my bike ran hotter with the Lucas 15/40, by like 15-25º on average... not a big deal until you get up over 225º but when the Amsoil and Rotella keep my bike between 190-215, it's a noticeable difference

Now that you mention it..those hot July runs in WI probably contributed to my stock coil frapping out (ambient heat plus the hotter mill temp musta baked the one that went buggers when I got home). I gotta get me one of them thar oil temp guages for sure! I'm still about 500mi from the next oil change & will be sending a sample in for analysis.
