Smaller wear scar is better, meaning that on a test rig, the fuel with greater lubricity will result in a smaller scarring on the test surface.
Yeah, this is kind of what I was figuring without knowing the details. I wish there were any definitive testing of the effects of additives (I.e. diesel Kleen) on the wear scar indicators.
