I had synthetic oil put in my 2012 Ultra Limited at the 1600 k service. The mechanic where I bought the bike suggested it when I purchased it. After talking to another dealership, they said I should be running the HD 360 for at least 5k. Of course that it always comes with a labour charge. Any recommendations as to what the standard protocol should be.

 

Changed to synthetic on both of my bikes at 1k service

 

To bad the factory didn't know what the dealer seems to know. They put syn in the 110's from the factory. As does Gm in Corvettes and others.

 

Lol, my car came from the factory with full synthetic and when I get home my bike will be getting full synthetic in all three holes for its first oil change

 

Changed to syn at 500 miles.

 

Sounds like the norm.

Cheers

 

Synthetic oil is thinner and cools faster but noisier because it's thinner. At least that's what I've read. Good and bad in my book.

 

Well they were right. Had the oil changed back to 20/50. What a difference. Sounded like a major bearing failure with synthetic.
