Balap (Racing)

Balap Grand Prix menggunakan mesin berkinerja tinggi mutakhir yang beroperasi pada RPM dan suhu ekstrem. Untuk menjaga mesin yang sangat berharga tetap beroperasi dan kompetitif, diperlukan tim mekanik yang memperhatikan kondisi mesin dan pelumas dengan cermat. Untuk mendukung hal ini, pemantauan kondisi mesin berdasarkan analisis oli telah menjadi teknik yang dipraktikkan secara luas oleh tim balap Formula Satu.

Wear

Particle composition - it is often important to understand the elemental composition of particles in order to find out where they came from. Optical Emission Spectroscopy gives the user elemental information for up to 32 elements, from Li to Ce (varies with application).

Chemistry

Total Base Number (TBN) - TBN measures the amount of active additive left in a sample of oil. The TBN is useful for people who want to extend their oil usage far beyond the normal range. The TBN of a used oil can aid the user in determining how much reserve additive the oil has left to neutralize acids. The lower the TBN reading, the less active additive the oil has left.

Viscosity - The main function of lubrication oil is to create and maintain a lubrication film between two moving metal surfaces. Insuring the viscosity is within recommended ranges is one of the most important tests one can run on lube oil.

Oxidation, Nitration, Sulfation - Lubricating oil at elevated temperatures can react with oxygen and nitrogen in the atmosphere, as well as sulfur in fuel, to form undesirable by-products that can affect the oil's viscosity and lead to corrosion or damage of equipment.

Contamination

Glycol - Glycol is found in engine coolant. If glycol is found in engine oil it typically indicates there is a leak in the engine that allows coolant into the oil system. Glycol reduces the oil's protective properties and can cause catastrophic damage to the engine components.
