Hey everyone, Im new to the forum and I own a 1993 325i, its got about 105k mi. on it. I think it has a cithip and I know it has a K&N filter system. I recently bought this car and changed the oil and oil filter and spark plugs. The reason im posting is because my gas goes at about 9mpg. I just filTled up the tank with 93 octane and I barely went about 25mi. and its almost eaten up a quarter tank. Can anyone help me out with this and enlighten me on what other things I should worry about? Thanks

One more thing, when I read the digital display and odometer, it shows the mpg on the streets to be about 24mpg but it seems like 9mpg.

Wow 13-21 mpg?

Weird, this morning I tripped the mpg consumption key and I was getting 28-31 mpg on the freeway. I normally get 350-390 miles a tank.

Either you something wrong with your car or you got a LEAD FOOT!

Trying filling up the tank and using all of it a few times and get an average.. when i fill up my car the first quarter goes really fast but then the middle portion remains there for a while... sometimes, the guages are funny... so don't panic and give it a few full tank runs if you haven't already done so...

Now looking for an M3

Keep in mind, the gas gauge isn't necessarily accurate. It just indicates ROUGHLY how much gas is in there. I would stop at a gas station, fill it up, and see how much gas has really been used.

You need to suck it up and actually break out a calculator and figure it out. Fill it up, go for one of those 25mi test drives, then go back to pump and top it back off. Divide the fillup by the mileage driven.

Don't bother reading the gas gauge.... its just an appromixation. The first quarter on my Grand National takes a 100 miles to go through, and the next 3/4 go in 75.

on my 328 I tend to get high teens city only, and upto 30 on the highway.... if your stomping on the pedal, and driving city only I can see #'s in the low to mid teens as a possibility.

As a side note, I can usually get about (a little less than) 400miles out of my tank (e36, 15 gallons not including reserve) without dipping into reserve. However, if I floor it, the needle visibliy dips... heh...

Anyway, main point, also realize that fuel gauges are also a bit finicky in terms of what they are really showing you; they're kind of messed around with - fuel guages on the whole (some may be different) will tend to linger on full, quickly drop to half, linger on half, drop quick to a quarter, linger, and then drop to linger near E when the reserve light goes on leaving you with 2 gallons. So that 25 miles down a quarter might just LOOK like a quarter; keep driving and if it goes past the halfway mark without slowing/pausing at the halfway, maybe you ARE consuming that much gas.


Crap, I think I may be a yuppie...

First off, the best way to measure, is by using the paper, pencil and calculator method when refueling.

What probably is happening is that your fuel level sender is bad, and so it suddenly drops from full to a quarter tank like on a blink of eyes.

If the digital read out gives of like 24, ure good. The digital readout calculates comsuption by miles driven over actual fuel burnt, this is possible, since the DME can calculate how fuel has been burned for the miles driven. and then it displays the results on dash.
This is possible because fuel injector work on a regulated pressure and are rated for flow. With this, the DME can know how much fuel was injected based on how long the injector was open and for how many times..

Is rather complicated, but is all calculator stuff, pretty simple for that DME unit.

Reason i say this, is because ive been working with Motec, and this is how we calculate the amount of fuel being burned for each speed, is not complicated, but you need to look at it carefully.
