Just recently bought my crown vic and couldn't help but notice my 4.6 is sucking down gas. It may be because I just installed my flowmaster mufflers and I'm pushing it to 3-3500 rpm off the light and getting on the gas in traffic. I plan on getting a k&n cold air intake soon. What else could I use to improve fuel economy besides going 40 mph at 1100 rpm. Thanks guys! |

Go to www.crownvic.net to checkout some of the threads there. The CV, GM, and TC are not know for their fuel mileage, but there are a few things that can be done to do minor improvements. The common ideas of a better intake and exhaust system does help some. Having a custom tune done to the PCM will help increase power and help a little with the fuel mileage.

It could be your driving style.If you are punching it "off the line" you are using more fuel than you would if you just accelerated slowly. Also, if you are hot rodding it to hear the exhaust sound you are going to get lousy mileage.
My 03 P71 averages 18-21 on the highway and 17-19 if I have to get to the fire station for a call, idle for awhile, or city driving. |
