9 Mpg?!?!?!

[bjam2]

OK i'm getting between 8 and 10 mpg. I don't think thats right. My car is practically all stock with a professionally rebuild 5.0/AOD. It seems to run fine. I do practically all city driving and it is winter in michigan, but should it be this bad?

That seems really low, especially for a stock car. I have an SN95 (heavier) thats modded and even with mostly city driving and plenty of stomping on the fun pedal I usually don't ever see less than about 14-15mpg. Have you done a tune-up anytime lately?

Do you let your car warm up for extended amounts of time? That would drop it some but should'nt be that much.

i get less then that i think igot 12 on the highway doing 75

 

[5.0's 4 ever]

That is pretty bad, I get 10mpg city driving in my convertible and I have a lead foot.

 

[Ryan91Saleen]

i have 62k original miles too this sucks lol

 

[bjam2]

I don't usually let it warm up at all, cus i drive like 4 blocks to school and 5 blocks to work. Theres a lot of starting and going practically nowhere. It only has a few thousand miles on the rebuilt engine and trannie. I almost always drive it in D instead of OD cus i don't usually go fast enough to need it.

yep it is normal if u have like really bad city driving...like lots of lights and if u pull out onto main roads alot...my stang used to get 10 sometimes but usually like 11-12 or like barely 110 to a Almost tank full....and i thought it was rediculous but now im driving my sisters old car for the winter (2000 V6 camaro) and its not much better...not sure on MPG but i only get like 135-140 to a tankfull....my "city" driving is mostly on a road with alot of lights. now i go to school and am on the highway a decent amount but it really hasnt changed...i think i do TOO much BS driving lol..

 

[92BlackGT]

yikes, that horrible. I'm getting about 18 mpg in the city...all surface streets.

 

[MustangMulch]

I normally get around 14-16 mpg, and i thought that was bad! You might want to do a nice tune up.

 

[cardudeusa]

I get no worse than 18mpg with a LEAD foot.

Off topic, but Ryan91Saleen love your aviator!

 

[Ryan91Saleen]

Thanks "whytry" made it, i gae my car a tune up about 3 months ago with all msd stuff and split fire plugs.. and i still get bad gas mileage.

 

[Stalone93GT]

what temp does your car run at??

Also you might want to have your fuel pressure checked.. I was having a ton of trouble with my gas milage b/c i had to low of fuel pressure in my fuel line( it was around 20lb) and mustangs need to be around 36-39 at idle and i think it is anywhere from 45-49 at WOT.
You could start with that and also put in some injector cleaner.

[Ryan91Saleen]

i dont know lol ill have to check

 

[Stalone93GT]

Because if you dont have the right fuel pressure the injectors dont atomize the fuel right and it just dumps into your engine. That might be why you have such bad gas milage

 

[bjam2]

Uhh usually the temp gauge doesn't move, but when it gets warmed up it's usually around 190 i believe.

 

[HyPer-50]

Well... To give you a comparison, my car, which is pretty far from stock, get about 11mpg and thats with quite a heavy foot.. So ya, something is definatly wrong on your side.
