Customer Ratings & Reviews

Have been using this oil since 2005 in my truck. 2005 silverado 5.3L tuned and full bolt ons. I had used it prior for 3 years in an older truck I had. Very confident with Amsoil that I've been changing the oil in the silverado once a year for the past 11 years. I also have a 2014 and Amsoil is used in it as well since the first oil change was due. Back to the 2005 truck. Reason I told you its tuned... many people know how a tune gets your engine a "little" less life. Well, I have had to change out the valve cover gaskets twice within the 11 years I've owned it and as far as valves and heads. They're like brand new. Once a year change intervals. Truck has 140k+ miles. Amsoil has kept it running smooth since day one. Can't beat that!

I use it in 2008 Taurus and a 2015 Ford Explorer. I've used it in the Taurus since 3000 miles and it now has 115,000 miles on it and have had no engine issues and still get 22 - 25 mpg. I bought the Explorer new and have used it since the first oil change and it now has 41000 miles on it. Love the oil ! I would recommend it to anyone looking for a high quality Synthetic motor oil.

Best oil for cold weather start ups. It increased my fuel economy from 27 average to 29

Amsoil synthetic is a high quality oil. I use it in all my vehicles. If you want superior oil with extended oil changes, amsoil is the way to go.

Use it on my daughters Mitsubishi SUV.

Car runs great with this oil

I have been an AMSOIL fan for two decades and continue to be super impressed.

I just started using oil and noticed a difference in the operation of the engine within the first change it is smoother running and quiet

I run this oil in a 1993 Dodge W250. This oil works great in this old truck. I am very happy with Amsoil, it is all I run in my equipment.

I use Amsoil Signature Series 5W-20 Oil in my 2014 Ford F-150 for maximum protection. The engine is the 5.0L, and it runs very well with this oil.

amsoil is all i use. truck, car, scag, polaris, and harley. the best.

So far it's been nine months since I changed the oil on my daughters cobalt and Sentra , and the oil is holding up extremely well . recently replaced it on my wife's 2013 Altima and my dad's 2007 Dodge ram 1500 . So we'll see what holds up as just as well has on our cars . I use the European formula on my BMW and it's awesome . Actually better than the regular TwinTurbo oil and just a tad better than the M formula

I use nothing but AMSOIL for my Toyota Tundra with 162,000 miles, mostly all local driving, use a 15,000 mile filter, and my truck doesn' t lose a drop oil. Great stuff.

Excellent product. Will continue to use and purchase.

Put oil and filter in my son's car, he forgets to check oil like he should but with 4 quarts of Amsoil, is better then 5 quart of regular oil, so I know his car is covered.

I use only Signature Series 5w-30 in my 2008 Toyota Sienna and she purrs like a kitten. This stuff is guarantees for 25,000 miles even though I have never pushed it that far but believe it will stand up to the miles as instructed. Used Mobil 1 products for years but found Amsoil and have never looked back. Fair price, great shipping and I enjoy knowing that I am using the best. Turned on many of my friends and co-workers to Amsoil and they have all bee amazed by the performance of the oil. One person in particular had a Chevy Suburban with nearly 200,000 miles on it and was contemplating dropping in a new engine due to some form of tapping noise. I introduced the person to Amsoil and was pleased to hear the noise had nearly disappeared and his vehicle is running like a race horse. Thanks you Amsoil for making superior products for those of us who cannot afford to buy new vehicles every couple of years. If you want your stuff to last, Amsoil oil is the way to go. Just give it a try and you will not be disappointed.

Advanced fuel economy.Superior engine protection.Fully synthetic motor oil.

have been using exclusively for five years it is the best performing synthetic oil you can use

Hands down best oil around.

Could tell the difference the first time I changed to this oil. The van runs smoother and uses very little between changes.
