Looks like its down a little to barely 1200 ppm in the CK-4 Diesel. Probably still fine with the stock 340 cam but thought you'ld would like to know the formula was changed.

No moly either. Although to be fair Brad Penn shows little moly in the UOAs I've had done.

and the newest 'multi-vehicle' T6 Zinc is lower than I'd like even with a stock, non-performance cam.
