When refiners cut ZDDP (zinc) levels due to EPA regs to compensate they increased molybdenum (moly) levels. The added moly is what is bad for wet clutches.
DAMN!!! Another oil thread.Kinda feels like winter. That seems like when the tire/oil threads brew their ugly head
You see, this is why I use Royal Purple automotive synthetic, that way I don't have any of these issues.
+1 Shell Rotella T6 5W40.
Another +1. Love the stuff, smooth shifts, good for wide temp ranges (for those of us that ride in cooler weather as well as warmer), makes the bike feel sexier, etc.
OK....just wondering how the masses feel about this engine oil weight.
Not that i have used it, yet, but I found a very nice semi-synthetic high mileage blend at the local autozone. Hey Baby is 11 yrs in and has a little over 83k on her. I have screened the last 5 oil changes and have not found anything at all as far as shavings or debris.
Those oil changes cover almost the last 20k miles. I know Mama Kaw doesn't recommend it, any ideas on this considering the age ang state of my motor. Inquiring minds would like to know.
Stay cool this weekend, and ride safe.

I used oil once.
Call me silly, but I run whatever SAE certified dino 10-40 I can find...if the motor makes it 10yrs and 100K, I'll be happy with that and consider I've gotten my $$ out of it. (05 model)Dont use energy conserving. Your motor might make but your clutch will not.

(05 model)I won't call you silly. That's what I used for 90,000 miles and for the last 10,000 miles I used Rotella 15-w40. Had to replace a water pump a few thousand miles ago but engine is still great!!
