Customer Ratings & Reviews

I use Amsoil products in my truck and my wife car. I started using Amsoil products in my race car many years ago and had such good luck with them I have been using them in anything I own with a gasoline engine. My truck has over 200,000 miles on it and it runs like new. We use my wife's car for road trips and I always ride with confidence in Amsoil products. I would definitely recommend Amsoil to family and friends..

In work&personal vehicle.Work car approaching 300,000 miles-Starts easy in old weather-improves gas mileage-don't have to change every 3000 miles as you have to with conventional oil-can't think of anything negative

My engine is really quiet now. That tells me that Amsoil is lubricating the engine in a way that the other oils can't. I changed all the fluids on my 2017 Chevrolet 2500 HD 4x4. Fuel mileage is up and vehicle noise ( engine, transmission, transfer case and differentials ) is down. it truly makes a difference. I've also switched to Amsoil in wife's 2017 Ford Explorer, my son's 2015 Ram 1500 and my 2015 Tahoe Q7i SF boat.

great stuff

In my motocycle

The to go motor oil for all 0W-20, 0W-30, 5W-20, 5W-30, 10W-30 applications except europeans.

I only trust Amsoil in all of my vehicles.

very good

By far the best motor oil I've used!

We Transport trailers with our pickup and run only Amsoil in it. Love the extended oil changes, especially since we run so many miles. Because of the ability to run more miles on it, it actually is cheaper to run Amsoil. Wouldn't run anything else!

Use it in honda crv.Great oil. Long life.

A couple of years ago I had my 1998 Chevrolet Silverado in the shop for an intake gasket repair. About mid-day I received a call from the repair shop asking me what kind of oil I ran in the engine. They were amazed as they told me they had never seen an engine so clean inside. I told them I had been running Amsoil in the engine for the past 1.5 years. I had heard of Amsoil for years and talked to a diesel mechanic a few years before and he ran Amsoil in everything he had. I figured if a diesel mechanic ran it in his vehicles, motorcycles, and lawn equipment it was good stuff. I have not been disappointed, I immediately noticed easier cold starts and better gas mileage in my vehicles. With the miles my familiy's vehicles travel, a once a year oil change with the extended life best synthetic oil on the market is a convenient and cost effective solution for ensuring my vehicles engines are protected with great lubrication. And the added bonus of creating less waste for our environment is big for me as well. Convenient online shopping and dependable delivery put my vehicle's lifeblood in my hands within days of ordering it. Love the product and will be using it for years to come. Dale

I use Amsoil oil for everything I own car pick up motorcycle lawn mowers weed eaters I wouldn't use anything less The best is Amsoil oil.

its a great oil I have every use in my cars!

AMSOIL is in every engine I own!

I have been an AMSOIL user for many years, and as a mechanical engineer know the value of proper lubrication. When you know a company is using the best additives, and the best base stocks for their oil, the choice of where to buy is easy. In the final analysis, AMSOIL is a bargain compared to other brands.

I have used the Signature series oil for years. I like having the protective properties of the oil with extended change intervals. I have one vehicle with over 225,000 miles runs great and uses zero oil between changes.

Use this in my Mustang GT....won't use anything else. Lots of debate as far as what's best but this is my favorite.

The day I bought my 2005 F250 4x4 I brought it home and drained the stock oil and refilled with 0W20 amsoil and amsoil oil filter. Since that day my truck has never seen any other oil or filter. My truck is now 13 years old and it runs like the day I bought it. I change my oil once a year no more no less ! ! !

I have tried every synthetic oil over the years.Then I tried Amsoil signature series 5w-20 in my 2017 dodge Ram with the 5.7 hemi.Notice a big difference in smoothness and performance,like pouring a few energy drinks in the engine!!! I change my oil every six months, I wont be close to 25,000 miles but if I go over six months I know the engine will be okay. I have changed my oil with other synthetics that claim they can go 15,000 or one year, I changed mine at 6,500 and it was black and smelled burnt and was already starting to sludge.You won't get that with Amsoil. It cost a little more but it's well worth it !!! If your going to keep your truck or car for a long time Amsoil is the way to go,If you lease every two years don't bother.Give it a try it's THE BEST!!!
