Harley Primary
By
MICHAEL A.,

The main reason I recommend the Amsoil primary fluid is because it eliminated my clutch chatter. Clutch would start to chatter using screaming eagle oil after about 2500 miles, after changing to Amsoil I no longer have any chatter. Good beyond 5000 miles.
Bottom Line
Yes, I would recommend this to a friend.

Oil Change

Was time for an oil change, and have been using AmsOil products in my truck since 2016. I've tried other oil products in my truck and have not liked the results. Harley-Davidson does make a good product for their bikes, AmsOil just does a better job especially during warmer climates or heavy traffic when oil breaks down faster. I have never tried AmsOil Primary Fluid and thought I would give it a try.
Bottom Line
Yes, I would recommend this to a friend.

This is what I run in the primary of my 117 M8. I’d say it works great and I have absolutely no trouble finding neutral as some people say with these bikes.

Yes, I would recommend this to a friend.

Smooth clutch operation
By

I was using the 20/50 oil in the primary housing, and it worked very well indeed. However, upon switching to this dedicated formulation in my Harley, the clutch feel and operation is improved, smoother engagement than ever before. Chain case noise seems reduced a bit, but cannot say that for certain. AMSoil, in my opinion, offers the very best lubricants available for Harley Davidson motorcycles. I have never heard anyone unhappy with these products.
Bottom Line
Yes, I would recommend this to a friend.
