The sometimes extreme cold for Germany cannot harm the petrol fuel. With diesel, things look different again. And the old rule of thumb can have fatal consequences for modern diesel engines.

Petrol cannot harm even extreme cold. Diesel, on the other hand, likes to be warm. Even at low temperatures, small clouds of wax crystals can form in the fuel and become a problem: If they clog the fuel filter, the engine will no longer run, explains TÜV Nord. To prevent this, some vehicles are equipped with filter heating as standard. Such a system can be retrofitted to many others.

The old rule of thumb no longer applies

In the so-called winter diesel, which is sold in the cold season, flow improvers ensure that the wax crystals do not enlarge or even form lumps. Until the 1990s, some manufacturers recommended in the operating instructions of vehicles that petrol should be added to diesel fuel to protect against frost. The TÜV experts warn against this practice. Because the mixture can cause engine damage, especially in the case of compression-ignition engines with direct injection. (dpa / tmn)
