So basically we need higher zddp (zinc) additives to keep everything from wearing and to reduce friction, but then this causes foaming issues, which I imagine doesn't do well for lubricating much of anything. On top of all that we have to worry about ash content to keep carbon buildup down, AND make sure the oil still lubricates under fuel dilution because we all know that's an issue we have too. Then we also have synthetic vs dino, cost vs frequency, carbon vs bearing wear, on and on and on, and who knows what changes everyone has made to the oils. What the F?? So much thought going into oil.
