Fuel Economy - What do you get out of a tank? (3rd gens only)

[SH00T]

I just replaced my 02 sensor, I drove to the workshop and the readout was 13.8 l/100 average, fitted the sensor and got 10.5 l/100 on the same return trip in more traffic.

Damn I'm doing that then. I got 15L/100km on the first tank, given I had a bit of novelty driving and I came from driving an r34 gtt skyline, but I was still pretty shocked. Need to tame my right foot I think

I only did this after knowing eberything else, about my car, leads, plugs, air filters, servicehistory, etc
And I have seem a gradual decline in economy.
At 150 a pop, I'd check it out with a multimeter beforehand.

• 145,000km on the odo
• Regularly serviced inc air filter etc

Stop-start driving in peak hour to work, I'm getting between 14.3 and 15.2 L/100km according to the trip computer.

Does this sound like something is out of whack?

If its stock, from experience maybe. O2 sensor ever changed? Whats the exhaust cond like? My GTV went upto 14l, muffler was shagged. Replaced and fuel economy went down....

If you are talking stop start as in move 100m then stop then another 100m then stop etc etc then no. If it's a bit more flowing then that your O2 sensor could be playing up. but yeah sounds very high for a fwd magna.
