Excellent product! Keeps my F150 3.5L eco-boost running smoother and cooler in the Summer, and no knocking during start up in the winter. The detergents in the oil really keeps the engine innards clean! I witnessed this along with the dealership, how clean the motor was during my timing chain replacement. The engined looked as if it was just assembled. I am glad I made the switch to Amsoil
Great customer service. Free shipping was a very nice bonus. The best thing is the quality motor oil that keeps my 2008 Lexus IS350 running great at nearly 150K miles. Thank you AMS Oil.
saves me around 3 extra miles per gallon so i end up with an extra 30miles per fuel up. car runs smoother.
Bottom Line
Yes, I would recommend this to a friend.

Excellent Lubrication

I have used many top shelf brands over the years but this my first time using Amsoil and I truly regret not making the switch sooner. The most unexpected benefit which I have experienced is an increase in MPG (the Hellcat needs all the help it can get! Lol) and slightly cooler operating temps.
I did all kinds of research into finding the best oil for my 4Runner. Out of all the torture tests I’ve seen Amsoil kills the competition! Do you pay a little more? Yes but it will be well worth for the life of an engine
Bottom Line
Yes, I would recommend this to a friend.

Works great in lawn mower, i don't know that my mower runs cooler or smoother but I've ran amsoil for years in other things and noticed things like operating temperature being decreased and other things so may as well trust it in the mower to.

Used signature series motor oil for 15 plus years. Vehicle runs cooler, and I average about one mile more per gallon. Worked well for over 250,000 miles on Nissan Maxima, Honda CRV and Toyota Avalon. Never had an issue.
I ordered a case of Signature Series 0W-20 Synthetic Motor Oil and when it arrived, it was short one gallon. There may be a delivery truck out there running high grade motor oil. I called Jason and told him what happened and they got me another gallon out ASAP. The oil is in the vehicles and so far so good. If it's as good as the service, I'm set...
Bottom Line
Yes, I would recommend this to a friend.

The only oil I can find that is full synthetic AND meets KIA's turbo- direct injection standards PLUS has a warranty to boot! All I use.
Used Amsoil on my old truck that still run strong when I sold it with over 240000 miles on it so I'm started using it on my new F350 starting at 3000 miles on it.
Bottom Line
Yes, I would recommend this to a friend.

I use it in one of my high horsepower LS3 engines that I have built. It nears 600 na horsepower at the crank and 500 rwhp, and it is a daily driver. Only thing I trust is the 5W30 Signature Series.
Bottom Line
Yes, I would recommend this to a friend.

Amsoil 0-20

I love this oil! I have an oil catch can to catch the sludge buildup and it hasnt catched any. I've been using this oil for about i'd say 3 oil changes since I switched from Mobil 1. Never going to any other oil. Superior protection, cleaner engine, better gas mileage...best oil ever! Amsoil is the way to go!
I've heard from too many mechanics and truck drivers how much longer engines last with amsoil synthetics. I don't drive much so one oil change a year with a filter change in 6 months is all I need.
