Yes I am running HP4S 10w30. Good read on those quotes. Thank you
You're welcome...
Honda specifies 30 over a 40 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...
Any one of 30 grade 100% synthetic motorcycle specific oils will meet
and exceed both your racing and mileage expectations...
Quote Gmtech94 about the riggers of endurance racing...
"When I raced we were sponsored by an oil company and helped with the
research of their product .The thought at the time was to run 20w50
race oil to provide for the best lubrication under racing conditions
hence no oil related failures . After many races and a lot of real
data research the conclusion was in this case to run a 10w30 oil as it
provided better lubrication and less engine wear over a long period of
time ,remember endurance racing in 24 and 30 hour races . Although we
never had an engine failure due to oil properties we did have a lot of
feedback on engine wear as well as transmission and clutch wear . I
have to say we did abuse these bikes on occasion with spinning the
back wheel to turn the bike as well as the occasional fall .The
ignition was a weak link but I could change out the pulsers in about
17 seconds once the bike was in the pits . In conclusion 10w30 ran
cooler and did not break down as much as the thicker oils did."
Aluminum most commonly presents as a wear metal in used oil analysis
results, but in some instances it could also be a contaminant or
additive. In this video Mr.LE looks at the possible sources of Aluminum in
your used oil analysis results to assist you with troubleshooting.
