 224k miles on it. It quieted the líderes immediately with start ups. Quality oil!

I use it in all my cars and SUV Subarus Crosstrek and differential systems

I love that this oil helps my pick up to get better fuel milage. I have a big block V8, 8.1 liter, Im need all the help I can get.

Amsoil is one of the best products on the market. With independent testing Amsoil oil consistently rated at the top .

I have used Amsoil for all of my vehicles for over 20 years. It may be a little more expensive, but it last longer and has the full backing of the manufacturer. Something you don't see much anymore!
