| Re: Synthetic, or is it SIN-thetic
FWIW Crane Cams position is:....For rollers no need to worry any good oil OK (and for this reason in my latest build I went w/a hydraulic roller)......for flat tappets along with the "proper ammt of assy lube(not too much/not too little" use Rotella for break in ONLY....then switch to any good oil....Their position is that once a flat tappet is broken in and able to generate rotation regular lube is sufficient and better for a gas engine than constant use of Rotella....Any oil industry chemists out there that can confirm this???
