Engine runs smooth and quiet. Never an issue. Products are delivered quickly and of top quality. Every engine I have run it in from Corvettes (5w-30 Sig. Series), to daily drivers (0w-20, 5w-20, 0w-30, 5w-30 all sig. series) and outdoor power equipment (small engine 10w-30) I have been impressed. Smoother, quieter, oil temps. slightly cooler and longer drain intervals make it worth while.

For my first time ever buying and using amsoil, I've got to say, I'll probably never go back to anything else again. Best motor oil I've ever bought!

My engine ran sooo much smoother. This is my first time using it, and i won’t ever use another oil. High quality for sure!

I've been using this oil for over 10 years in all my vehicles. One of my Hondas now has over 453,000 miles on it. I change the oil every 15k miles (due to the oil filter interval limit) and my car's engine is in Excellent shape. Highly recommended.

Have been using the Signature Series for a long time as they protect and extend my engine's oil changes. Never an oil protection failure when you use the best.

I absolutely love this product. The signature series line from Amsoil sets the bar for premium synthetic oil. I will never settle for anything less. Try it out, you won’t be disappointed. I guarantee it.

Best oil you can buy

The GT500 has a Ford B-Spec requirement, which in a 5w50, really limits you. This oil meets and exceeds the B-Spec, as it's C-Spec. Considering how little I drive this car, it will be an annual oil change far below the 25k mile range.

AMSOIL Synthetic motor oil is THE product for Texas driving conditions. My engine is cleaner.

This motor oil has been proving to be some of the best: I own a 12 Acura TL that's supposed to take 5w-30 was consuming soo much regular oil that I had to find something to slow down if not stop oil consumption OR at least slow it down, it didn't stop it but it definitely slowed it way down and make my car feel great

I have used this oil for many years now on our 2002 Toyota 4Runner and 2007 FJ Cruiser and it keeps the engines very clean and running well. Great performance and protection and no burning oil. I change it every 5,000 miles as recommended by Toyota which is expensive but worth it for the longer life of the engine and good performance. The 4Runner has 250,000 miles and the FJ Cruiser has 125,000 miles and both are running very strong.

As with any other Amsoil product, High Quality.

I am very pleased to be able to order quality products at fair prices that are delivered right to my door. Thanks Amsoil!

Been using this oil for over 40 years, been a engine saver over that time.

Been using Amsoil for over 40 years, it's the best.

Amsoil is the best oil I’ve ever used, it’s in all of my vehicles!!
