I'm currently getting around 23 to 29 mpg

. I drive city/hwy but I commute from the sub urbs to the city a lot and commute to work. But the roads here have higher speed limits like 70 or 80km an hour so that practically consitutes highway driving. Plus I do most of my driving out of the trafic jams though I want to shoot myself within them. Usually within one tank of gas I get around 550 to 575 km. I have a high mileage engine too 250,000km without doing any rebuiilding on the UIM/LIM, just regular maintence.
Btw Goonz, nice post to reach 9700 posts :P
