The engines installed in the car are very fond of quality fuel. So the 1.4 TSI and 2.0 TSI engines in the cold time of the year at the end of the year's unquality petrol can start triple, shut down, and not get started at all. It saves quality 98 gasoline, flushing (full) of the fuel system and reupholstery of the control unit. Diesel engines are loaded with proven fuel, and they are better equipped against the gasoline background.
