Customer Ratings & Reviews

AMSOIL is the only oil I have used in everything since 2008. Lawnmowers, Harleys, and all other vehicles. About 12 years ago I bought a 2003 Toyota Sequoia that had 145k miles. First thing I did was change the oil to AMSOIL and only changed the oil every 10k miles (also used AMSOIL filters). Over the 10k intervals I may have to add a quart between changes. It now has 450k miles and the motor has never been touched!

This is my first time using this oil. I am extremely pleased with the results. My gas mileage has already increased by .2 mpg and I would not be surprised if this will increase a little not over time. I do not plan on using anything but AMSOIL in my vehicle. This is a high-quality product that is definitely worth the cost!

Is an exelent product.. Keep my transmission working in perfect condition and shifting smooth. 100% recomended!!

Truck would idle rough and stall out. Would crank up just fine every time and never ran rough while driving. Have read that it can be from all kinds of causes that are expensive to repair. About 1,000 miles in to this first oil change and it has not stalled out yet. In conjunction with an amsoil oil filter, WIX air filter and PI injector cleaner.

A noticeable and immediate reduction in the ticking noise in my engine. Car has 180,000 and the noise has steady grown over the last 60,000 miles. Have 1,000 miles on the oil change and the noise is still much improved, almost gone in fact.

My 2001 Chevy Suburban has over 250000 miles on it. This was my first time using the product. I will tell you , I am very impressed. My truck runs a lot smoother now

Excellent product as always

I switched to AMS Oil in my bike awhile back and finally decided to switch in my Subaru as well, the car idles smoother and is noticeably more on the quiet side. Highly recommend to anyone looking for a better engine lubricant!!

I have used Amsoil for a while and what can I say? My cars just start every morning and take me to work or wherever I want and then back home. It's all I need and care. I trust Amsoil due to their heritage and a lot of positive reviews. Are they the best? There were some tests done online against some reputable competitors ànd always came first. I just trust them.

I’ve been using Amsoil in my 2019 Jeep JL V6 3.6 since I’ve owned it 3yrs now. It’s at 87k now and I decided to go with the high mileage oil just because the history of the motor and it’s a daily driver.

I have done oil analysis with Amsoil, and it really does go longer than 10,000 miles. Great company, great service.

Been using amsoil since day one. 500 miles dumped manufacturers oil and replaced with amsoil every 8,000. The trucks now had 94000 and we use the high mileage. Trucks quiet and runs strong.

After the oil change it just seems to run a little more smoothly than normal

As people complain about some turbo motors using oil I’m At 45000 with my engine no leaks no oil consumption no complaints It’s all because I use AMSOIL It is just that simple. best oil ever

I've been using Amsoil for years! Thank you for a well-made, endurable and engine life-lengthening product!

I have been using Amsoil product since 2003 and have been totally satisfied with them ever since.

Quality product. Car runs smoother and cooler. Definitely a noticeable positive change in the performance of a car with high mileage and commute.

F150 5.0 is happier and quieter with Amsoil 5w30

Top notch product. Love Amsoil, slowly transitioning all my vehicles over to it this year.

Recently switched all of our vehicles at my home over to Amsoil. Two Hondas and a Chevrolet pickup that all take 0W 20. I paid for the membership so the cost of the oil is actually pretty decent for how good the quality is, I stocked up on quite a bit to hopefully cover our oil changes for the next six months or so. I put a lot of miles on my Honda so I already completed my first interval on my 2014 CRV. I dumped 4.6 quarts in and 4.6 quarts just about drained out, so I can at least say over 4000 miles I didn’t lose any oil. I try to keep all of my vehicles for a very long time, so I have no problem paying a little more for the best oil, but honestly, if you join their customer program, with the discount the oil really isn’t much more than the stuff you would pick up at the parts store
