Some say the switch to 5W-20 from 5W-30 has more to do with a marginal increase in fuel economy to satisfy CAFE standards. I know Dodge and Chrysler started using 5W-20 over the last few years in the Stratus and Sebrings with the 2.7L V-6 engines, whereas previously that motor used 5W-30, like in the 2001 Intrepid I used to own.

From everything I've read up on, the MPG difference between 5W-20 over 30 is very marginal. One thing I did see though was at BITOG, and seemed to indicate 5W-20's look like they have a higher content of moly in their mixes over a 5W-30, so perhaps to make up for the thinner weight the additives were beefed up a little bit.
Yep - not much difference. Use whatever is on the oil cap and/or owners manual.
