it doesnt make a difference, i would just stick with the 10-40 motor oil, dont bother buying the honda stuff, just dyed a different color and 3 or 4 bucks more a quart, get some decent 10-40 oil and be done with it...have fun!

Uhh

Why use 10-40?
Who buys Honda Oil anyways unless you have a motor that requires 0-20?
