    Hey everybody, I have a 93 LX auto trans and only seem to be getting 28 mpg. Is that right?? If not, what can I do to improve gas mileage. I saw on here people getting anywhere from 35-40mpg. Can I achieve that??

    around 30 MPG is about right for any escort. if u want to get even higher mileage drive like an old lady and turn ur a/c off :|

    28-32 is probably the best you're going to get driving it stock

    Gas mileage.

    I bought my 91 with gas mileage as a primary focus.
    Cheap was the next item.
    Since 99% of my driving is in town, in traffic and below 50 mph (Pizza delivery)I was focused on keeping it peppy too.
    first I got lucky with the car that presented itself...91 Pony.
    Manual steering and no options with low weight.
    Skinny tires with 35 pounds pressure. tires are very important.
    I had the oil changed and they checked the tires and dropped my pressure to 28# and I lost 4 mpg.

    Keeping it tuned and maintained was helpful.
    Driving style is important too. Give yourself an extra 5 minutes for the trip and you will find that you are not driving as aggressively.
    Slow down and drive calm....it helps!
    I am a training manager and driver so I look at all sorts of things to insure safety, economy, politeness and efficiency.

    I get about 32-35 mpg in delivery mode.
    What surprised me was when I took a highway trip of 300 miles and got 51.8 mpg.

    Replace every unboltable panel with fiberglass.
    Put lexan 1/4 windows and rear window in it.
    Take out anything you don't absolutly need.
    (A/C, Power windows, sound deadening, carpet,
    interior door panels,ect...)
    Put in the lightest replacement parts you can find
    that will be comfortable, ie...
    Light seats, Aluminum control arms, Drilled disc brakes rotors,
    aluminum wheels, ect....
    skinny tires, as skinny as you can stand and not spin
    every time you take off. And tall tires for better highway economy.

    A lot of this is comon sense. The lighter the load the less ga$oline it
    takes to get it moving and keep it moving. The less tread with to
    move the less gas.

    Make sure you have a good tuneup (new plugs/wires, properly gapped), a new O2 sensor (assuming you have lots of miles and have never changed it, and clean your MAF. With an auto...don't expect much better than 28-32.
    A 5 speed, on the other hand, will get ~3-5mpg better.

    only if you shift at the proper points :p shifting at 4k won't give better mpg ;P

    Actually this is common for people to think yet incorrect. Remember the amount of fuel going into your motor corresponds with the throttle position not the RPMs. Think of it like this: If I shift at 3k but go 80% throttle through the gears shifting at that on one tank, then the next I shift at 4k going about 30% throttle to the 4k RPM line. Which do you believe will get better mileage? 30 % throttle or 80% throttle. No more air or fuel is going into the motor at higher RPMs only when the throttle is engaged at a higher % does the Fuel/Air mixture increase.

    wow, that actually makes perfect sense >.< But at 4k and 2.5k, there is still going to be more fuel going to engine no matter how much throttle you are giving it

    Actually... no. The amount of fuel going into your motor is directly related to the amount of AIR going into your motor. The amount of air going in is related to RPM AND throtle positon.

    So when you are at 30% throttle at 4k the air is different then at 30% throttle at idle? That doesn't make sense being the butterfly is still open the same %. I figured people knew that throttle position was air, thus meaning that the throttle position ultimately decides how much air also.

    you are wrong.

    GregF422 is right.

    your engine is essentially a big complicated air pump. the throttle plate is a restriction in the intake. it can only pump X CFM of air at Y RPM. the throttle position reduces X by whatever percent it is open (not exactly, but theoretically you can look at it that way).

    so for example if your engine can flow 50 cfm at 1500 rpm, and youare at half throttle, it will flow 25cfm. and if it can flow 200 cfm at 6000 rpm then at half throttle it will flow 100cfm.

    Ok, so how is gas mileage not directly related to throttle position? More Throttle/Air= more Fuel. Meaning more Throttle wastes more gas. Maybe I'm insane but when I drive with more throttle to my 3k shift point I get worse gas mileage by 1-3MPG.

    gas mileage is directly related to the amount of fuel going into your engine (obviously), which is directly related to the amount of air going into your engine. the air/fuel ratio changes, however, based on throttle position and rpm. the ignition timing also plays a role.

    you could say that gas mileage is somewhat related to throttle position, but it is still dependant on all those other things. an engine as a system is too complicated to attribute its fuel consumption to any one variable.

    i find that if i accelerate using higher RPMs to get myself up to speed quicker, gas mileage is better than lugging my way up to speed at low rpms.

    I don't really use low RPMs I use a low % of throttle yet still send the RPMs to around 3k-3200 between first and 2nd then it varies by speed limit but only use about 20-30% throttle while accelerating.

    I said that Fuel was related to Throttle because it is being that the more air that goes in(Throttle %) means more fuel gets put in to the motor also.

    well i guess i will put my input in here.....you are saying that you are not using any more fuel at 4000 rpm at 30% throttle than you are at 2000 at 30%....that just doesnt make sense at all...at 4k the injectors are firing off the same amount of fuel twice as many times than they are at 2k. now i also know that lugging it at 1200 rpms all the time will get you bad gas mileage because you are working the engine harder than if you give it a few revs.

    Or I said that at 4k RPMs and 30% throttle it is using less then at 60% throttle, which it is. The 2nd part of your post I figured everyone knows. I guess try this experiment on your next few tanks:

    1st tank only use 20-30% throttle period, no more. After you fill up calculate mileage (right when the pump stops)

    2nd tank only use no less then 60% throttle while using the same shift points. Again calculate mielage (Right when the pump stops)

    I say right when the pump stops because some people "Top it off" and that isn't accurate. Also try to use the same pump each time.
