Wellllllp, I have been researching the web for more current info on rotella. Doesn't look good. Looks like specs changed in 2013 for rotella and the zinc is supposedly removed to extremely low levels unless labeled "not for highway use". I haven't looked up the Morris oils yet but Valvoline has a 30W VR-1 oil with higher levels of zinc and limited additives. It's $34 on Amazon for 6 quarts. What do you guys think of all this?

Oh, and it supposedly doesn't foam like diesel oil.
I'll probably run rotella 30 for now until I hear from shell that this is the case. The flat tappet Classic car guys are still running rotella with no ill effects. Plus it's $14 at Walmart
