Looks like the Valvoline Race has the most Zinc at .20. Any info on Penzoil Race Oil?

I just visited the valvoline web site to figure out where to get their race oil. I found they have three types of race oil, conventional, eynthetic (both listed as "not street legal") and "VR" oil. ALL THREE list zinc at 0.12, not 0.20 as stated above.
