Let the great oil debate begin.

Let the great oil debate begin.
I searched a little for previous topics as I know this has been asked before, but I could only find an older post about this, and I want the communities take.
Going into my 1,000 mile service I was initially told synthetic is the oil to go with. Price isn't an issue, but a second opinion from another dealer suggested conventional for new bikes at 1,000. Then switch to synthetic at 4k. The fellow at the other shop I spoke with discussed the problem with synthetic on a new bike is the break in period and it runs a bit thinner and the new bikes he's seen have responded better with conventional only initially then reiterating the switch at 4k.

Thanks for any input.

You could probably just flip a coin for all the difference it would make. I went with the Dealer and stayed on Dino till 4K rationalizing that I didn't want to maybe nudge a warranty issue into play before the break in period was behind me at least. Otherwise, I really don't think that in a new motor dino vs synthetic makes a lick of difference as long as you don't exceed scheduled change intervals. In the long run though, I'm a synthetics fan.

Damn, I hope your 10th post is better than this crap again. There are no less than 50 posts with hundreds of responses for you to review until you **** synthetic.....or dino.
Here's 500 or so to start

Helpful ... Come on now ... This is THEE most discussed topic on this Forum ... There are pages and pages of "how to " ... "what to" ... "when to" ... "synthetic" ... Not trying to be a hard nose just addressing your ... "I searched a little for previous topics as I know this has been asked before"

When I have had the cases open either by splitting, opening a cam case, or having the jugs off, then I run W40 non detergent about 10 miles, drain,then fill, in Winter 20-50 synthetic and Summer W50 synthetic with a slug of STP both seasons. Obviously on a new bike the cases have recently been open...
Since OP is at 1000 miles, in warranty period and all that, he's stuck with whatever the dealer does. Never mind what he says he's done... Though he'll probably do something fairly good....
The idea that, say, W50 synthetic is a lower viscosity than W50 non synthetic troubles me. At http://www.astm.org/SNEWS/JUNE_2004/lanhen_jun04.html there's a short technical article... No mention for some special way of measuring synthetic differently from petroleum derived lube oils that I can see. If I had an SAE handbook...but mine's lost (and they're 'spensive set of volumes)...if I had I'd look up viscosity measurement procedures to make sure, but I'm pretty sure now.
I call, if not bs, then material doubt about accuracy of reality behind this quote: "The fellow at the other shop I spoke with discussed the problem with synthetic on a new bike is the break in period and it runs a bit thinner and t..." I say the guy's mistaken.
My experience has been that HD motors live happier lives with W50, if the weather is 60 degrees or higher (memory on that number?).
Clean first quality and in specification...but the stp bit is for open-ness only - HD does not speak to STP - it's just my own druther - and I'd skip it in a new bike.
