V-Twin Primary Fluid
By

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.

Been using this in my closed primary HDs for years and it’s great. You can feel the bike running smoother when you change the fluids. Some of the older models say you can use the same fluid in all 3 holes, but why do that when THIS exists??
Bottom Line
Yes, I would recommend this to a friend.

V-twin PRIMARY Fluid
By
MARK,

Disappointed. I love Amzoil and most of their products, but this one just hasn't seemed to keep up with current practices. Even Harley has come out with a new updated Heave Duty Primary Fluid, and the 80w-140 range. But Amzoil has not. They don't even list the viscosity on this old oil. Time to get a new Heavy Duty Primary Oil out there, Amzoil. A lot of us v-twin customers are waiting for you to update and come out with something better than Harley.
Bottom Line
No, I would not recommend this to a friend.

Everything you’d expect. Only thing I’d change is the amount per bottle seems like a lot of bike primary takes quarter or so of a quart so kinda annoying having to buy 2 or underfill….
Bottom Line
Yes, I would recommend this to a friend.
