2006 Harley road king Police bike.
Out : whatever the last owner used.
I decided to try something different than what I usually use. And used 4 qts of Castrol 20/50 full synthetic oil that stated it was for use in Harleys.
The oil filter was a new Harley filter I've had since I wrecked my other Road king.,,

Nice shifting throughout the life of this blend (it did diminish in quality, still though.) Its very hard to tell the color-condition of the sump oil on this bike through the sight glass. Color seemed pretty dark, so I changed it--It had been a while since the last change.
I still feel a premature oil change was a good idea...not being sure how much it had been test ridden (short jaunts & not getting up to operating temp), when the prior oil change was actually done, etc;Good deal on getting the S40 with low miles! Are you saying you changed the oil because you clunked some shifts? I would not let that influence doing an oil change moving forward, not an issue. Less than 600 miles on the oil isn't even letting the oil break in, ha ha.
