Not something I usually concern myself with in this hobby doing local cruise nights and short drives but we're taking our first long (about 2500mi) round trip this year. I've swapped the 3:55's for 2:94's, It'll get fresh oil and filter, fresh set of plugs and check tire pressures before leaving. The few day trips I've done so far are giviving me 14mpg cruising close to 60mph in my 340/6 a-body. Can anybody give me approximate numbers that they're getting, if you keep track of such things. Please include body type, drivetrain and rear gears so we have a fighting chance at keeping this all straight😁! Also any suggestions on squeezing better mileage out of a six pack would be much appreciated.
