The Effect of Fuel Contamination on the Wear .

totally deteriorating at 7%. Wear scar diameter is found increasing with the increase of fuel contamination. In addition, the wear scar diameter depends on many factors such as load, temperature, speed and properties of the lubricant. Some oils have lower coefficient of friction but produce higher wear scars such as RBD palm olein oil.
