Are you kidding me? Thats BAD.

When I first got the car I was getting good gas mileage but with my mods I've lost a good bit.

 

its different when u live in the city..brooklyn for me.

stop signs and traffic lights about every block or two..

stop and go FTL

 

try using a different gas company. some stories i heard before people went from cheveron to 76 and saw an improvement in gas

 

heavy chrome wheels will kill your mileage. And any heavy rotational part, for that matter... if you got any that is.

 

+1. i do 95% city driving and usually average 16-18mpg. its not bad though since i only have to fill up once a week at most.

 

i would check ur tires. i didnt then i was like wth am i getting low miles (i average 21-24 but i was only getting 18-19) no driving habbits changed.. all tires were 28-30 O_o ooops? hah

 

I know this sounds simple but a really dirty air filter will almost double your gas mileage. I owned a Mazda B2200 for sixteen years for a period of about two years I forgot to change the air filter and I was driving in dusty conditions. The little 4 banger was sucking gas like a V8. I just thought the injectors were worn.
I checked the air filter and dropped it in the drive way to see how much dust would fall out and I got about a cups worth. I was shocked, how could I be so stupid. I put in a new filter and voila, gas mileage went back to normal. I still drive the truck too, but not as much as my G.

 

Just got 320 miles on a tank-thats with 7 drag races at the strip!

 

I used to get around 14mpg on my G, but after I put the s/c on it only comes out to about 8mpg, and I dont event drive my car that hard. I get about 140mi on a full tank.

 

That is 16 miles a gallon, which isn't much worse than my 16-17 I normally get just for in town driving (most trips 4 1/2 miles each way to/from work).

Do you use AAA? When you get to 320 miles, and the car sputters to a stop, I assume you need some gas delivered.

 

you should move to Venezuela where gas costs 18 cents a gallon

 

i thought venezuela was 12cents? i know usa is # 44 out of 155 on cheapest gas hah.

 

Can't believe no one mentioned having the fuel system professionally serviced... About every 25K I take my G to NTB where they do a proper pressurized fuel system cleaning and I pick up a few MPG instantly as well as a good power increase... Over the miles it drops again and I go back to NTB for the service...
Try this with a reputable shop; I highly recommend it every 25-30K

 

i get 10.5 mpg NO JOKE on my 01 jeep grand cherokee, dont complain till u have a V8 haha, cant wait to get 14.7 in a g35

 

Wow, some of you guys are low. I'm getting about 20.9 mpg (says the navi) and I'm shifting between 3000-3500 rpm.
