I'm already 6000 miles in to using Redline 5W30 with a RP 10-48 filter. Things have gotten a little better, but there is still cold start chatter and a warm tick.
Ill be honest. If i STILL had issues with redline..........i would first try a new filter. And if that did nothing, i hate to say it but i would seriously go straight to PYB and try additives.
I know we are not fond of additives much but you just tried the top of the line base stock with a boat load of moly and it still is not right. There is not much room for improvement (that we can find yet) so i would start experimenting.
Liqui moly makes 2 in particular that I’m interested in. The ceramic one and the lifter additive.
