206 xdesign lpg consumption is too high (help)

Hello friends, I have the 2006 model xdesign 1.4. an atiker sequential system is installed on it.
I will go about 20km between work and home every day.
As LPG consumption has increased recently, I have been able to travel only 95 kilometers with an average of 30 TL (13.57 liters) (20 km from the city). According to the account, I consumed almost 30 kurus per km. Before 1 month & nbsp; Until this consumption was 20-22 cents. I wonder why the values have increased so suddenly. Thank you in advance for those who can help. I wish everyone good forums.

When did you last maintenance the vehicle? Have any parts changed in the exhaust or engine system?

The last maintenance of the vehicle was made in May 2011. No changes were made to the engine and exhaust.

My brother Mustafa has the same problem, I had an abart, I inserted him, I put on his original exhaust, and he traveled 50 km with 20 TL :)

I had a very burning problem too, go to the lpg service and have the hoses checked, splitting, cracking, and if you clean the air filter, you will get very good results. When they connect it to the computer, they make some adjustments and book them too. I went to Antalya last week, I went from Antalya to Kütahya, and made the calculations for about 400 km.

The fuel system of the vehicle and the factors that will affect it should be examined by a good master. I don't like LPG at all.
