Customer Ratings & Reviews

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.

I use it because the additive package is so robust, it can handle the severe service manner in which I use my Explorer. Combined with the Amsoil Oil Filter, I can go 15k miles or 1 year, even under severe-service use.

I use Amsoil 5W30 Signature Series in all 3 of my vehicles. After using the 10W40 in my motorcycle and watching the "White Papers" comparative study on 5W30 motor oils done by a reputable 3rd party test lab I was convinced that this was the best oil on the market. And they don't have other product lines to fall back on if sales don't demonstrate it is a quality product. The "White Papers" comparative study results really says it all. I am an Amsoil customer for life and have also convinced a family member who also happens to drive one of the vehicles in our family that you cannot lose but only win with Amsoil. He is sold on it too!

A little thicker for an older car with many miles.

I've used AMSOIL for 25 years religiously, and have done the research. (I also do analysis regularly) AMSOIL Signature Series oils are the best money can buy. Well worth the extra price over Dino oils! Also the best synthetic at any price! If you are not using AMSOIL, you are missing out!

I believe synthetic oils are great for any moving metal parts. No wear, No friction, saves money in years to come and makes my engines very dependable. My Pontiac now has over 260,000 miles and uses no oil, no smoke. Thanks to Amsoil!

Have just switched to Amsoil for my truck, so too early to review. I will say, though, that cold weather (-25c) starts are a breeze. If it performs as well as in my bike, it will be my go to oil.

I have a nearly 600hp 03 mustang cobra. Based on the used oil analysis I've done over the past 3 yrs, I've gone almost 6000 miles one interval and the oil didn't shear. I don't know if this makes the 0w-30 SS an outstanding oil vs other off the shelf oils, but I do know that high horsepower applications pls e greater stress on motor oils. So extract from my review, what you wish.
