Customer Ratings & Reviews

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.

We get our clutches hot. Other primary oils stink. Some smell downright bad. AMSOIL Primary Fluid smells sweet, even when hot.

Love this stuff!

This is the best I have ever used

This is a great product for HD Motorcycles

Great stuff. Have used synthetics in my Harley for 20 years with positive results.

Using it in all 3 places.

When changing the fluid at 5,000 miles oil still has clarity not as dirty as factory oil. Neutral is easier to find and shifts are smoother.

All the research I did recommended this fluid over the rest.

Keeps everything moving smoothly for those time when you want to dump the clutch and roll out.
