Maybe just use a great oil with some Lube Control and call it a day?
I've used Pro-Blend for many years but after having a VOA done there doesn't seem to be any beneficial elements in it. I researched all the lead compounds that were mentioned and they seem to based on old technology from 30+ years ago. The Pb's only seemed to be effective at low rpm's and no one had any info as too their lifespan.
