RE: Tired of diff oils...
Man, I would go the other way if I was u...that oil must be going somewhere....I am running 10-10-1 on Alex's advice, and I must say I love the handling, though I'm not experienced in many different weights, but with this setup, I find it pulls nicely thru the corners, and can be induced to slide (very predictably) with a bit of throttle. Does push hard under braking though, but hey, it's better technique to brake toward the corner, coast around and accelerate out anyway...
