206 xt 1.6 8v 180 km with 27 liter lpg

When it comes to fuel, it makes an average of 15 lt per 100 km. Other than that, your consumption is high.

edit: sorry, your vehicle was 1.6cc. Mine is 1.4cc.

180 km with 24 liters. If you go:

24x2,80 = 67,2TL

You burn 67,2 / 180 = 0,37 TL per kilometer. Still, it was too much for me. Don't let your car leak gas?

When I switched to gas 5 minutes after cold start-up in my vehicle, it would smear gas from the map sensor section for 3 minutes. We realized it with my master very later. After repairing, my storage range is 20-30 km. I can say that it has increased. (I was driving short distance every morning. So it was very cold start = I had more gas leakage)

You should evaluate every possibility. My car's tube is 1.5 months old. I told the master who assembled in Yalova that there might be a fugitive, they could not detect it. I told another master in Bursa autosansit, they couldn't detect it either. Myself later: I discovered that he did a short-term kidnapping right after starting the cold and left my vehicle to the master in the evening. According to my instructions in the morning, when they switched the vehicle to the tube, they were able to detect the leakage. When your tank is empty again, note the mileage you have made. This is one of the healthiest measurements.
