My G/Fs 2002 Monte Carlo SS (3.8 L motor) is beating me with 26 mpg average. Its no doubt the driver. I tend to be a lead foot.
Welcome. Be suspicious of the Monte Carlo mileage if it comes from the onboard display . I like the 3.8 motor and currently own three of them but the mileage computer in my 2001 Impala is programmed to ready about 14% better than reality.
