Customer Ratings & Reviews

This is the least expensive oil Amsoil produces but it will not beat Mobil 1, Royal Purple, Pennzoil Platinum or Valvoline Advanced in comparison tests, yet all of those oils are similar in price. Amsoil is pricing itself out of the market.

Its good.

Just like all of the Amsoil products it is excellent quality with super support!!!

I changed from signature to OE because I want to still do 6 month oil changes. Truck engine was switched to Amsoil after 1000 miles. Engine runs smoothly like ball bearings on glass. 2021 Ford fi50 5.0 coyote

The price is really what drew me to this one. I have seen so many videos on how AM soil makes their products. From what I’ve seen, it makes them a company that I want to support.

Great oil seems like it gives my truck more power.

Amsoil wants a review. Ok I have used the oil for my 2015 Ram 1500 Hemi for over 2 years and my truck runs just fine. Oem owners manual recommends change about every 10,000 miles depending on driving conditions. Mine is mostly highway, Amsoil implies it is good for about 25,000 if I remember right. I checked at 15,000 was a quart low. Topped it off. Will be changing at 20,000. Engine runs and sounds fine, oil looks brownish, not black like the other syn oil I used which I changed every 10,000 miles. Very happy with the savings.

Excellent product

great product

I know this oil, for use on working cars, I have not used it on my personal one yet!

After great lengths of research I found that Amsoil 100% Synthetic Oil beat the competition in quality testing. I really like that they give you an actual gallon of oil , not 5 qts. Most smaller cars today only use 4 qts. I recommend their product!

I have used this oil in my truck after the first 3000 mile oil change changed every 5000 mile I have 292000 on it as of 09/24/2022. I have not done anything to the truck at this time.

Since i started using amsoil the ticking noise fro the valves is gone. The engine runs real good now. Thanks for excellent product.

Since i started using amsoil in my Honda Crv, it is running a lot better.

Used it on my 2011 Escalade Ext and the difference was amazing. The truck performance was noticed from the start of the engine.

This oil came recommended for the particular engine in my daily driver that I drive about 90 miles a day with. This being the first time I have ever used a synthetic oil,I tried it, and am pleased with it. I am on the third change with it at 5K mile intervals. It seems to hold up very good, over all , it gives me confidence that I am running the right oil and will continue to.

Use it in all my equipment, cars, trucks & diesel tractors

I have been using this oil in my 2019 Santa Fe since it was brand new. When the valve cover was replaced, the engine looked brand new inside. Switching my Genesis over next oil change as I just bought it.

This is excellent oil. I use this in my 99 Honda CRV with 301,000 miles on it. It doesn't burn a drop between oil changes and will continue to use it. It is a little more expensive, in my opinion, than what I could pull off of the shelf. I won't mention the brands.

With what a vehicle costs these days, why would you use ANY kind of motor oil that DOESN’T Say 100% synthetic?
