Actually, I was thinking of it more as a potential choice for those antsy folks with older cars, like muscle cars, who have been stressing out over the decline in ZDDP in MS oils and the affect this might have on the life of their high performance solid lifter valve trains. The WPP logo made me think this might be a viable oil option if indeed the WPP stands for Warren Performance which is reputed to make a reasonable quality oil for WW.
Certainly, the HD oils, like Rotella, would seem a logical substitute, too.
Thanks for the feedback.
