| contamination |
water, antifreeze-glycol, fuel, soot |
Water or other contamination liquids reduce the lubricity
and the wear protection of an oil. Soot increases the viscosity, fuel reduces
the viscosity. The development of an ideal lubrica-tion film is influenced
by those contaminants. |
| oil condition |
oil oxidation, nitration, sul-phation |
Oil oxidation is caused by long term use of the lubricant
without oil change or too high operat-ing temperature. Blow by gases are
the rea-son for nitration and sulphation which increase the acidity level
of the oil. Sludge formation and increased viscosity can be a result. |
