Amsoil is the only oils I will use for my Harley Davidson. Priced right and perfect for primary cases - quieter and smoother, the proof is in the product. Highly recommended!!!
I have used Amsoil's primary fluid in my Harley's for over 10 years and have never had anything but great results. I always have smoother clutch feel and great compensator durability with this product. I have used this fluid in three different bikes all with the same results.
Didnt realize the sound coming out of the primary with worn fluid….. much quieter operation now
Bottom Line
Yes, I would recommend this to a friend.

I’ve used this a few times and it seems like it works well. Fairly confusing figuring out if this is any better than the 20W-50 V-Twin oil for my HD. I think I’m going to try that in all 3 holes.
Bottom Line
No, I would not recommend this to a friend.
