Customer Ratings & Reviews

clutch action is better

Awesome product that I use on my Harley Davidson Limited

Bike shifts noticeably smoother and finding neutral is considerably easier. Yes, my clutch is adjusted properly. This is just a superior product. Spend the extra money and your bike will thank you.

This Stuff Works Great Is The Primary, Love It ....

Great product

A kit would be great, include the seal and plug o-ring. I went to HD to get the seal and they include 3 o-rings. Now we have to store somewhere I’ll remember. Ha

Amsoil MC products are what sold me on Amsoil.

I own a Harley Davidson Road King Special and this primary fluid is the ONLY brand I trust to keep my shifts smooth and clutch clean

Great product

my transmission shifts the same regardless of what I run in the primary but different oils can have different effects on the feel of the clutch. this gives a solid feel without the clutch feeling harsh or grabby like a couple other oils do and I trust Amsoil to give me top wear protection.

Smother Shifts, Effortless to Find Neutral! This Stuff is Great, Seems to do a lot better than 20w50 of whatever brand. I will Buy Again!

Better than SYN3

It works great in your clutch to help it last longer

Great products

I like it works out

Amsoil always. I never use anything else. Great Product

Best product you can buy

I have only put AMSOL in my bikes. My Fatboy is at 25,000 miles now leaks. only Preventative Maintenance.

I just changed the primary oil after using Harley Davidson oil and I have to say the clutch engagement is super smooth now.

AMSOIL 20w50 v-twin engine oil is the greatest. I will use nothing but AMSOIL products in my vehicles. I’ve been using 20w50 v-twin oil in my Harley’s for over 13 years with confidence and no issues.
