The heating oil that you buy for your home is not only dyed differently for tax reasons, it isn't filtered as well either. I also live in Europe and I got the idea to burn heating oil in my diesel vehicle once most people started converting (wrongly I might add) to Natural Gas from Russia. The people who converted were expected to pay a lot of money to have the remainder of their heating fuel in their heating tanks removed and destroyed as environmentally unfriendly waste. So I started pumping it out and taking it from them for free to use at home for my own use. Then I started putting some of it in my Volkswagen Passat Turbo Diesel car. It worked great for about a month, then one morning the car wouldn't start, and the dealer said the fuel injector unit was destroyed, which was something he doesn't see very often. It cost me about 2,500 Euro ($$3,000) to have a new one put in, and I thought it was just a case of a bad part. Then, about a month later, the new diesel injector unit was also bad, and they noticed that the fuel was heating oil not diesel.
