Customer Ratings & Reviews

This is third time I’m using this oil for my sports car really impressed with the quality of the oil. Highly recommended

Love this oil. I use Amsoil in everything on the ranch; all of the vehicles, tractors, SxS, dirt bikes, everything. I have never had an issue caused by oil since switching over. I can’t recommend Amsoil Fluids enough.

Bought used RV w/14k and I knew that it was serviced, but did not have a clue of what oil is in it. Used Amsoil engine flush as as the start of oil change and after oil fill, two Amsoil Upper Engine Lubricant bottles, and two bottles of P1. After start and ten minute run, I stopped engine and checked levels, and restarted again. I noticed how much quieter the F450 V10 sounded. Much less than before. I love any and all of Amsoil's product's and highly recommend this one.

I have used other oils but Amsoil is the best!

My 2012 Corvette Convertible has over 115,000 miles and still runs like new! With other brands of motor oil, I was starting to hear those little noises that an older engine makes over time, and I figured that was just the normal cycle of engine life? I started to use this product the last two oil changes, and those little noises are gone! It’s like I poured in a new engine in the process. I wouldn’t use any other product on my Corvette, and I’m looking for many more miles to come.

I've used this product before in my sports car years ago but decided to use it again in our fairly new aging cars. I instantly noticed an increase in horsepower and performance and reminded me of why I used to buy this oil years ago.

I run a tricked out Jeep off-road. I drive it hard and often. Trust no other than Amsoil!

Try one time and your vehicle will tell you, what it was missing. You will feel the smoothness of the engine. This is a great product.

Oil works great.

Bought an ‘08 Sierra 1500 brand new, always ran full syn valvoline. The AFM started acting up and the oil pressure dropped around 170K. Switched to mobil1 with 1 quart amsoil and within 1k started washing that old garbage out! Had to change filter! After 3K, went full Amsoil change, and again, had to change filter at 2k, another 2k, and another 5k. Another full amsoil change and no problem since! Totally washed the internals out! Super cleaner additives for sure!! AFM and oil pressure problems gone at 193K and counting

I have used Amsoil products for the last 21 years. The oil is great and all lab test results prove that. Changing my oil once a year also saves me a lot of money.I average about 10,000 miles a year and when changing the oil it still looks and feels great.

So far this oil has been fantastic!!! Engine runs noticeably smoother and a noticeable increase in fuel economy.

I have a 2000 Silverado 5.3 started using amsoil instead of valvoline & it’s really quite running engine after using this oil. Use 0w20 in my other cars and have no complaints. Very good oil!!

As always my first oil change will always be Amsoil

No problem
