Thanks for helping ease my worries, guys. I'm glad that I made the switch to M1 0w-40 SS now; I was contemplating waiting a bit longer, but now I'm glad I switched.
So, is it common for most dino 5w-30's to break down that quickly? It would be nice to know as 'ammo' for the folks who run 5000+...
Just got my analysis back...I'm a little worried about a few of the readings, any feedback is greatly appreciated.

Jay- you're correct; the last oil analysis I had done on the Tahoe was in February of 2002. We had just hit 10K miles, and I sent my first M1 sample to the lab for analysis (had sent the dino in previously).
For note, our winter temps hit the mid teens, sometimes lower. Our vehicles are garaged...
First of all, I'd like to say that this board is truly a blessing! I've been religiously reading it for the past few weeks, and the information contained within is nothing short of incredible. Talk about a great community, and tons of information...I can only hope that eventually, I'll be able...
