Great Product

Great oil

Excellent motor oil and delivery time... sometimes ships same day, and it's received the following day or two.. awesome product

Great oil! Works extremely well in my turbo WRX. I continue to change it every 4000 miles along with a filter, but enjoy the piece of mind that comes from running a top tier oil and not having to worry about oil breaking down with the excessive heat and ruining my engine!

Use signature series on other vehicles in past first time using this one. Currently on a vehicle that is a daily driver in winter

Switched to Amsoil 0w40 in my 2017 Colorado from 5w30. Engine rattle on start up went away and engine runs smoother.

Running this in my Genesis Coupe, as is a good buddy of mine. Engine is spotless under covers and the viscosity really goes the 25k miles(40k Km) even under pressure from a very hot Turbocharger. I also drive for a living in this car, so there is a LOT of stress on this oil. ZERO complaints. HIGHLY suggest running the engine flush before using this oil, and doing a change at 15k mi(24k Km) the first time, if you have an older car. This stuff will wash the buildup from the block like those viral pressure washing vids. SERIOUSLY good stuff.

I highly recommend all Amsoil products

Best motor oil I have ever used

Hi quality oil for my coyote engine

I only trust Amsoil to protect all my vehicles. In the Arizona heat you need all the protection you can get. Amsoil does that.

I use this for my customers vehicles. I use AMsoil for all of my personal vehicles, so I presume this is no different quality.

I've been a very happy AMSOIL customer for twenty-five years now. I trust everything that they offer. I can't recall ever trying an AMSOIL product, whatever it be, that wasn't better than what I had been using. Prior to finding AMSOIL I'd lost an engine using Mobil One. About a year later I bought a brand-new car so I ordered data sheets to study several brands of synthetic oils and I found AMSOIL to be the best. Over the years, I’ve come to believe that everything AMSOIL offers is the very best in the world. What many people may find an alarming thing for me to say is that AMSOIL products cost less in the long run. Their oils and fluids last and last. I change motor oil once a year and that works out to be much less money than using cheap low-quality oils and changing it every three thousand miles. Any oil requiring a change as soon as three thousand miles can't be any good for my car, so that would be wasted money from the onset. I own four cars and a heavy-duty truck and I love each of them so I want only the very best products going into them. I have no intention to ever try any other brands because I wouldn’t want to give up the peace of mind that AMSOIL brings to me.

Good oil - no consumption after 20k miles. Fuel economy consistent for all miles.

Extended life / mileage before oil change is required is good!

Been using Amsoil's synthetic motor oil on mini-vans for at least 15 years. Always worked very well, little content would reduce within use during a 20+K range and no oil temperature problems with running these vehicles during freezing or very hot days.

Switched again to AMS Oil after I watched YouTube Comparison Videos. It is really the best so far on the market. Also The AMS Oil Preferred program makes their products affordable now because in the past I Used to buy their products from AMS OIL dealers near me way more expensive. AMS OIL + WIX Filters is the way to go.

great oil, use it in a 5.7 hemi with Lucas fuel treatment (good combo for a quiet motor) Ordered as a "kit" (oil & filter) Brands of filter offerings changed on last order (Donaldson chosen) Really good filter company (even publishes operating pressure specs). Useless if it comes a month after the oil arrives!

I use Amsoil 5W-20 in my 2006 Ford F 150. I am the original owner and I have 135,000 miles on the truck with no problems. I trust Amsoil products.

This oil makes my Passport run smoother.
