My Ride: 2004 330xi
After five months, my trip computer reads 19.5 mpg. (93 octane)

Mostly city driving, with once every other week 100 mile highway tips. In the city, I use the go-pedal in a way that is less than economical.

I noticed a drop from 20 mpg to 19.5 mpg almost immediately after changing the oil to M1 0-40. Not sure what oil was in the car before, but it must have been thinner.
