Customer Ratings & Reviews

I for one only use Amsoil. This is my first time using this specific one and man I feel the difference. My engine is running even smoother than before on this aggressive tune that I’m running. 100% recommended.

I wouldn’t trust anything, but Amsoil in my Land Rover or my Z06 Corvette

Switching to Amsoil Signature for my wife's 2020 Ford Explorer ST was the beat decision I could have made. Since changing, the engine is noticeable quieter. It seems to run smoother and with the extra miles I get between changes, actually makes this oil as affordable as any lesser brand. The added protection and peice of mind on a very expensive investment makes this my go to choice from now on.

Very Fast shipping rate 5/5 recommend

Change the oil in my 2025 GMC Canyon Denali noticed the difference wright of way . Engine runs quieter more pep.

Ever since using Amsoil my vehicles engines are running smoother and cleaner in the valve system.

Switch from violin to Ames all you'll love it can feel the difference in the gas pedal temperature stays cooler for some reason. I've been using Valvoline. over 30 years I switched and I love this oil

Amsoil is in all my engines - Truck,SUV, lawnmower, Snowblower 👍

Apparently ups damaged the box and returned it. Company did nothing to send me a replacement until I called them. They offered no discount or anything to make it right and now I must wait another 5 days to get the oil. Will not purchase from them again, mainly do to the poor customer service

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

Have been running this oil in multiple vehicles for years. Over 500k between them all, not sure if it's the oil, but no oil leaks and not a odd noise to heard. I matched the oil with the Amsoil filter, 1yr oil changes save a lot of time when you have a bunch of vehicles to maintain.

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.

Been using Amsoil products for over 25 years. Never had an issue with them, until the last couple of years. I've noticed on 7,500 mile oil change intervals that the viscosity drops out of range. 4 of my last 5 oil samples tested in 2 different vehicles have returned lower viscosity than it should be. My last sample only had 5,800 miles on it and it was lower than it should've been. Making me wonder what changed.

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.
