3. Can light fuel oil be used to drive diesel engines?
Although the physicochemical properties of fuel oil allow it to be used to power diesel engines, however, due to tax regulations, it is tantamount to having to pay the difference in excise duty to the tax office.
Some people write in such a way as if driving on the company's diesel has never caused any failure of the engine and accessories, and all that comes down is the fault of the fuel. I used only the legal for a long time and also replaced the injectors, my fuel filter was clogged with crap and paraffin because they changed the price to a winter one, but they were still selling the oil in summer. The engine wears out with age and normally breakdowns also happen. I will slowly try to change supplier
because it's already 3.38 and I won't last a long time and either the car is pegged and I am on the bike. Or ..... None of my clients do not want to accept the argument on my part that I have to raise the prices of my services because the fuel price has become more expensive, so I have no choice:? Such a world, though somehow I am not happy about it

It's enough to find a guy who drives trucks or in PKS, because I know that they trade crude oil for 2.5 (today's price). I did it and I hope I will buy from him as much as possible and he will continue to trade!
