Customer Ratings & Reviews

Great product

We use this for all of our air cooled engines

Have carburetor 95 Evo Electraglide. 88,000 miles. Change oils at 5000 mile interval. Sent in oil sample in October. All tested out good.

Excellent product

Use this in my 2015 Harley from the time I got it new.

This is a great oil for my M8 engine. I have had no issues with it and appears to hold up as well as any Harley oil for less cost.

I have been using Amsoil 20W-50 in my 2004 Harley since new. I will continue to use this for my oil changes .

I use Amsoil in everything I own , car ,truck and motorcycle

Since adding this to my crankcase compared to Harley Davidson SYN3 it is quieter when engine is running.

The only oil I purchase for all my "customer" LOFs and for my own bike as well.

One week ago and approximately 450 miles I installed a Fueling camchest. While removing the necessary parts felt the oil had lubricated these parts in such a way that their was no wear signs on any of the replacement parts. The last 4 oil changes where done with Amsoil and the bike has 25500 miles Highly recommend.

Love Amsoil

Will continue to us Amsoil products in my 2020 Harley Davidson Road Glide. Awesome customer service as well!

Been using the 20W50 in all three holes of my Harley. No complaints in 22K miles, seems to work fine in the primary, transmission and hot rod, (cammed 131"), motor.

Hands down the best oil. Wontvrun anything but AMSOIL

Really Good Oil,i use in motor and transmission for my Big Dog K-9.

I use AMSOIL for the superior protection

Amsoil,or as others call it snake oil holds up to the conditions I put it through long steady rides in hot weather,onto town and stop and go traffic ,have Sent it on for to be checked out for motor e wear and other signs of wear always comes back favorable. I tell all who will ask good stuff get some

My Harleys run cooler n smoother in the engine plus power lever feels more torque … I run nothing but ,
