My indie guy and the dealership told me to not run synthetic oils in an EVO. I haven't. Can suck on a long road trip because an oil change may need to happen out on the road.

 

Been there and done that. I switched back to non synthetic and the problem went away.

Does harley make a non syn3 anymore for the tranny and primary? That is all I see.

 

Good question! I haven't looked recently, having ample stocks at present. If you have the time and patience there is a Tech Oils section where you can browse the zillion oils owners use, trying to avoid the scurrilous MoCo and its products!

 

I don't believe so.

Formula is synthetic

 

I'm not a proud person and enjoy learning new things, but I have never heard of Formula+ being a synthetic oil, nor can I find anything on the bottle or from Harley saying it is synthetic. Not saying you are wrong, I would just like to learn where you got that information.

I am sorry semi synthetic. And I was told that from the dealer. They told me that it is approved for evo' s.

 

formula+ is 50wt oil. Not synthetic at all. Here's an analysis done somewhere else. Redline makes a specific lil for evos non synthetic one for the primary and one for the gearbox.
