The average cost of petrol per city depends on the volume of the engine, the type of check-check, the ways of driving, the petrol and air conditioning. The owner of Peugeot 207 notes that the average urban cost is between 7 and 11 litres. 100 km. In case of a sharp increase in flow rate, if this is not due to a change in driving behaviour, air conditioning or long running of the engine, you can:
-to try changing the gas station (possibly a high consumption is related to a fuel-efficient fuel);
-check the condition and, if necessary, replace candles;
-to clean the throttle;
-to wash the injector.
