The best oil money can buy! I use it for all of my vehicles. I would not use any other oil in the market. Try it, you’ll like it! You just might switch over from the oil your using now.

I’m using it in my Challenger Hellcat I love it I will always gonna use AMSOIL in all of my cars! I never gonna buy any other kind of oil ever!

I have used nothing but Amsoil in my vehicles once I buy them and my wife’s Jeep is no exception. I expect my vehicles to preform well and in doing so I trust Amsoil to keep them running their best.

Been using Amsoil since 1975 when I first became a dealer in Berkeley, CA! My car calls for 5W30, but due to a slight bit of oil consumption at 200,000 miles I went to 10W30! My Toyota (bought with 140,000 miles on it) is purring like a kitten... :-)

I change oil once a year and only use Amsoil signature series. With the heat and humidity down here in Florida this gives me the extra protection I need in all my vehicles.

After researching Amsoil for a few months, I made the switch based off of technology and reviews. Ordering was easy and shipping was quick.

For many years AMSOIL has been my go to oil for performance trucks and cars. I have tested other oil brands through analysis via sampeling port at 5k miles and 30 minutes after engine shut off. AMSOIL has proven better engine wear protection to competitor brands. All my vehicles have over 150,000 and still going strong. Diligent maintenence and quality products equal years of trouble free use.

First of all I’ve used Amsoil since 1988 and couldn’t be happier with the product line they offer. I’ve run it in race sleds turning at 10,000 rpm, my boosted mustang, motorcycles, dirt bikes side x sides etc. I’m not just talking this product I’m talking all products I’ve used in different toys for approximately 32 years and amsoil has always always held up the absolute best under extreme conditions. Now let’s talk about the people at amsoil..... outstanding customer service, shipping is very fast and accurate and always a pleasure to deal with over the phone. I would highly recommend AMSOIL to anyone that wants that competitive edge and keep you toy running smooth. Thanks @1bads550

This is all I'll use in my vehicles. Family owned and American made plus they're the best. It's a no brainer for me. Try it and you'll never look back

I love AmsOil. It keeps my engine running clean and smooth. I’ve been using it for almost 5 years now and it doesn’t disappoint.

I have been using Signature Series 5W30 in my 2007 Toyota Prius for the last couple of years now and I have noticed a marked improvement in overall engine performance as a result. The engine used turn on and turn off rough when shifting in and out of electric drive mode. Not since using Signature Series have I noticed this issue. The engine runs and idles very smooth and have seen improvement in overall MPG. I would highly recommend this product for anyone looking for a high quality motor oil to help their vehicle run as smoothly and efficiently as possible!

I use this oil in the wifes Honda, they call for 0W20 as it is critical for oil pressure in tight places on start up. This oil does that and protects when Hot. Good stuff.

The oil really holds up, I never have to add at the end of 5000 mile oil change!
