My bone stock (engine wise) 2004 330xi 6-speed averages almost 26mpg. I drive 70 miles a day going down a mountain pass in the morning and up in the evening. On flat, open road I get closer to 30mpg. I try to drive my 1997 Miata 1.8 5-speed as much as I can for work though 'cause I only have about 44,000 miles on my 330 and don't wanna rack up a buncha miles but it's been a little snowy lately and the Miata is basically worthless in the snow. Oddly, the Miata only averages about 30mpg.
