The diesel fuel system is a very fine tolerance operating hydraulic system which requires fuel to be of the correct type and viscosity to ensure full operation, performance and drivability of the diesel engine. Both petrol and water are NOT in the category of lubricant fluids for a diesel fuel system. When the incorrect fluids have not been removed before the engine is started, in a short period time, approximately 24 hours, the damage will begin to occur.
