Customer Ratings & Reviews

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 ,

Good quality oil

I thought there was better till I tried this oil out on my softail ,I can feel and hear the difference,,smoother shifting and the engine is quiter The engine is quiet but the pipes are still loud as heck but thats the point RIGHT !!!

Very good oil. The motor feels like it runs better. I will keep using this oil

This oil did what they said it would. It's hard to find a product that really works like they say it should. I will keep buying this over an over again .I definitely will recommend this to everyone!!

Great stuff

I believe this oil is everything they say it is, my 114 m8 runs great on it quieter and smoother. Will be using the primary and trans. Oil also It gives me piece of mind knowing I'm running a superior oil in my Harley!

Good, solid, stable oil for my bike. I wish there was a "three hole" kit for when a man wants to change crankcase, primary, and transmission oils. Click one button and checkout. But I guess that's really more of a complaint about the website.

When one isn’t enough. Go big or go home

My 04 Harley Davidson FXDI Superglide runs great with your oil.I can hear and feel the difference. I will definitely continue using Amsoil products.

Since using you oil on my 103 I noticed when the bike got hot it still had oil pressure . I used Harley synthetic oil from purchase oil my 2013 when it got hot I had 0 oil pressure obviously your product is better

I use this oil in all three Harleys and works great, bikes run cooler and shift smoother. Very happy with this oil.
