This is a lubricant right? Description its not.

All primary chaincase oil is PRIMARILY used to cool the clutch. It is also a lubricant for the chain etc. But it's primary function is to cool the clutch. That is what the statement in the add is referencing. Yes, it lubricates the primary chain and more. This is all I use in 5 Harleys, love this stuff. I use all Lucas specific oils in all 3 Harley holes.

Can i use this in my primary on my 2014 dyna

Yes, any year primary. Better clutch action and less gear clunk. I run it in my 2018 Lowrider.

So i can. in primary of my 2013 road king?

if you have a 3-hole bike yes, engine oil hole, primary oil hole, and transmission oil hole
