The use of vehicle petrol (conventional or E10) generally causes greater contamination of the nozzles due to the additives, as well as greater stress and ageing of the seals. Therefore, if the use of vehicle petrol is being considered, a wear parts set (nozzle, seals and tools) should always be taken along for the respective device.
