The majority of diesel engine problems stem from contaminated fuel. Common problems include corrosion from excessive water in the fuel, micro fine particles in the fuel and improper fuel storage, which is caused by water in the fuel. There are two ways in which water can get into the fuel: through the delivery system and through the tank vent.

Fuel Contamination ~ What Can I Do?
Solution: Always purchase fuel from a reputable service provider and use a proper fuel/water separator. Periodic inspection of the vehicle’s tank vent is also recommended.

A common problem with diesel injectors is erosion of the control valve. The heart of the common rail injector is the valve through which fuel passes at extremely high pressure. The passage opening is sealed using a pressurized ball that is only 1mm in size. A proper seal is critical for exact injector performance. Abrasive contaminants, released by inadequate filtration, can erode and damage the control valve and not allowing the ball to seal. This can lead to excessive smoke, starting or idling problems and potential engine failure.

Poor Fuel Filtraton ~ What Can I Do?
Solution: To ensure exact performance within the designed service life of the injector, use only OE filters or filters having the same OE micron rating and follow the recommended OE filter change interval. Using anything less can cost you more in the long run.
