    Hello, everything that is described here is only half-knowledge, you should ask people who had experience with it. I myself am 30000km in the 190D. Driven pure salad oil without modification. Regardless of whether it is rapeseed or sunflower oil. No problem. Even in winter the car drove without any problems. In very cold temperatures you just have to let it warm up for a few minutes. No seals were broken, no hoses broken, nothing. The only thing you had to do was change the diesel filter every 6000km.

    Vegetable oil is a food and is taxed and must not be taxed twice. That's why it's not tax evasion! Otherwise they would have withdrawn all PÖL vehicles at the time. But then they found another option. Within just 6 months, the PÖL was just as expensive as the diesel. What a coincidence !!!
