I just changed from sin3 to Mobil 1 in engine and primary, Redline in trans. Engine gained about 5/10 psi on oil press, clutch releases a lot better and the trans is quiet for a change. IMO Dan

I am having Syn3 put in my bike now at the 1k service (free upgrade), so i will see how it does with that.
I am done with Syn3. Last year I had heat and noise issues with it. I also consumed too much oil between changes. Went to Mobile 1 and solved everything, although I probably could have used Royal Purple or any other real synthetic.
If you become a Preferred Customer($10), 20W-50 runs $6.55 per quart, if you buy a case of 12. $6.90 for a single bottle. It might be a little more than the other brands, but it's going into something pretty special. Plus it's a once-a-year/25,000 mile oil change. It's also works great in the primary, trans, and engine.
