Ok- so this is a blatant ad for us now distributing this fine oil.
But it is the stuff to use on our early cars. Brad Penn 20-50 has all the ZDDP additives needed by our "valve adjust" cars so cams and rockers don't wear prematurely. The new standards established/ followed by Castrol GTX, Valvoline, Kendall GT-1 ,and other dino oils no longer have the level of additives required in them



This green oil meets or exceeds API SJ/ CF service categories for heavy load protection

We have it by the case at $4.75 / quart or $61.71 case of 12 inc Ca sales tax.
