You're right Slither. My commentary would indicate Mobil 1 does not have the highest. I. said it has
among the highest because I did not want to check all commercially available oils. You also will find very few providers of 0W-50 or 10W-60 viscosities which is every bit as important. Even more significant check the chart in the next post and you will find that Mobil 1 0W-50 does have a
zinc level in excess of 1300 ppm. In fact they represent it as exceeding 1800 PPM.
This search for the better lubricant is not about whose dog is bigger although it can feel that way. ZDDP is certainly one metric we want to pay attention to. Lubricatiing qualities at the elevated temperatures and pressures that racing engines (even old ones) are capable of producing is what the search for the best
oil is all about. If you like Brad Penn by all means you should use it in your engine. Looking at the
oil selection issue through a wider angle lens might cause others to choose differently.
