With the disappearance of GC 0w-30, I'm looking for a replacement. My '01 GMC Sieara has a built 6.0 making about 500 crank HP. I only drive it about 2,000-4,000/year and change oil once/year. What would you recommend?

Castrol as it contains titanium. Titanium is reportedly one of the better anti-wear additives when the oil is cold. I'd use Castrol Edge 0W40.

Those GM truck engines seem to do real well on 40 weights judging by the UOA reports. The ones prior to 2007 that is when they didn't have AFM.

I'd look into either a 0W-40 or most any 5W-40 full synthetic of your choice.

The engine only has 28K on it, but it does use some oil, as do most LS engines. None the less, I'd like to minimize it. BTW, I'm not opposed to recommendations for most any brand of quality synthetic oil. I would like to be able to source it locally though, thus the leaning to Castrol or Mobil 1.

Did I read correctly that the Catrol Edge 0w-40 is a Group IV POA?

It has enough POA to be classified as synthetic in Germany, whatever thatís worth.

Would something like a 10W-40 EP help reduce consumption, or should I just not worry about it?

Castrol Edge 0W40, and yes it contains PAO when I asked Castrol that question.

But a 40 grade HDEO like Delo or Delvac would also work well.

LOL, yeah, but that oil in that category is IMO that much better.
As for HDDO they are OK, but they usually have high NOACK, they are formulated for different application.
If you asked question which oil is best for modern diesels, I would say Mobil1 5W30 ESP. That is why I use both of those oils in my cars.
