For those who made the switch from regular oil to synthetic, did you see a increase in gas mileage?

Neither did I. It's a myth that synthetic oil is substantially more slippery than regular oil. Synthetic is superior in numerous ways but providing better mpg is not one of them. I use synthetic in both vehicles and all the bikes.
Ditto. I use synthetic because I think it's better for the mechanics. It doesn't seem to have helped any with MPG. But it does seem to run a bit quieter.
