Dragsix, if you contact DA Lubricants, I bet you can get a spec sheet like the one I posted for the CCCA motor oil and compare the two side by side.

Cmayna, same thing. Get the specs for the Valvoline racing oil and compare. Does it say on the l;abel how much zddp is in it?


Speedway Motors has a chart with lots of different oils listed.

Valvoline VR1 has 1300ppm zddp

Shell Rotella T series oils 1450ppm
PennGrade 1 is listed as containing 1500ppm, so according to this chart it isn't the same formulation as Classic Car Motor Oil.

Mobil 1 Racing oil is 1850 ppm
