gas mileage Options

[DomGT]

well yeah, i was driving around today right, and than i get an empty tank so i go fill it up with exacly 1 gallon.

i got like 20 mpg before the car started to die on me

is 20 mpg bad on a gt?

Why would you do this to figure out your gas mileage? Running out of gas is very bad for your motor. Any and all sediment on the bottom of your fuel tank has been sucked up, has clogged your fuel filter, and anything that made it through the filter, has combusted in the engine. If you need a better way to figure out MPG, PM me, I'd be happy to tell you.

engine is stock.

check engine light is on

damn it ima try to get it scanned today!

thats on 87 too, should i try 89 next and see if i get a difference?

I just read this post... CHECK ENGINE light! Read my previous post to see WHY your check engine light is on.

lewfx can save the day, i got a fuel filter, o2 sensor, plugs, and tools

[nightryder]

changing the octane is not enough of a difference to make your mpg normal. Id get that thing checked at an autozone or something, they do it for free. but IMO, its prob an o2 sensor, those things are a b****

good call Dom. Its much better for the car to do a complete fill up, set the tripometer then go til the light comes on , take those miles, and divide them by the number of gallons in the tank. that way you wont "suck bottom"

Running out of gas is also bad for your fuel pump. Your fuel pump is located in the fuel tank so that the fuel keeps the pump cool. If you have no or low fuel, there's nothing else to cool the fuel pump so it heats up. This cuts down the life of your fuel pump. So the best way to keep your fuel pump lasting longer is to keep your tank full , well maybe it doesn't have to be on FULL, but atleast have a good amount in your tank haha.

ive noticed better mpg when ive switched to 91and 93, 89 is just crap

[MaskedMan]

Well the octane shouldn't really affect mpg, our cars (and i mean N/A models) should run better on 87 or 89 than it would on 91 or higher. The only difference in the octane rating is how resistant it is to combustion. The higher octane, the more it takes to ignite it. That is why Turbo and high compression cars run higher octane gas becuase running higher octance just decreases the chance of detonation, or a misfire. Um i just went to get some food and came back and forget what i was talking about, so thats all you get haha

Just to help everyone out that is reading this thread, lets go over all the parts that are damaged by running out of gas:

Engine
Fuel Filter
Fuel Pump
O2 Sensors

Keep on adding to the list!

spark plugs, wires, distributor cap and rotor, IAC needs a cleaning, clogged air filter, etc

well teh celi Literally lives on empty.

i dont think the mother has ever filled any of our cars up.

Okay now your just f***ing with me. I know... it shouldn't bother me, its not MY car but... just the thought of ALL the parts on YOUR Celica screaming for dear life... almost brings a tear to my eye. All I can say is that your car hates you. Don't sell it, please?

I wish I got 20 MPG

[Kadett]

Always fun to see a topic like this started when there are about 10 of them around.

My Milage
3S-GE : 20-24MPG (City/highway)
3S-GTE: 22-33 (City/hihgway)

[DomGT]

3S-GTE: 22-33 (City/hihgway)

Gotta love turbo lag. I too get over 30mpg on the highway in my VR-4.

Which turbo lag??? Ive driven the car with the 3s-ge of course. And it behaves just like a 3s-ge untill you get to around 3000 rpm and start to think there is something done in the engine bay

[Daftboy]

I seem to get about 28 MPG with 92 octane....

[XS4lv1Truch0x]

wuttt 33 on a 3sgte!!! wow thats impressive.

lol econo warriors!

[jess_i_74]

29 on a GT convertible. 35 on a ST hatch. both manual.

You could start by checking your O2 sensors. Whether it would be 1 or 2 sensors, it might have gone bad that's why your check engine light is on and your fuel mileage is bad (Happened to my car when I had the 7AFE motor in it). Change those and...then get a tune up. That should fix your problem.
