I have been sticking with honda oil since I got my bike. I have been changing it every 3,333km. Recently I used some quaker-state rather than the honda stuff.
My VFR normaly runs at 80*c. In the cold (like sub-zero) it would occasionaly dip below this while on the highways. Now that I have the quaker state oil it seems to sit at 75*c regardless of the external temperature.
This seems to be a good thing doesn't it?
What in the oil would make that much of a difference?
If the oil change is responsable for the 5* shift the I am suprised. I never imagined that friction-type heat was responsable for so much.
(VFRs at idle sit at 100*+ so all my numbers are for highway riding)
