is that bad? Fuel light -> Full -> Fuel light, 161.4 miles. Isnt the stock tank size like 16 gallons? so im getting 10mpg? This is mostly city driving with a little highway here and there, not very hard driving.

 

How much do you put in when you fill it up? Its fairly likely the gauge is off. Always compute MPG based on Milage Traveled on Tank/Gallons put in tank (Miles/Gallons)

 

you need to look at how many gallons you pumped back IN to the car. I know my gauge likes to fall off quick but around 1/4 I have about 6 gallons left in the tank... so, there ya go.

Yeah from the "E" on mine I have roughly 2 gallons left. I'm getting about 14-17mpg.

 

Do like they say, set your trip odometer to '0' at the next fill up. Then next time you fill up see how many gallons you put in. and look and see what the odometer now shows. Take your mileage on the trip odometer and divide by the number of gallons and that will give you mpg. 10mpg is horrible. I get 21 in the city.

You shouldn't run until the Fuel light comes on. Your entire fuel pump needs to be submerged in gas for cooling. Im not sure if you go below the Fuel light it will be submerged.

 

You get 21 in the city? I'm lucky to get that on a highway, whats your secret?

 

seriously 21, i get like 15-18mpg in the city. if i go freeway i get into the 20s but let us in on ur secret??

 

d00ds he prolly uses that tornado thing they sell at autozone... you have seen it... it adds HP and fuel economy like a f'n magic bean or something.

hehe

 

you mean that isnt normal?
when my guage is on empty (and the gas light comes on under cornering) i usually have to fill 12 gallons up

only get about 150-170 miles, too

 

My S4 NA gets ~260 miles to a tank with at least one redline a day wiht 70% of that on the freeway. I average 17-19mpg.

 

check compression... i have no compression on my rear rotor and i get 160-170 miles to a full tank.. just a thought.

 

Yea I get around that as well, but instead of 170, I can sometimes get up to 185.

 

I used to get really good mileage with my auto. SE, around 26 city, and 28 highway. Im not really sure how that worked out, but I wasn't complaining. My TII on the other hand was a gas *****, probably around 14 city.

 

THATS THE BOOST BABY!!!!! YEAH!!!!

lol

 

my car is carbed and oversized jets i believe not too sure brought the car as a challenge, and its a big one since i get 8 miles to the gallon... i ran 80 miles and felt like filling up... man, 9.8XX gallons i thought my needle was wrong.

 

Sounds about normal to me... I generally let my gauge fall between 1/4 and E... usually closer to E, and I usually end up pumping 12-13 gallons. I think the original poster was thinking he was running his tank nearly empty and getting really horrible fuel mileage. In fact, it's probably about normal since he probably isn't using all the fuel in his tank. Anyways, this thread is a dead horse now

Oh yeah.. and I have a white 87NA that was being a bitch earlier and it usually gets about 15-17mpg.. but i drove on tha highway for ~250 miles and i STILL have 1/4 tank left. Why do these cars get shitty gas mileage? Those that suffer are too ignorant to care, and those that don't have already fixed whatever causes it.

 

im a newb to the whole rotary thing...i may still be ignorant about it but id like to learn....how can i make mine better? im getting crap mileage! i was used to getting 25-30mpg in my 240, now im getting roughly 12-15mpg in my N/A FC.

 

stay out of boost and if you drive around the city youll get 15-17mpg just like me!!!!


but hey what do you expect your not driving a civic... heck your not even driving a v8 from the 2000s because even v8s these days get better mpg then our mid-eighties designed sports car

 

Do a tune up.

 

10MPG, really rich. Btw you can check your spark plugs and injectors for those looking for a better efficiency.

 

I get 23MPG on the highway and 15-19 in town, I didn't think its that bad .

 

12 mpg city, 15 highway...damn upgraded turbos or something...my car was just tuned too On my way to LA with a quick self tune my car got 16 mpg and was running rich...now I get 15 highway if I'm lucky and had it tuned

 

yeah i get like 10 miles to the gallon. i once filled it up and i swear i never went over 4 rpm and only got 200 miles on that trip. sucks!!!

 

nah, im running NA...i just bought new spark plugs and im gonna check my injectors too. hopefully that will help it out a bit. maybe this will solve my problem of me running rich as hell =/ when i 1st got the car about 2 weeks ago it reaked of burning gas inside the car and after i got new exhaust and put a new cat on it, it solved that problem.
