Without boring anyone with the details of "why", I've had some Honda Dino 10W-40 in my '08 CBR1000RR since I got it several weeks ago(And yes, I've already done one oil change at about 80 miles and am now up to about 160 and ready for the second oil change to a lower viscosity).
Anyway, I've ridden a couple days/mornings where the temps have been in the low to mid 40's and my manual calls for 10W-30 in that temp range(it shows the transition to the 40 weight at around 50-60 degrees).
My question is, is starting up with that oil under those conditions really going to hurt the engine? I always thoroughly warm the engine up before riding and go easy until the engine is fully up to operating temps. I'm going to go grab some 10W-30 ASAP but had the 40 weight to use and couldn't resist riding...now I feel a bit guilty...any opinions?
