Synthetic benefits in differentials ans transmissions
When I lived in a climate that got genuinely cold in the winter, synthetic was a big benefit in differentials, transfer cases, and manual transmissions. These units didn't really warm up in cold temps, so mileage really did get better with synthetics.
Take a bottle of 90W gear oil and the synthetic version and put them in a 0 deg (F) freezer. Then take them out and slosh them around. The difference is (was, anyway) night and day.

Something else I noticed about trying to get good mileage. On my 75 mile freeway commute I have been putting the cc on 65 and kicking back, and listening to a book on CD. Friday there was a guy that pulled on the freeway with me and took off ahead of me. At about 50 miles there was a traffic jam and I caught up with that same guy. It appears that being in a hurry does not gain you much.
