MPG

[Bill 84 318i]

I don't keep track of it or anything, but it's not like the little math equation is that difficult to do on your way back from paying the ugly lady behind the counter.

exactly, i don't have a little book i keep track of them or a calculator i keep in my car, i just do the equation in the car or whenever have some spare time to think about it. I just like to know how wasteful my car is being.

yeah its not to hard to do real quick in your head a 14g fill and 300 miles on the tank, = 21mpg, not to hard. Just push the trip odometer every time you fill up and wham there is the mileage

btw how big is the e30 gas tank, i don't think i've ever put more than 11 gal in it.

[nando]

depends on your car. some e30s have smaller tanks than others. I think mine is 16.5 gallons.

[KenC]

I put 12 gallons in once when the reserve light was on.

[nando]

yeah you probably have the smaller tank. I think it's around 14 gallons. I usually put 15 in when I fill up. :)

I looked at my obc when i first got the car and it said 11, and i was goin crazy, then i realized it was in liters, and also in kilometers. Is that how all obc's are, because its really annoying. this is my first e30 with an obc, so i dont know much about it. also i need to change the light in it, is there a write up on that by anychance. I plan on changin it when i put my new headunit in. thanks

To change the light this should help, it's real easy but the backlight costs like $30 or something crazy. http://www.r3vlimited.com/Tech/OBC.htm

To change the readings from Metric to Standard, push the MPG button and then push the small pin hole on the bottom right of the OBC. hope that helps.

[BavarianBimmer]

mostly i've got 28 MPG with my 318
and can fill my tank approx wiith 12 gal

my 2.7 has a big 18 MPG but it's not a daily driver so why matter

but you US guys have cheap gas
I can pay $4 a gallon for 98oct and $3.90 for 95oct

I get probably 28 in my eta. My OBC is a little messed up. It tells me im getting 25.5, which it probably does sometimes. My fuel gage also likes to jump around a lot. If I take a turn a certain way or park on an incline i will either gain or lose a 1/8 tank. Any ideas on that one? It usually is close enough for me to know and i tend to fill up around 300 miles.

[eliasmavs99]

On 3 hour trips my mpg starts at 28-32 but after I hit a couple of lights and accelerate back to cruising speed it stays at 26-27 the rest of the trip. Any ideas?
