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. :mrgreen:

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!

Mine is a brand new 07 Charger with 2000 miles on her and I’m seeing 380-450 a tank so far. That is what I was expecting to see; that’s why I bought the small motor .. that is the mileage you should be getting based on the window sticker .. I’ve got to say I’m sure glad it’s getting the mileage it is because otherwise it would not have been a good choice to buy this car as a work vehicle ..
