Customer Ratings & Reviews

I’ve been using AMSOIL for many years in all my vehicles and never had any problems. Highly recommended.

I've been using this product for years, and every time I have done any maintenance on my vehicle l'm very impressed with the cleanliness of the internals of the engine.

Great products

Been using for many years. Love the quality

Amazing oil at a great price!

Late Fall oil change in 0W30 protects even on below zero mornings and we do not have many of those here in Texas.

The oil is over kill for my 2.7 Toyota Venza ,but that's just me ,I like knowing that .

I use Amsoil 0w40 in my 2015 Challenger SRT392 along with Amsoil oil filter. I feel it’s the best oil for this car. I’ve been using Amsoil since 1999 and will never change.

Been using Amsoil since 1999 first in my motorcycles and then all of my vehicles starting in 2001 and have never looked back. It’s all I’ll ever use and Amsoil filters. Highly recommend Amsoil to everyone I know, but not all will listen and take advantage of the best oil in the business if you ask me. I use 0w30 in my Ram 1500 with a HEMI of course. And the same in my Jeep Wrangler JKU. LOVE THIS OIL.

The best oil money can by !!!

Huile de très haute qualité mon auto n’a plus ce petit claquement de moteur qu’il a toujours eu même si je mettais de la très bonne huile avant de connaître Amsoil

This is probably the best oil ever used in my engine.

I use 0-20 in my bmw x-1 suv, and 5-30 in my wife x-5 they both perform perfectly even the bmw service dept said excellent choice, this speaks volumes for them as they ate the best techs out there Roadshow Bmw memphis tn

I have used this specific oil for 15 years,now on my Z06, Cadillac and Ram.

Product arrived on time as advertised. Quality, ease of pouring and the clear liquid level gauge is a nice feature. The engine seems to like this oil as there is very little engine noise while running.

Have been running the Signature Series 5W-20 in my son's 2015 F150 with the 5.0 Coyote since we purchased it last year with 148,000 miles. Ran the AMSOIL Engine Flush for 15 minutes before our first oil change with AMSOIL because I want the best protection. Seems to run quieter and hope to get another 150K miles, running all fluids on AMSOIL...

Great product and customer service.

I’m running a 2019 Sierra with the 6.2L. My truck isn’t in the recall range, but I still want to have the best oil in it. And my employer pays for my oil changes. I don’t like what I’m reading about the manufacturer’s reasons for using 0W-20/40 in these engines (gas mileage). So I’m using a thicker oil. I’m seeing zero difference in mileage since I switched to this oil, which is good.

After 20k miles still good

I change it every year less than 25k miles and the oil viscosity still good
