I agree...
My experience is that Honda can be trusted... if they recommend in
writing a 8K oil interval then it will meet and exceed your mileage
expectations because I believe after talking with the engineers at
Honda that they do thoroughly test the oil... in fact it doesn't
matter to your engines longevity if you run Dino or Synthetic... or
even 50 40 or 30 weight.... no one is wearing out their engine... but
it does matter in the amount of rear wheel HP is wasted in unnecessary
oil drag... between a 30wt and 40wt is 2 to 3 HP in unnecessary oil
drag... between a 30 and 50 is 4 to 6 HP in unnecessary oil drag...
choosing the freest flowing viscosity of 30 as prescribed by the
official Honda manual over a 40 50 is smarter because it will:
1)increase HP at the rear wheel
2)quicken the throttle response coming out of the corners...
3)decrease over all operating temps...
4)increase the oil flow at the critical bearings...
I admittedly popped in on the last page of this discussion, but I'm under the impression that the above weight oil is not good for wet clutch bike engines. "Energy conserving" circle = not for bikes I've always read.
Or should I be quiet and read the whole thread?
