The modern diesel engine is designed to burn clean diesel fuel only, unlike older diesel engines that would burn almost any type of oil (peanut oil, kerosene, waste oil and the like) The reason why modern engines are more finicky is: the pumps and injectors have much closer tolerances.

Always check the manufactures recommendations for any use of biodiesel. Some will only allow 5% and other as much as 20%. Use caution with fuel dry additives, they contain alcohol. Alcohol can change the flash point of the fuel and cause damage to the engine. Diesel fuel storage tanks can develop microbials and asphaltenes if water is present. These fungi strive on organic fuel and since diesel is an organic fuel, it provides and ideal environment for bacteria to feed and grow. This contamination will clog fuel tank socks and fuel filters with a black substance.
