Well I have to say that my friend's opinion that synthetic oil's uniform molecule makeup being more prone to cause leaks did give me pause. Only because of all of the instances I've read here over the years of new owners changing their oil and dealing with slight leaking from the oil filter cover gasket in their CBR's. While most of the time simply torquing down the oil filter cover bolts a little more is enough to solve the problem, we're all well aware by now how brittle those bolts are and how easily they can fail from over-tightening. So even if I didn't fully believe that my friend's warnings were fully valid, it's difficult not to weigh the "worst case scenario" possibility of a broken oil filter cover bolt against the advantages of running synthetic oil in the bike.
At this point in the ownership of my 2011 CRB, I've completed numerous oil changes without incident or the slightest hint of oil leakage after changing the oil filter cover gasket. I'm well versed in how much "hand tightening" of those bolts is required to do the job without "over doing" things and ending up with a disaster, so I guess my last lame excuse for not running Rotella in this bike has finally bit the dust.
