14.4l/100km

Hey, I'm wondering if this is to be expected from an '87 2.5L engine (M20), but I'm getting about 14.4L/100km. (that's 16.3 MPG)

Post what you get and what things that you think could be done to improve this. It's a DD and I'm trying to get it more drivable. (less gas chugging)

Thats pretty high. I used to get 8-10l/100km on my m20. How is your O2 sensor? They will kill mileage. My m42 does around 7-9

My gt35 powered volvo 5cyl uses around 12l/100kms in city driving. With 22psi and a heavy foot.

O2 Sensor is old, I guess that could be a starting point to replace? I'm looking at 122$ from BavAuto. Maybe I'll just pull one from my friend's parts car. (has <100k kms on it)
