why worry about it?

Contamination control is increasingly important for maximizing fuel economy, engine performance and service life, as well as minimizing emissions. Some Cat® fuel systems operate under extremely high pressures and meet tolerances smaller than five microns between parts. This makes fuel systems more vulnerable to the wear and abrasion caused by fuel contamination. To minimize contamination in your fuel systems, follow these guidelines:

Use clean fuel – Contaminants can enter fuel during storage and transportation. To minimize contamination, use a reliable fuel supplier, filtered dispensing and periodic sampling to ensure fuel quality.

Keep fuel tank vents clean – Airborne particles can be drawn into a fuel tank through an improperly sealed vent tube. Check vent tubes regularly and keep the area around them clean and clear of foreign matter.

Utilize clean maintenance practices – Contamination can enter fuel systems during maintenance and service, even when doing something as routine as changing filters. Keep engine compartments and service areas clean.

Use high-quality fuel filters – Cat Advanced High Efficiency Fuel Filters use exclusively designed filtration media to remove 98% of particles four microns in size and larger. Other brands of filters provide efficiency levels as low as 50%.

Measuring Contamination

A particle as small as five microns can damage fuel systems. One micron is one-millionth of a meter. To provide an idea of just how small that is, an average human hair is 80 microns in diameter as represented by the yellow circle.

Sources of Contamination
  • In the fuel – Contaminants can enter during storage or transportation of fuel. A reliable supplier, filtered dispensing and periodic sampling and testing assure consistent quality.
  • During Operation – Airborne particles can be drawn into your fuel tank through the vent tube. A fuel tank can ingest dust when it is not properly sealed.
  • External – Contamination can enter during maintenance and service, even when changing filters.
