I've been reading several threads about oil choices, and I've gotten lost in the distinction between Sportsters and the big bikes. In most of the oil threads I've looked at it's not clear who's talking about which oil for which bikes. Most threads seen to assume separate primary and transmission.

I went to the local dealer today and the parts guy told me that the oil tank on the right side of the Sportster is for engine and transmission and the primary case takes oil for the primary only. I thought I must have gotten confused until I got home, checked my manual, and verified that he was wrong, primary and transmission are together. <sigh>

Anyway, he recommended Redline V-Twin Primary Case Oil for the primary.

My question is, should I go back and replace the V-Twin Primary Case Oil with something else, or is that OK for '96 Sporsters primary/transmission?

 

That should be fine for your primary,what did he tell you for engine oil.

 

I think he suggested the HD brand of engine oil, but I bought Redline 20W50 Motorcycle Oil.

 

Your good to go
