About us

Auto gas Kotlajić

Auto gas Kotlajić is a family company, with over 40 years of experience in installing LPG and CNG devices. The beginnings were in the 80’s of the last century, as a hobby of our main master Lazar, who passed on his knowledge and research in that time for a little-known fuel to his sons, who still form a real team together with him. The quality of our work is known throughout the entire territory of Serbia. We also get positive impressions from the territory of the former Yugoslavia, Germany and other countries in the region, which is shown by the data on the renewed cooperation of satisfied clients from those areas.
