The term oil cooler and oil cooling became very popular in India after launching the Pulsar series 200 (discontinued) and 220 F from Bajaj motors. Oil cooling as we know from the name itself is cooling of engine oil by help of a special component called an oil cooler. Generally an engine oil will loose its viscosity if temperatures are very high than its specified heat range. As a result it may not be able to lubricate the mechanical components properly as specified. To overcome this problem and to provide better cooling especially for air cooled high performance engines oil coolers are generally used.
