The worst case scenario occurs when a modern diesel engine is started up using petrol or premi‐
um-grade fuel. Because these types of fuel lack the special lubricating properties of diesel, it is pri‐
marily the precision components in the injection system that will be irreparably damaged. Secon‐
dary damage may occur to the drive engine.
Example: Machine with diesel
engine
