I had previously used Castrol, Mobil 1 and Valvoline synthetic oils and had no issues after 5,000 mile per changes. Since using Amsoil I'm able to extend the miles between changes with better milage and smoother engine idle. Amsoil sync burns cleaner and not as dark after 9.500 miles then the others did after 5,000. I have always used Wix extended life oil filters on all my vehicles...

Shipping was fast, great product! Worth every penny

Used this oil now for 4 years. Only have changed the oil twice. Excellent gas mileage in my F150 and motor runs quite.

This stuff is great, I was running different oil before I switched to AMS BOOSTED. Then with my car build I went with the Signature series and it’s preforming amazing.

always have used full synthetic motor oil,1st time now using amsoil. will keep tabs on overall performance and check dip stick regularly. can get hot here regularly and cold too. so far works well with ford 2.7L eco boost engine. also always use best 91 octane fuel. more to come,lets drive it

Excellent oil

Good product holds up under extreme conditions

Low mileage 5.3 in a GMC 4x4 crewcab. Because of direct injection i installed a catch can to help prevent intake valve carbon deposits. Previouly had been long time Mobile 1 user, with Mobile one i was draining several ounces of oil/blowby byproducts between oil changes. Since i changed to signature series amsoil there has been practically nothing in the catch can. Very significant in my opinion. Additionally this has been occasional towing of my 26ft boat. Im impressed and pleased and will be changing over my other vehicles to Amsoil as their oil changes come due. Thanks for a great product that is a cut above.

The signature series is the best of the best !!!

Changed the oil on my wife's 2005 Toyota 4runner and she noticed how much smoother the engine ran. We have over 400k miles and it still runs great. Always use AMSOIL!

Good oil.

Awesome

There’s no oil out there that compares with Amsoil. I use it in every motor I have. And in the chain saw gas too. All the motors run Very well. If your considering trying Amsoil, you’ll be Very Thankful you gave it a try. Your motors will too. It’s the Best oil out there.

I've been running Amspil for about 10,000 miles. The oil looks new!!

I have been using SS 0W-20 in my 2010 Lexus RX350 since I bought it new. I'm up to 120,000 miles with no hint of an engine issue. Based on using SigSeries oil in my 2000 Toyota Tacoma (215,000 miles), the Lexus will last forever!

So far I feel the different driving my CRV. Gained more mile per gallons. I run very smoothly and the protection is there. Thank you Amsoil

This the best oil for you tubo or Hi RPM vehicle I will recommend this product all day long because of the quality and the service for this product

YouTuber Project Farm pitted Amsoil against several other top brands and Amsoil was the top dog in nearly every category. Do I wish it were cheaper? Yes. I'd use it my commercial applications as well, but as it stands this oil is really only worth using on a vehicle you really care about and plan to keep for a long time.

Works great in my 2.5L EvoX Mivec still works. Amazing oil

I have used this product in my 2014 Mustang and in my 2017 Taurus. Both cars ran very well and the inside of the engines look like new, at around 80,000 miles. I change my oil and filter at 15 to 18 thousand miles and have never added a drop between oil changes. I plan on keeping the Taurus to at least 200,000 miles.
