If you changed your oil every 5k with Mobil1 AFE 0w-30 & a Napa gold like myself, I spend $28-$30 per change, that's at least $84 a year more or less.

One change of Amsoil SSO 0w-30, even if I have to buy a 5th Q in case I burn oil off, amounts to $68.50 before shipping. $10.50/Q and $16 for the filter.

So, if you go just 15k with that oil, rated for 17.5k in severe or as much as 35k normal, you will still be saving money compared to the $84.

From the Amsoil guy:
GM uses a monitoring system that monitors the breakdown of the oil, not just the milage with a dummy light
He's wrong, it's neither of those. GM's system monitors engine data that is already normally collected, and uses that to infer oil breakdown. It is quite effective without needing additional oil sensors but can't account for contamination. It doesn't directly monitor breakdown of the oil. I've found it to be good enough.

Chrysler uses a system with an actualy oil quality sensor, or did and I assume that they still do.

"EP" in my book. If we're talking strictly Mobil1, yes, I wish Mobil1 would have an "EP" 0w-30. My friend would probably buy the 5w-20 "EP" if they sold it in 5Q jugs more like the 5w-30. Forcing to go individual quarts isn't bad, just misses on a potential overall value savings. He runs 0w-20 in his Fit.

It simply be a question production facilities, shelf space, and potential market. I've tried the 0w-20 in the Prius, but it wasn't worth the cost buying single quarts, and demand likely wasn't high enough to offer the the bulk jug. It also may simply be their EP additives push a 0w-30 oil out of the 0 range.

A couple weeks ago I looked up Warren's 5w-30 trying to get a bead on what Wal-mart's stuff is. It is close, maybe a little thinner, to 0w-30 Mobil is viscosity.

Being that his post is from '06 I wonder how that impacts his discussion? Has GM since changed or always been that way?

In at least 2002-2008 GM definitely used the system I described. If it has changed, it would be in the last year or two.
