What would be the point? We're still on the internet.

Seriously, don't let the oil topic bury you. Some grades may be slightly better than others for a 4.2/4.0, but as long as you are in the ballpark there aren't any really bad choices. And living in CA, even in the high desert where you are, it isn't cold enough to worry about oil choices.

I didn't read your link above from BITOG, but anyone saying 10W oil is too thick to start a cold gas engine is just silly.

You can get Rotella 15W/40 in gallon jugs for a decent price over at the Pilot truck stop near you.

I've been running 10-30 all along, but his points about thick oil makes sense to me. So that's why I was curious.

The article on Wikipedia on multi-viz oils is really good. Does a good job of explaining how they make oil flow freely in cold temps. It's been my experience that few average persons understand what the xxW/yy really means.

I'll read it. The website I posted explains the xxW-yy. I got it the best I could for how long it was. Ha

This is very true. BITOG while certainty a wealth of information sometimes misses the mark.

I figure that as long as you stick to the OEM spec lubricant it is pretty hard to go wrong. The OEM`s know a little bit more then some internet author suddenly claiming we have been doing it all wrong for the past century.

Having been in the industry long enough to understand and experience OEM durability testing and familiar enough with lubricating oils to understand how they are graded, formulated and refined I`ll run my choice which might not be yours.
