Customer Ratings & Reviews

Using this superior oil allows me to change my oil and filter only once a year with the confidence knowing my car is well protected in all types of weather. Thanks Amsoil!

I can't believe this oil would give significant change in the performance of my Honda Accord 1991. My car runs so smooth and quiet. It also gave me extra miles per gallon. Exceptional product!!!

I have been using Amsoil for close to 20 years now. I have 170,000 on my Dodge Magnum, and still going strong because of using Full Synthetic oil. Fabulous Product!

Started in 1974 love it never lost a oli part I have

Great oil.

BEEN USEING THIS PRODUCT FOR SEVEN YEARS ON MY CHEVY IT HAS 249000 MILE AND IT STILL STRONG RUNNING EVERYTHING WORK GRAET.

Been using Amsoil for a long time and in my opinion it’s the best and only oil to use in your engines.

Best oil on the market. My truck has over 250K miles and still going strong. Does not burn oil and the tailpipe is super clean. Will never use anything else.

Will take a 3000 mile trip in may. So far no issues.

Seems to make my 2002 Tacoma run smoother. Pricey but would recommend if had discount codes.

It’s becoming expensive but I believe it is still the best out there. If you can afford it buy it. No regrets.

Product as advertised, shipped as expected, received in tact & without issues.........you get what your willing to pay for !! : )

Not an engineer, yet I believe this to the the best oil I can buy for my higher rpm street car.

So many years I’ve used other oil brands until I found amsoil I’m glad I’ve found the best oil for my vehicle amsoil has the best products I love it

I use and change this oil, once every year, in all of my small engine equipment. When changing the oil, I always mix 80% of this oil along with 20% of Duralube Engine oil. I believe that this oil is far superior to any non-synthetic or synthetic oil that is currently available on the market today.

I use and change this oil every 15,000 miles in my truck. When changing the oil in my truck I use 4 quarts of this oil and add 1 quart of Duralube. This combination/mixture seems to keep my engine running smooth. My truck currently has 150,000 miles on it and it doesn't burn or use any oil.

Engine work perfect
