I would hesitate to use Cam2 unless it was cs., and for a beater.
They primarily sell to the private-label or "house brand" class of trade. I've seen the wholesale prices for the bulk Cam2 that goes into quickie-lubes, and it is *cheap*.
Paul back then cam2 was made buy SUN for PENSKE racing. SUN and PENSKE went separate ways and SUN sold the CAM2 name. THE product is low price and LOW QUALITY .
I was hoping that it had all the performance characteristics of something more modern, like SL, but the zddp of SF. Oh well (tongue in cheek), there's always GM EOS with its 6000 ppm zddp.
