Customer Ratings & Reviews

Amsoil keep my engine around 25 degres lower, making a huge difference in confort for me and longevity of the engine itself. Dont even need an oil cooler, 2002 RG stage 3

This is the best oil period. Worth every penny just for the peace of mind you get with running the best oil there is. Project farm (on YouTube) did multiple tests against all the top brands and Amsoil came out on top. Also it's the easiest bottle to pour.. I run it in my Harley, Cadillac, and all 4 of my heavy duty diesel work trucks.

In the past three years I ordered from Amsoil I keep getting lost of promotion and free stuff in my email but never got noting with my order ??

Have ran this oil in my bikes for years now and drain plug magnet always has little to no debris on it just from using this brand.

Great products quick shipping & I can't complain about a thing

High quality products in one convenient kit.

The one and only issue I have with this product is the oil filter. I wish for a design that a traditional filter wrench is not required. On the Harley Touring bikes it’s a pain to get filter off. Hate to say it but many will use the K&N filter due to the hex requiring a socket. So much easier

Compared to other oils, not a lot of discoloration due to thermal breakdown. Reduces engine noise.

My neighbor turned me on to it.He checked the temperature of his oil from the other brand and then checked it with AMSoil.The AMSoil was 25 degrees cooler and my bike likes it too.I will stick with this until something better comes along.

THE BEST OIL ON THE MARKET !!!

I've been using Amsoil 20w50 on my Harley for 22 years now. Use it for the Motor, Transmission and Primary. Very satisfied with this oil!

I used to only run the purple drink in my bikes. But I'm not an amsoil guy now.

Fast shipping. All three holes changed and one ride on the oil. So far so good.

I have been using this oil for decades, for as long as I can remember and will continue to do so. As a preferred customer, I now save quite a bit of money on my oil changes every year - I use AMSOIL in my 2 motorcycles, my truck and my boat.

The best oil and filters to be used on a Motorcycle Would not buy this type of oil from anyone

Justin Peszko, I highly recommend. Great customer service. 2 orders exactly what I wanted. Thank you Justin! Will definitely order from again! As always Amsoil is top of the line product for all your needs.

I have been using Amsoil products exclusively in my three Harley-Davidson‘s for the last four years. I noticed an immediate difference when using their products in the MA motors. Transmission shift, smoother engines, run, quieter, and clutches operate smoothly.

Been doing Amsoil 3 hole oil changes in my Harley since 2012. No muss, no fuss, no mechanical failures.

Ordered the kit online from amsoil. 4 quarts, a filter, three paper funnels, and three shop rags. Did not receive the oil ring. Luckily the old one was ok. I would order the kit again. It beats using dead dinosaurs.

Everything you need along with O ring.
