Nice UOA. I used Red Line 5W40 for a few years with excellent results, like yours. Two years ago I switched to Mobil 5W50 (hard to find viscosity) and the UOA's improved slightly, so I am very happy with this choice too.
I am thinking about switching again to the new Joe Gibbs 5W40. from Jake and L&N Eng. Anyone try this yet?
