Customer Ratings & Reviews

I have HD FXST & Buell X1 started running your 20/50 synthetic V-twin motorcycle oil this season.. Right way you could tell the bikes were happy! Out on the road they are running about ten degrees cooler then with conventional.. Plus being on the preferred customer program I had my order within four days which was awesome!

Use it on my Harley Davidson Touring Bike The engine seems to run smoother and quitter.

Best v-twin oil i have ever used

Best oil on the market

Love it. Keeps engine running way cooler and quieter

I use this in all 7 of my bikes.

First time using this oil dropped my bikes oil temp 10° Highly recommended.

Goes in my Twin Cam 96 Harley. I've been putting it in all three holes. Works well.

Great for my motorcycle

I have been using Amsoil 20/50 synthetic engine oil in all my bikes since 2003 and I prefer to use no other product than this. This oil Meets all my driving needs during the winter and the hot summers I have never found this out to fail. I am 100% satisfied and will continue using Amsoil 20/50 synthetic. Also whenever I order from Amsoil my order comes within a few days.

I use this in my Harley and it seems to do a good job.

Great product have used this product for 10years. Will continue to do so.

Amsoll is the life blood of my Harley. Air & Oil are the 2 cooling agents that keep a Harley running. AMSoil does it better, the bike runs quieter, and I have confidence that my girl will keep on going even in these HOT Florida days.

This is the best oil I have found around. The price is comparable to other brands but they don't do the same job. My engine runs cooler and for a Harley that is air cooled that's important and for my bike being 27 years old it needs the best.
