I kind of know what I'm getting myself into here, but it's a fairly simple question...
What are you all running for oil on your Harley's? Engine, trans & primary?
Naturally the manual highly recommends Screaming Eagle SYN3 or Harley Davidson 360. But here's the thing that caught my eye: it says if those aren't available, use the weight of your choice but to *make sure designations for diesel engines*. A friend has been running it in his modded 96 Twin Cam for the past year and loves it. His bike also calls for diesel engine designation if not running the aforementioned lubes.
I've also been told by a number of people that a lot of people just run that same oil in the transmission and primary as well.
I'm looking into Klotz because I run that in my sled and I love the shit, and I have a local source. In reading what little is available on their site, it states it "meets and exceeds warranty requirements for compliance and protection" for the M8 engine, but I can't find any classification that says it's for diesel engines. And for shits & giggles, I'll be ordering their transmission & primary specific lubes. I like their protection promise, but how far will that fly if something goes horribly wrong after running it for 5000 miles?
I don't need any more tips or instructions on HOW to change any of those fluids. Just picking to see what everyone's running. I'll take the different engine models into account as well. I'm also curious as to what your manual calls for.
