how's your fuel mileage?

[Voith]

My NA uses app. 10~11L / 100km if I drive it fast. if slow it gets to somewhat 8~9L /100km

I use 100 octane gas only.

Because we tried to throw out everything except for the language in 1776.

My car seems to run good, but I only get about 20-23...and I live in the country, most of my driving is open road.. When i mash on it, i can smell exhaust, and there is some soot on the tail pipe.. whats the most common problem?.. The O2 sensor doesnt surge or pulse..

[nynor]

vacuum leaks, bad O2 sensor, bad spark plugs, weak spark, bad FPR/dampener, leaking injectors.

[Lexluther]

Is it possible for the injectors to "dribble" into the cylinders after I park it? IThe car runs pretty good, but sometimes after it sits for a coupled days, when i go to start it , it runs rough and then smooths out after a couple minutes... if it smokes any its very faint black or grayish.

[nynor]

yeah, they can. also, the backflow valve at the pump may be bad, or the cold start equipment isn't working right.

[Lexluther]

Well it starts easy, crank a few times and it starts right up, just after a few days sitting it idles rough and smoothes out, once warm it idles fine. I think I'll check out the o2 first. Already changed the plugs and airfilter and such.

[Lexluther]

I tried to get the O2 out, no luck!! its really in there, I even went and bought a tool... it looks like its been in there a while. I'd say theres a good chance its bad.

[nynor]

they can get good and stuck, for sure.

[Lexluther]

Any tricks to getting them out? I am afraid i'll take the threads out with it.

[nynor]

dose it really good with penetrating oil, let it sit overnight and try again. i doubt you will take the threads out, but it is a worry.

[Lexluther]

I took the threads out of a BMW once, kinda gun shy about them now.

[callmethewander]

no matter how i drive my '87 NA i consistently get 23.0-23.6 mpg, not that great.

[Aufgeladen944]

I average around 22 with my 951. If I engage the turbo WOT, it dips down significantly.

[Dave101]

I get about 25 pr gallon but I also drive like a fool most of the time. Its so much fun to drive fast that i can hardly test it going a normal speed hehehehe

[exitwound]

Do you MPG gauges factor into this at all? Are you doing miles/tank by absolute values on the odometer? I'm asking because I wish to know if the MPG meter is accurate within a few MPG or whether it's just for fun to watch bob back and forth.

i get about 16 MPG in the city, due to my heavy foot and boost-dependence (its a problem, but i am not seeking help!). on the highway, averaging 80+ MPH, i get about 26-27 MPG.

[mattdavis11]

25 with the A/C on, 31-32 off, mixed. Not a lead foot.

[Lexluther]

OK, I got my O2 sensor out today, will change it tommorrow, i talked to my brother he said it might be the coolant temp sensor....he seems to think it would make more of a gas mileage difference than the O2.. Any thoughts about this?

[nynor]

yeah, it could. if it was 'stuck' reading that things were cold, i guess the computer would be constantly dumping fuel to make things rich for cold running.
