Great oil it is what it suppose to do keeps the engine running smooth and clean for a long time..

I grew up on amsoil. My father grew up on amsoil. His father grew up on amsoil. I have been happy with everything I’ve gotten for my C6 corvette. Shipping time is unparalleled. Worth every penny if you love giving your car the best there is.

Delivered fast. Packaged neat. Used the funnel it came with. Now I have the peace of mind knowing I’m running the best that’s available for my truck.

I have several vehicles and always use amsoil. I have a car with 300000 miles. Amsoil since new, can’t even hear the engine run it’s so quiet! That says it all!!

I wouldn't use anything else!

Simply the best.

Best oil on the market

I have been using this oil in my Jeep Grand Cherokee since it was new, 97,000 mi later still runs great.

I only use AMSOIL products in all my vehicles. All I can say is if I put 6 qts in 5000 miles later I get 6 qts out. No other oil I have used does that

Took a little extra time to get the gallon jug, but I guess that means they sell enough that it's hard to keep on the shelves

I just recently switch to amsoil for all of my fluids and I absolutely love them and I can tell my truck does too!!!!

From all my research AMSOIL is the best period when it comes to oil. I will use it from now until I die for all my vehicles.

Best oil on the market change it every year on my 2014 Silverado Crew Cab LTZ 28,890 original miles

Same as before

I use this light oil in my Tundra 4.6L engine, and it seems to work well. Being 100% synthetic oil, really boosts my confidence in using this in my Tundra.

I have used this oil since 1998, and have been using the bypass filter system as well, with great success! My cars always rust out before the engine wears out. Two of my cars have had just under 600,000 kilometers and the engines run like new. They always start great, run great. Too bad the body rust destroys the cars. Winter sure is hard on cars.

I’m using AMSOIL for two years now and I’m happy with the oil quality and filters. Unfortunately many times they’re out of stock on filters but we try to work it out. Other than that is a great brand

Best lubrication products ever. I use Amsoil in all my track and cars. I changed my oil at 1,000 miles in my new RAM RHO with the Amsoil Synthetic oil, runs great.

Have never had a motor issue in anything I've ran amsoil in .

I have been using Amsoil full synthetic for years and it has proven to be a superior product
