Have about 6k miles on my current oil change but with all my credits I’m sitting on about $400 at FCPEuro (been running Molygen in my Grenadier and using it in my Yamaha SHO outboard). Any real issues with me running something like that in an older machine? Is soot contaminant that much an issue? I did tune it and run about 60-80hp more. Currently it’s on Amsoil but UOA of Molygen has always looked pretty stout.
