Customer Ratings & Reviews

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.

I use SS 0W-30 in my daily driver '06 Mustang. Change interval once a year with an Amsoil filter. The oil flows like water but slippery to the touch. When the engine idles all you hear is the muted sound of wet valves, and when I punch it all you hear is pure muscle; no pings, no knocks, just a well oiled machine! That car sees only Amsoil products and has 86000 miles on it. I have never had to add a single drop of oil to the engine between oil changes, ever. Every week when I pull the dip stick the same 2 punch holes are wet with oil . . . i rest my case, this is good stuff!

Put this in two cars with over 150000 miles improved gas mileage by 10%

I have been using the Amsoil products now for about 4 years, first in my 1999 VFR800 then my Ranger and now my Nissan Frontier and 2012 Sante Fe. I am very pleased with their performance in my vehicles and in knowing I have the best protection for my engines. I also like the fact that I am using less oil annually and the extended oil change dates make maintaining my vehicles less time consuming. l would recommend these products to others for the time savings alone, it makes it a lot nicer to only have one oil change a year per motorized product vs. the 2-4 I was doing in the past for each vehicle. Buy the products, use them as specified and you won't be disappointed.
