| i have a huge difference between the two: highway: 340 miles per tank (~23mpg), approx. 70 mph city: 220 miles per tank at best (under 15 mpg), shift at 3K 120 miles per tank less driving in the city?! i know the typical things to check for bad gas mileage: O2 sensors (new), pcv valves (old), vacuum leak, etc. however, my question is: what would account for great highway mileage but terrible city mileage? wouldn't one of the above mentioned issues affect both?
