4008404 Good morning. I have a pallium, year 2010, and I drive it around 1000km p/ month. With that monthly mileage, would it sompensate to put natural gas? I always fuel the car with 95% of common gasoline at one gas station, but on Thursday I fuelled at this station and now the tank is almost in the reserve. I refueled around noon, rode about 14 km and it did not present any trouble. I left in the evening, around 6pm. When I started the car, the injection light went on blinking and then it went out, in other words, it started to blink for a time and then it would go off, and that would happen again. The car had no power. The next day, when I tuned it on, the problem disappeared. What could have been it?
