Anybody have any idea of how much ZDDP is in a bottle of STP. I have not seen any used oil analysis or VOA with the popular STP additive to guess how much it would raise the zinc ppm levels. I did a search and could not find a single OA.
Could somebody doing a used oil analysis in the near future pretty please throw in a bottle (or even half). I promise it won't burn out your O2 sensor if you have it in there for the just the last 2000 miles.
