You're doing about 20 to the gallon there. Not sure what it should be as mines not on the road yet and I've never run one before.

[Brianmoooore]

Should be around 26 MPG for a 325.
Spark plug colour check is the first thing to do.

[Joe-318i]

that sounds good, i put £30 in my 316i tourer and got 90-100miles when the red light came back on, is that good or bad ??

[e30scotty]

well i am carrying out a service on wed so i'll have a look....
cheers fella i'll let ya know what i found...

[e30topless]

depends how heavy your right foot is .. your getting the same mileage I do roughly,

[Joe-318i]

thats just what i would call normal driving, to work and back

[kam-325i]

Around town i get about 22-25Mpg

[m4xos]

if i boot my 318is now, i have petrol pissing out the exhaust pipe, wwaayyyy toooo much petrol going throw the engine!!

[suchy]

I'm lucky to hit 200miles to £50!! But mine is out a 'bit' so yeah 253 is about right for steady driving
It's the price you pay for that lovely sound

[LeonNewton]

iv just come back to e30s after a stint with landrovers. in both my 318is and my landy i get 300 ish miles for a tank. the landy costs £100 to £130 though. i like my eco bmw

[DaveD]

It costs me £30 for 200miles which is about 26 mpg round town nd about 34mpg on a run ...325cab

[StuB]

I tend to average about 21mpg on my short daily commute in an E30 325i Sport. On longer trips with steady motorway / A-road runs more like high 20's. Yours sounds about right to be honest.

[BruceVeedub]

I only get about 175 miles out of a full tank in my 325i cab but it is mainly stop start stuff to work and back every day, don't even think she gets chance to warm up properly. A service is well overdue though I think. Just need to remember where I parked it on Sunday night ow as it's under about a foot of snow

[pnd]

I have just got 370 miles out of a full tank on an 88 325with the red light having been on for 10 miles but most of this was motorway driving.Later 325's do about 25-27 on mixed driving if you aren't gettinng this it may need maintenance have you changed the blue coolant sensor?

[DaveD]

here you are...some previous results

[gingebmx]

I read somewhere that the engine earth strap can go home on E30s which causes the ECU to make the car run rich, just another thing to check.
I get 25ish mpg from my early 325 sport and thats mixed driving

[powelly]

I just got about 200 miles out of a tank on my '89' 325i, in all honesty though I don't exactly drive it economically all the time, it also has a speedtouch mild chip fitted, I may well change this back to the standard one to see if there is a difference, the exhaust smells like it's over fuelling quite a lot.

[BigBavarian]

M50b2.5 £40 gets me almost 200miles if im lucky, driving carefully, boot it and im lucky to see 150miles

[djk]

Mixed driving should see high twenties. I check my mpg every time I fill up on my daily driver 320i - Best 38mpg, worst 21mpg, based on the odo reading. Economy seems to be worse with a speedtouch mild chip.
