Diesel fuels by their very nature are unstable organic hydrocarbons which degrade over time depending on a multitude of factors. As a fuel breaks down over time, gums and insoluble contaminants are formed within the fuel stock. Additionally, modern diesel engines suffer from extreme levels of fuel system wear and component degradation when the water content in the fuel is above 200ppm or 0.02% (approximately 0.8 quarts per 1000 gallons). Most diesel engine OEM’s do, in fact, stipulate via their warranties that water content must not exceed this level. These factors, along with solid particulate, contribute to the majority of fuel system component wear and failures.
Diesel fuel that is not maintained correctly as close to “as refined” as possible can cause the following common problems:
- Poor starting or failure to start
- Low power from the engine
- Poor or rough idle
- Increased fuel consumption
- Excessive Smoke
- Increased emissions
