Customer Ratings & Reviews

All I use in my vehicles are your products as my son . Your products are the very best .

Great purchase experience, and you can tell AMSOIL cares about the quality of their products right down to the customer experience and packaging. Not shy to make bold claims about their lubricants, and for good reason. Have replaced all oils I've gotten around to changing thus far in my new 2020 Ford Raptor with Amsoil products from the diff oils, to engine oil. I'm sold on the oils for the engine and diff after 3,000KM - smooth running. I spent countless hours researching the best synthetic oils I could find, and contacting guys at race shops who swear by Amsoil and nothing else. Sold ... lifelong Amsoil customer now, and what's great is the points system and the fact that I can order everything from lubricants, to oil filters, and air filters all in one order delivered quickly. Awesome. Highly recommend

This 5W20 SS Oil is the best long lasting Oil I’ve ever used! I have Two 2005 Ford E-250 Box Trucks and both have over 400,000 miles. I have noticed cold start chatter GONE! These trucks restart 10 to 15 times a day Thanks to Amsoil I look forward to seeing 1,000,000. Miles in the future. Life User Henry J

The best oil and filters you can buy.

When I started doing my own oil changes(10 years ago) I switched to this. in my experience my other maintenance costs have mostly disappeared.

I have used this for years. It has never let me down.

Great oil. Runs cool in my Subaru wrx. Extremely good cold starts. Even when I get on the car it sounds healthier

I have been using AMSOIL products for 39 years. This oil product works perfectly in my 2017 Honda Accord. The fuel economy improves when using AMSOIL. The appearance of any wear is minimal. There is virtually no oil consumption.

I have been using AMSOIL for 39 years. This is used in my 2018 Ford Expedition Max with the 3.5 liter, 400 hp engine. I tow significantly a 7000 pounds loaded trailer. Excellent mileage, 9.2 towing; 20.5 solo during travel. No oil consumption. Smooth power. Cool running. What is not to like.

Great quality oil. Project Farm approved!

great product will continue to use.

I've been running the Amsoil for only about 2 months in a Gen 5 4Runner and only really city miles. BUT after 4 years of using Royal Purple, which I have had no real complaints with, I tried teh Amsoil and have seen a difference. Not a huge amount maybe, but big enough for someone who does their own oil changes and was using Royal Purple. It's a big enough difference for me. Less knocking during acceleration and just smoother in general. I'll see how it does since it's recommended for at least two oil changes....

Amsoil has always been good to me. I change my oil every 5000 miles on my motorcycle. Also on three of my vehicles. Great products.I like their gun cleaning solvents also.

The name speaks for itself. Proven and tested (follow the science) to be a top notch motor oil. Its all I use in my street rod and daily driver.

My engine is immortal. My oil slightly ambered yet stil tacky and the American is only because of Amsoil too cleaning performance and the engine was cleaned with sea foam and drained but had sticsion build up some internal on engine now it’s shiny clean. Amsoil is the best

i've been using Amsoil for a long time on my semi truck and i like it ,then i decided to use it on my pick up truck too . So far one of the best
