Best oil hands down.

Nice product

I used the oil in the past and decided to become a member the oil makes my engines run smoothly and helps with little better gas mileage definitely recommend using the oil to find out for yourself

This oil--Amsoil 5W30 synthetic motor oil--is the best! My Camry's odometer reads more than 300,000 miles, and I've been using Amsoil synthetic oil in it since I bought it in 2004 with 71,000 miles on the odometer!! I very highly recommend Amsoil synthetic motor oil!!

Best oil for my 2019 Alfa Romeo. Great company to order from. Quick shipping and delivery. Highly recommend

It hit me one day, when I realized the founder of AMSOIL had an aerospace background, he got the name from aerospace standards for all types of materials: A erospace M aterial S pecification. That's what sold me on the product. Thanks Al!!!!

Great oil!! Highly recommend!

I’ve been using amsoil since 1990. I would not use anything else.

Great product and fast shipping, nothing compares to the quality of amsoil!

I have been using 0w40 in my ram 6.4 gas enegine since new. Currently 67,000 miles and no hemi tick. Fingers crossed this helps prevent premature failure.

I've been using this oil in my 2002 porsche for the past 5 years engine runs super smooth and has more power. Since then I've changed all the oils in my cars to amsoil.

Merveilleux , mon moteur est heureux !!!!

Best oil on the market

I had a noticeable amount of noise on start up with the factory oil after changing the oil using amsoil signature series 5w30 it reduced the noise by 75%

Amsoil products protect and keep my engine running good!

I saved money by ordering by gallon instead of quarts.

Amsoil fan

I love the protection it provides and it lasts longer then regular oil. Extends the oil change times.

This is the only oil I use in my ‘06 Jeep TJ. It’s the best oil out there in my opinion.

Signature Series is the crème de la crème of amsoils line. I run it in the wife’s Ecoboost explorer and it’s phenomenal. We have had several oil samples before and after switching to this oil and the samples since running this oil are always in the green. It’s cleaned in the inside right out with their detergents and I feel great knowing at least on the oil end of things were doing it right.
