Here is the latest info I have (2018) as well as the older stuff (Synthetic and dyno-juice). Note that Valvoline now has a Pro-V Racing product line, these are absolutely the max amount of zin/phosphorous, etc...will they live on the street??? No idea...they specifically say racing application only!

However, what about the 'Valvolineā„¢ Pro-V Racingā„¢ Break-In Oil' combo? Even for a guy like me who's moving on to a hydraulic roller setup it seems to make sense for break-in duty...no?
