In response to ""For what it's worth might mention I've been using 5W-30
Havoline regular
oil form "K-Mark", and the engine seems to like it. ""
Not sure that it might be what the pistons or bearings want to see under
load, I would definately like to hear what any oil experts out there might
have to say, the thinner viscosity may be good for less windage and possibly
a bit less drag all the way around, but, most of us need the protection from
higher viscosity, in my opinion, Dahlgren, others what input can you
provide?? Joe :)
