I emailed Shell a while ago about Rottela. I got an email back and also phoned and talked to one of the Reps. They said Rottela has now 1200 ppm and recommended the Racing Oil that had 1500+ PPM. They recommended Pennzoil Racing Oil mainly because Shells owns them. I have heard Val.Racing Oil is Good and also Royal Purple. I have been using Val. Racing Oil 40 weight for years and now am almost out of it so I need to buy some more oil for use in the solid lifter cam motor.
