Which type of oil contaminant originates from engine component wear and tear?

• Water contaminants

• Dirt particles

• Metallic wear particles

• Biological contaminants

Oxidation by-products form as a result of oil reacting with:

• Fuel contaminants

• Water

• Oxygen

• Metallic wear

Fuel contamination in oil systems can cause which of the following effects?

• Increased oil viscosity

• Decreased lubricating film effectiveness

• Formation of varnish

• Lower biological growth.

Incomplete combustion and engine blow-by can produce which contaminant?

• Soot and asphaltenes

• Bacteria

• Rust particles

• Sludge and unburn gasses

Biological contaminants in oil systems typically form in the presence of:

• Oxygen and asphaltenes

• Metallic particles and oxidation

• Water and organic matter

• Combustion by-products

Which method is crucial for preventing oil contamination in marine systems?

• Reducing oxygen exposure

• Proper filtration, purification, and monitoring

• Limiting fuel usage

• Enhancing asphaltene levels
