I put Amsoil Signature in a 2022 Toyota Corolla for a couple reasons. If I have to use thin 0w-16, it will be the best engineered oil I can find, and last through the Summer heat, and subzero Winter starts. I believe the specs show Amsoil is going to do the best job , and with enough volume purchased the pricing isn't much more than other oils. I run it in all my cars.

Bought a 2011 F150 with a 6.2 litre had a 165k . 3 years of using Signature Series 5w20 my oil consumption has gone down 50 percent, Now at 217k

One of the best 5w30 synthetic oils available. First in synthetics.!! A++

Switched from Pennzoil UP to Mobil 1 to Amzoil Signature Series. This is with hopes that my vehicles engines will will last a bit longer. Thanks for providing a superior product. David B.

I use this in the 7.3 Ford Godzilla Motor. I prefer the added protection of full synthetic over the Motorcraft oil.

I have starting using the 0-30 instead of the 0-20 due to the miles in my truck. Amsoil is a superior oil after doing oil analysis. I will continue using!

I always and only use AMSOIL in all my vehicles. It's a really good product; I'd recommend it to everyone.

Fast delivery, this is my 3rd oil change with it. I love the product.

Once you have used this product, you will never settle for anything less and you will waste time searching for anything better!

I have been using this product on my 2017 Subaru when I first purchased it brand new. This is an excellent quality product motor has always run smoothly and without any problems.

Engine runs quieter and has improved performance and gas mileage compared to Mobil 1

Have been using the same oil in my wife’s Durango for years it’s a 5.7 liter just had head off at 183000 for a lifter inside of engine was very clean. The 5.7 has always ran smooth with the oil as well I use to trade cars so soon it didn’t mater to me but now days we keep them .

Amsoil synthetic 0W20 is the best oil iI have ever used. My first break in oil change was fantastic with virtually no metal on the magnetic drain plug and filter. I have changed it again at 3000 kilometers with the same result. Highly fecomended as a kit with WIX filter.

I have used only Amsoil for years!! Highly recommend to everyone!!

This is great oil and well worth the money!! There is no oil made like Amsoil!!

The product exceeded my expectations.

Jeep engine seems to run smoother & quieter than before. Wll probably change @ 15K instead of pushing it to 25K. Definitely beats changing oil in December, January or February

Slightly better gas mileage. Small tuck,tick engine noise gone. Seems to idle smoother. Like the added protection it gives as gleaned from Ai reviews. Will update review in the winter

This is the best, why settle for less. Lives to its promises.
