16 around town stop and go..low 20's highway If very light foot touch maybe 25 steady state .4.7 small V8 286 CID not to bad on fuel. If your not hitting these numbers scan it for codes or read live data fuel trims STFT and LTFT short and long term trims.

YOU DON'T KNOW HOW TO DRIVE. WATCH THE 'PERFORMANCE/ECONOMY' GAUGE ON YOUR SETTINGS. IF YOU DON'T GET 95-100% AROUND TOWN, IT'S YOUR DRIVING. KEEP YOUR FOOT OFF THE BRAKE. WATCH AHEAD AND TAKE YOUR FOOT OFF THE GAS AND DONT PRESS BRAKE TIL NECESSARY. DO NOT ACCELERATE QUICKLY. WHEN YOU ARE DRIVING BEYOND STOP AND GO GET THE CAR INTO HIGHEST GEAR AS SOON AS POSSIBLE BUT GRADUALLY/MODESTLY.. YOU WILL NOT ONLY SAVE GAS BUT TIRES, BRAKES, AND SUSPENSION.
