I don't understand why i got so high fuel consumption.
This car is new for me 911 SC -83. The emission are ok. high but it a old car. 2-2.5 liters per mil when in drive in the town. My 944 take 1 liter per mil in same drive conditions. No fuel leak as i can see. regards tom |

Sorry 1 mil is 10 KM
I think 1 mil is 6,25 miles /tom

Okay; 1liter/10km approximates 23.5 miles per US gallon and 2 to 2.5 liters/10km approximates 9.4 to 11.75 miles per US gallon. The SC will rarely if ever achieve 1 liter/10 km in urban driving conditions; however it should do better than the 9 to 12 mpg you are getting unless you are driving it a "very spirited manner" in which case the high fuel consumption might not be unusual.
Have the mixture checked and check for any misfiring; if the distributor cap, rotor, spark plug wires and spark plugs have a lot of time and kilometers on them it may be helpful to your fuel consumption to replace them. Jim |

Thanks for your input.
No missfiring and new distributor cap, rotor, spark plug wires and spark plugs. I think that the o2 sensor could be the problem. I have no record about changing history.
