206 x line lpg fuel consumption problem

Hello friends, the lpg fuel data of my 2004 model 1.4 pejo 206 vehicle created question marks in my head, it seems to burn quite a lot according to my calculations. I have full the tank and the road I used until the end of 240 km did not seem normal to me. As a matter of fact, I took the road to the industry, they connected it to the computer, they said the setting was broken and they did it in 5 minutes with an automatic setting from the computer. Later, I fulled the vehicle again, after an average of 240 km, the tube was finished. I can understand a little if I use it in the city, but there is no traffic on the road I go, I do not stop constantly, I proceed at a standard speed until I go, an average of 70-90. Do you think this fuel consumption is normal? what should i do? what could have happened

My teacher, lpg burns around 100 km on an average of 10 liters, if your tank is 40, it takes about 32 liters of gas, so if the calculations are a little more than normal, but if the tank is 30, the calculation seemed normal.

I went to the industry, the man said that the setting of these is standard and adjusted, but the air filter and spark plug replacement can solve the problem. Has anyone made these changes and noticed the difference? dmax 2021-03-27 19:25:26

Spark plug and air filter that do not change for a long time affect the fuel, sir. but you actually need a path setting. If you want, I would also say go to engineering cordially.

Pressure lining, ignition system, intake system sensors, sensors, etc. are worn-out of every part in the engine assembly, and even the engine oil and transmission oil used have importance in the fuel. Berkay Erdinç 2021-03-30 17:07:31

After the spark plug and the air filter, I reworked the tube. I refilled my tube tank 32 liters the other day, it took 27.5 liters for 114.5 liras. There is always something in my mind that my entire tank will be 10 years old by 2022, which certainly has an effect on it, but it has been 10 years, but I've seen more cars burning less than my vehicle.

I have a 2002 model AUTOMATIC 1.4 206. I have been around for 6 years. The calculation of liter and km rather than unit price is as follows and it is not deviating.

how much gas do you get?
