find someone who sells stuff called EnviroMax... u will get an extera 4mpg the 1st time and the mpg just keeps getting better... i have a 94 4dr gran sport with the same engine(3800) and i romp the accelerator all the time and i still get 21-22 mpg...which means i take off of the lights and stop signs like a mad man

that would be the correct gas mileage, i get about the same thing with my regal, its pretty good compared to other cars of the same size and engine these days

there are some quick ways to increase the mileage, but there not free, a cold air intake is a good way, there are also things like E3 sparkplugs that will increase the mileage and fitch makes a product called a fuel catalyst which will increase ur mileage by around 2 mpg and they last for 250,000 miles with a full waranty

a simple cheap way to increase fuel efficiency is changing the thermostat. heat soak causes a loss in power and fuel efficiency. its a simple cheap part to install and should get you and extra 1-2 mpg easy.

hah your lucky, on my 94 regal i replaced ignition wires spark plugs, o2 sensor, air filter, i bought something called the tornado which sits in the intake and "boosts" power and gas milage, and i still only get 18 mpg
