I'm not using any yet? I'm on my third oil change, not counting the 1000 mile change, but I run synthetic and still change at 3k. I run her on nasty dusty gravel roads, so I like to keep it changed.
I'm running HD Dino until my next service at 5,000 miles. I have about 4,500 now Then going to Redline. I'm running Redline Shock Proof in trans. Our bikes run hot. I woul not worry about it!!!!
No oil measurable burning here...My 2000 has 82k miles on it. I never have to add oil between changes. The exhaust burns clean even if you look at in the dark with a flash light...The dino oil I've been using since new must be doing it's job.
all Harleys will use some oil...if they don't...sumptin wrong...some a little more than others...but all burn something...just like a car...it may take longer in a newer bike....but eventually it always drops. Mine uses maybe half a quart every 5000...it's an 05 88"...
