Customer Ratings & Reviews

As a mobile sharpener, I put a lot of miles on my vehicle. By using AMSOIL, I have peace of mind that my van will run smoothly for a very long time. I highly recommend this product!

I use product in my 2016 2.4 litre canyon . It's a great product but my engines seems consume some of it . A litre on 5000 km disappears through exhaust .

Going on 7k mile oil change...oil still looks new... Car performing well. Amsoil is the best of the best.. you get what you pay for...no more mobile one or Royal purple for me ..never again.

Long lasting great protection

I be using amsolil in all my car back front the 1990 I never have any engine problem. All my cars run good and I put a lot of miles and the engine always run good ! I have 2014 Acura MDX I be using amsoil when the car make 7,500 and the car still running like new !

When servicing my vehicles with Amsoil Sinature series oil, the dealer always comments on how there are no leaks. It also increases my trade in value when I upgrade. Never a complaint.

This is hands down the very best oil you can buy. Been a faithful Amsoil user sense 1982. The very best protection there is

Using this Motor Oil puts me at ease and you can depend on it to so it's job. I have used Ams Oil for years now and it keeps your engine running as quiet with nearly 200,000 miles on it as the 1st day you got your car. It definitly keeps your internals sludge free. This I have experienced first hand. Oil pan and valve cover removal.

I use Amsoil products for all of my lubricants in all my vehicles and equipment since 2015. I am very pleased with the performance and protection and am convinced these products are second to none. I bought an F-150 in 2015 that sounded like the transmission was ruined, put in an other brand of transmission fluid and nothing changed. I then put in Amsoil transmission fluid and it immediately fixed the problem. I haven't looked back since. I know the products might be a little more expensive then some, but they are the best. Thank-you for putting out a great product that is a valuable investment for hard-earned money!

Great Product, run the small engine oil in my Kohler whole house Generator.. runs cooler , quieter and I know I'm using the best oil between change intervals... also I have a 2005 F150 with the 5.4 Triton Engine.. everyone knows about the problems with these motors.. switched over to Signiture 5w-30 a couple years ago.. runs a lot quieter , cooler and just seems to purr .. yes I know the motor specs 5w-20 but it does honestly run better and have had 0 issues with the motor.. ... Bought truck new in 2005..

Use it in everthing

I use Amsoil because it is the best oil. I recommend it to all my friends.

I have been using Amsoil oil and filters for about 20 years and in my opinion they are the best on the market. I ran a 2001 Chevy Blazer 25K miles between changes with absolutely no problems and it was still running perfectly with 109K miles on it when I sold it.

Had royal purple in my wife's Dodge Durango 5.7 V8. If it sat for a few days and I started it I could hear a valve knock that lasted a few seconds and sounded bad. I've had this amsoil in with amsoil oil filter and I can leave it sitting for a week and start up sounds completely normal. I can tell I'm getting proper lubrication and I trust amsoil because of it. Also put it in my Cummins diesel and it's smooth as glass as well. I think I'm amsoil for life.

As great as the oil is for my personal vehicle and as much as i love it, i would not recommend or use it again for a Heavy duty diesel semi truck. Ran it in my peterbilt for 20K miles and by then I ended up burning through almost 2 gallons of it which is excessive compared to what i used before ( Shell Rotella T6). It was the same viscosity on both brands but AMSOIL seemed a lot thinner at 20K miles then shell was.

I use this oil in my 98 wrangler works great

She still beats a GT Mustang after 14 years, running Amsoil since the start

I run this in all of my vehicles. It is worth every penny for sure! You won't regret buying this.

Phenomenal product that is worth the price. Yes it is expensive initially, but it has stood up to some hard usage with issues. 20K oil? Bet on it!

I use Amsoil, dual bypass oil filtration, and test lab analysis to support extended oil changes. Lab analysis has shown me I can run almost 40K miles without changing oil. I sometimes drive 1000 miles a week or more for my job; and monthly oil changes simply don't cut it. Amsoil does. I spare not the miles and trust Amsoil to go the distance; I have independent lab analysis to demonstrate it.
