General maintenance information Truck stops have pumps and nozzles designed for larger, heavy-duty trucks. When refueling at truck stops: if the nozzle shuts off repeatedly when refueling, wait 5-10 seconds; then use a slower rate of flow (don't depress the nozzle trigger as far). If air is allowed to enter the fuel system (during fuel filter change or if you run out of fuel) the engine will purge the trapped air as it runs. The engine may run rough and produce white smoke while air is in the system. This is normal and should correct itself in a short time. An engine that suddenly becomes noisy or operates poorly after a fuel fill could be using substandard fuel (i.e., high water content, low cetane rating or gasoline in the fuel). Diesel fuel should be purchased from a reputable station which sells a large amount of diesel fuel. Care should be taken whenever diesel fuel is stored. Use only clean, approved containers which will prevent the entry of dirt or water. Diesel fuel must not be stored in a galvanized container. The fuel will dissolve the zinc in a galvanized container. The zinc will then remain in solution until it is run through the engine where it will be deposited in the fuel injectors causing expensive-to-repair damage. 17
