so i bought a 2000 hatch about 3 months ago for a good MPG car and
so far its been not living up to what i expected. i was thinking at least
30-38 mpg and the best ive gotten so far is 26 mpg and i cant figure out
the reason for the poor fuel economy. i changed the air filter fuel filter oil change and alignment tire pressures are always at 35. car has 84k on it and its all stock. with the exeption that its lowered on blades. should i go after the plugs wires cap and rotor next? oh yeah its an auto as well.

 

If you drive like an ***, that MPG is normal. Try the distributor cap/spark plugs/wires

 

people think i drive like an *** because im like a grandpa.

 

try changing the brand of gas for a while.

 

should i change octane or just gas

 

Try changing octane first. and if that dosent work try the gas.

 

you drive an auto.

 

Changing octane on a D16Y7 is just going to waste money. Stick with the low grade stuff. You don't need anymore and using premium is just a waste of money.

sadly enough yes.......for now

 

Why did you get an auto in the first place? If you wanted to save a little more gas you should of gotten a MT.

 

Manual will help.

I'm betting the issue lies more in the air/fuel department.

Replace the fuel filter and the primary o2. Even if you're not getting a cel for the o2 sensor, having a newer and more accurate sensor can make a big difference.

 

I Vote for the "its an auto" therory. Not like the 5sp aren't friggen slow enough the auto is like packing 5 fat guys in the car and maybe some weights in the trunk too

 

as for the a/f issue. i have already ruled that out because the LTFT is fine +6% and +/- 20% is spec. so that is fine. i think im gonna do plugs wires cap and rotor. and maybe a bottle of injector cleaner. who knows.

 

oh yeah and as for the "why did you by aand auto" question is that i got a smokin deal on the car and in pheonix its hard to find 5spds that arent all ready ruin by ricers or mexicans.

 

yea i bought a 2000 hatch as well and it was an auto but i only paid like 3 grand for it thats y i bought it. but when i had the original motor in it the gas mileage was about 25mpg and i couldnt get it any better than that so lol i didnt try getting better gas but i didnt care cause i pulled the motor out to do a b18c5 98 spec swap which is currently getting me lol 16mpg lol

 

mine will get yanked in a year or so for a gsr and tuck and i guess if you got 25 and me getting 27-29 (lately) isnt to bad.

side note===just took a trip to omaha from KC and got 31 there and 27 back???
i dunno........
