Synthetic Oil change
Got a question about Synthetic Oils. I have about 7k on my motor (stock). I am considering switching to Synthetic from Dyno oil. Should I break my motor in a bit more before the switch? And is there a problem with leaving a small amount of dyno oil (whatever will not drain out during the change) and adding Synthetic? Thanks in advance.

RE: Synthetic Oil change
you can switch to Synths once the rings have had a chance to seat, and to tell you the truth, with the materials they are using today I don't even know if seating the rings or breaking in an engine is even an issue.

some Harleys come from the factory with synthetic. Lots of autos come with synthetic from the factory. I think you're ok.[/align]

Old habits are hard to break I guess. My last Harley lasted 17 years (still running strong) useing HD 20-50.

RE: Synthetic Oil change
Just put it in and go...the whole break in thing is such a load of crap. Your engine was broken in within the first 50 miles. Also don't use HD's over priced Syn3...it's crap too.
Mobile 1 20/50 for the engine and primary and Mobile 1 75/140 in the transmission...you'll be happy trust me on this one.

I just changed from syn3 to Mobil 1 20w50 full syn. 10000 miles on an 06 Ultra. Gained about 8/10 psi on oil pressure. was 24/26 now34/36. Bike has had low pressure since new. Use Mobil 1 in primary also and Redline Shockproof in transmission,
