I have had a few occasions when it has suited me to just get to a destination (or get home) and I have driven the van for around 24 hours only stopping for fuel and to make up fresh flasks of coffee. You can get a long way from Calais very quickly eg Sweden or Portugal and I have another trip coming up where I will probably do the same. I understand the issues for the driver, however, something made me think about the van. Does it do a vehicle any harm to be run continuously for that sort of time? I know lorries do very long distance, however, they do have to stop regularly in line with the countries working time directive. Guess my thoughts were does it impact on the dpf or egr or oil degregration etc?
