I still do not understand why everyone is acting as though increased fuel economy is unwanted.

Yes, it does.
It is why the catalytic converters got moved closer to the engines to get faster warmup.

when using the syn oil, on average, how many miles should you run before changing?
A month ago I put in RL 0w-20 in my wife's '03 EX. We'll change it out next year and in the meantime I have no qualms about running it during SoCal summers.

In fact I'm running Synpower 0w-20 in my Honda for the summer. I admit it's mostly for the novelty of using a non-Mobil 0w-20. I have a jug of Ultra 5w-20 that was supposed to go into the car, but the Synpower looked too tempting on the shelf at Wal-Mart.
If there's no difference, then why is Honda slowly moving their line-up from 5w-20 to 0w-20, starting with the 2010 CRV?
There IS a difference in fuel economy between 5w-20 and 0w-20, but the difference is minimal. However, when millions of cars on the road make the switch, it can potentially result in a notable reduction in gasoline consumption.
My point is that there is no significant performance difference between a 0w-20 and a 5w-20 in the summer heat. If you want to see the 0w-20 shine, try the comparison while short tripping in winter.

Maybe, maybe not. Look at the two Redline products -- the 5w-20 has an HTHS vis of 3.3 and the 0w-20 is at 2.7. I would conclude, therefore, that if one has an application in which HTHS is critical (some might say that's ALL applications; FWIW I would not), there will be a difference.

Absolutely, the required HTHS is largely determined by how hot the engine runs and how well the cooling system works.
My sludge monster '97 Camry V6 engine ran hot, so I chose to use Red Line 5W-30 with a high HTHS of 3.8 and a high flash point.
However, my '09 Civic Hybrid runs cool and safe with RLI 0W-20 and a HTHS of 2.9. I've tried to overheat this tiny 1.3 liter engine, and it can't be safely done on a public highway (meaning I've redlined the engine for miles on a 100°F summer day). No oil temp gauge, but the coolant never crossed 201°F. After this run, the auto stop still activated, indicating a cool engine.

I know people typically prefer Synpower these days, but is it really going to be that much better over M1 0W-20? The current deal at Autozone is really tough to pass up.
