Bad gasd mileage

[equeree]

hi, my 2.7 charger is getting only about 210 miles to the tank, what can i do to get it to a higher range? i already changed the air filter and ran a can of seafoam and even cleared the adaptive memory for the engine computer. what else can i do to help with the mileage? it only has 32k on it and i try to keep my rpms below 2k. whats the normal mileage to the tank am i supposed to be getting?

Damn! 2.7 magnum gets like 280-320 miles per tank. Mine has 45,009 miles and all I've done since I got it 15 months ago is got the oil changed.

Tire pressure? Check the sidewall and bump it up to the max and see what happens. It's worth 2-3mpg on my R/T. Ride is a little rougher, but not objectionable. Mobil 1 might help as well, but not much.

Welcome to the club,

I actually get any where from 18 - 19 mpg in the summer time and 14 - 16 in the winter time.

thank god i was getting scared because i was gettin 14 now thats it's winter so this is normal?

and just to let you know equeree you have a v6 not a 4 cylinder dont expect much

[pigpen]

Yup, in the winter months they use different types of gas,


Now also I have flowmaster 40's, intake, jet chip 2 and all my driving is city.

yea all mine it city also but shouldnt flows and jet chip and intake help your mpg?

yeah but i jsut got out of a 04 supercharged grand prix gtp, and even with the 290 hp that i was makiong at the crank, i was getting 400+ miles to a 15 gallon tank on 93 octane, i was just expecting more being that im easy on the throttle, vs. in my gtp i beat the piss out of it all the time. does the 2.7 have a maf sensor?

Man, I pulled 17.x in my RT and I get 16.x in my SRT... hardly any savings with the sixer?

[stitchmonkey]

Don't forget the weight, gear ratios have something to do with mpg too.

[equeree]

so what can i do to help the mgp? are there any sensors i can clean? does this car have a replacable fuel filter?

[cm2005300]

try using some sea foam also

[equeree]

did that already.......(seafoam) any other ideas?

Im getting close to same 210-220 miles on a tank in my sxt and I do try to drive it nice, When I first put on the intake it was really good, almost 300, now since the flowmaster and maybe because of winter it sucks!

sum weeks i get 17-19
others it seems like 13-15

bt after get an oil change it seemed to run smoother
and the mileage picked up a lil
