An autogas system means that a vehicle uses liquefied petroleum gas (LPG) instead of gasoline. The autogas system has many benefits:

1. Economic Advantage: Autogas is a cheaper alternative to gasoline and diesel fuel. LPG's price per liter is generally lower than gasoline, which provides car owners with significant savings in fuel costs.

2. Environmentally Friendly: It provides a cleaner combustion compared to autogas, gasoline and diesel fuels. As a result of the combustion of LPG, less harmful emissions are released into the atmosphere. Therefore, using an autogas system contributes to reducing environmental pollution.

3. Performance: The combustion characteristics of autogas do not allow power generation as high as gasoline or diesel fuels. However, modern autogas systems have been developed to minimize the performance loss of vehicles. That is, when you switch to the autogas system, you will not feel a significant decrease in the performance of your vehicle.

4. Fuel Range: A vehicle with autogas and petrol system has the ability to use both. This increases the vehicle's range and provides greater flexibility on long journeys. In addition, you can travel using LPG in cases where there is no gas station.

5. Engine Life: Compared to autogas, gasoline and diesel fuels, it creates less wear on the cylinders. This contributes to longer engine life and less maintenance.

6. Partial Sequence Fuel Injection (LPG+Petrol): Some autogas systems offer partial sequential fuel injection to vehicles. In this system, the vehicle uses both LPG and gasoline. In this way, the vehicle's performance and fuel economy are optimized.

These benefits are the main reasons driving the popularity of the autogas system.
