How bad is your MPG?

[DatUtahGuy]

this thread makes me feel better about myself

.. i thought my car was the only one ... but i didnt expect prius status from a 6 cylinder ...

my car has been running like crap .. with black suttt covering basically the whole rear end ....

lies! you got no feelers

18 city, 22-24 freeway usually - M20B25

[MG325i]

O mpg.

i laughed when i saw this, cause this is what mine says since my speedometer doesnt work
but i get about 300miles with a full tank of gas

[dude8383]

I'm averaging 20mpg with my untuned 24V.

I hope that number goes up when I do get it tuned.

I've been able to squeeze out 239 miles on my 14.5 gallon tank, I filled up around 11 gallons though.

3.0 liter stroker

driving easy
18-20mpg, mostly highway

[Moto-Mucci]

jesus. somethings def. wrong.

Is the OBC MPG read out usually accurate? That's what I've been going by. I need to do it manually and check I guess.

28-30 Combined on the old M10, Starts right up every morning in the single digit weather... couldn't be more happy with it.

I get the same. 26 if I really romp on it. No OBC, straight odometer/fill up calculations for me. Its great compared to my full size Chevy truck - 13mpg or so city, 18 highway - mid 15 combined. I can granny my R6 along my commute to a whopping 52mpg though, so summer time means the bike wins.

[Moto-Mucci]

yea, I'm trying to pick up an R65 for the summer. I want one so bad.

I get 23-25 mixed driving. San Diego is a little hilly too. 16x8 wheels and decently sticky tires. I should go back to bottlecaps, I always got a few extra days of driving when I had them.

lol my obc says 29-32 mpg avg, way inaccurate, especially with diff injectors

[jflip2002]

I get like 22 mpg in the 325is, but it has the 410 diff, so Im not sure how much that negatively impacts the fuel economy. It is definitely a little dissapointing, though.

[Kruzen]

150 to a tank if i'm commuting through the city, ~420 to the tank if i'm on the freeway

[AndrewBird]

I, like the OP, am also getting about 15 city and 20 highway. and that is with a 318i! I can't figure out what is wrong for the life of me!

I replaced the air filter, changed distributor cap, O2 sensor, rotor, ignition wires, spark plugs, re-timed, oil changed, tire pressure ok , I can't figure out what the problem is! I drive pretty well also, I never accelerate when it isn't necessary.

Does anybody know what the problem could be?

How about the temp sender for the ECU. I know it has an affect on mixture when cold. Not sure if being faulty would cause a rich mixture at normal temps however.

Also, he meant temperature not as in how you warm the car up, but how warm the car gets. A low temp thermostat will make the car run cooler, sometimes too cold.

[2002maniac]

My 318is with cams, markD chip, and exhaust would get 25-30 mixed hwy/city

and outrun my brothers stock 325i (gets around 20mpg)

M42 ftw!!1!!

[UmmYeahOk]

Mine is 19mpg 100% city. Original spark plug wires, distributor and injectors. Odometer doesnt work so I have to trust my OBCs calculations. I thought it was hilarious when I was watching a cadillac esclade hybrid commercial. It was trying to make people think that it got better gas mileage than a toyota prius. Like they were in the same market. Anyway they somehow claimed it got 19mpg (clearly the prius gets more than that, and even the escalade gets 20) anyway since they said 19, I was like DAAAAMN! My 21 year old sports car gets better gas mileage!!!

BTW, how long does it take for you to crank the car before it starts? Mine takes a while, and sometimes it wont start at all unless I give it a little gas.
