anyone switch from auto/motorcycle oil to diesel oil in your bike? If so, what are your thoughts? Improvement or not?

 

Improvement in what way? What would you be expecting?

 

I kinda chuckled when I read that in the owners manual of my new ultra....

 

Yeah, it's been an authorized "back up" option for decades,

 

quieter than engine than using synthetic. Currently using M1V-Twin. Noisy at highway speeds.

 

Ran Rotala-T in my last bike with no issues... there is plenty of info available regarding its use on the web ( the Vulcan crowd has been running it forever)

I'm sticking with H-D oil in my new SG.... at least for the time being

 

Mine's noisy too on M-1, but I still run it. I'm sure the diesel would be quieter, ( what wouldn't be?) but I wouldn't trust it's benefits long term. M-1's rated now something like SJ ( or L?)

 

No, but I hear sewin machine oil is DA BOMB!

 

I run it in the dirt bikes, not in the Harley's...yet.

 

Rot is not diesel oil only.It is one I like for quality and cost
