Good one Jeff :-)
Parked and with the engine off I assume... lol
ofcourse if it is not running, if it is running milage is worst, infinity consumption/per mile.
the e34 guzzlers we love
my e34 does 5.2km/lit (OBC and manual readout similar) roughly 19lit/100km on 93 octane. all stock and loves all the petrol she can take.

the ///M5 did about 16city/25highway. if i was really light footed i could get about 28-29 highway. But who drives an M5 with a light foot?

proper tire pressure ensures that you have the optimal part of the tire in contact with the road. underinflated tires provide a lot more surface area to come in contact with the road, thus increasing friction, and reducing MPG. If you just make sure you have your tires filled to what it says on the sidewall you should be getting optimal mileage. Make sure to check monthly though, and as temperatures change drastically!
can't help you all that much with the 'types of tires' vs 'mpg' question though. I have a few ideas, but i'm not sure if they're correct or not.

Just wondering though, since this is the first car I've ever owned that needed low profile tires...
I asked a few people, and they said 225/45/18 should run about 36psi.
But when I brought my car in for an Insp. II at BMW, they filled the front to about 41psi, and the rear 36psi... does this sound right? Should I stick with this setup running my tires? Or go with 36psi all around?
I think that its not all right ... i dont know the exact preassure for those tyres but the rear tyres must be allways at higher preassure then the front!

depends on the time if year for me. if its winter i'll go with lower psi all around for better traction in snow. However if i'm going to do some spirited driving, i'll fill up to about 41-42psi front and 38-40psi rear. Thats just my preferance though. I was running 245/65/17 (i think thats what i had on)
