Description

A must for road use when an oil cooler is fitted In the past, fitting an oil cooler was mandatory once an engine had been even slightly uprated. The main reason for this was the quality of motor oils available at that time. If the oil temperatures regularly exceeded a specific point(100c) engine failure was almost guaranteed. Modern motor oils are generally of a much higher quality, especially the ‘brand names’, and have far superior high temperature tolerance than those of 10 or 15 years ago. Fully synthetic oils have extremely high heat tolerance. Use of any of these oils makes an oil cooler less of a necessity where engine outputs don’t exceed about 90 horsepower. It is as bad to run the oil temperature too cool as it is to let it get too hot. The ideal operating range is 200 to 230 degrees F (sump temp). At these temperatures the oil is working efficiently to produce the best power, economy and release of combustion by-products. If the oil is too cool, these by-products are absorbed into the oil, requiring more frequent changes to avoid bearing and bore damage. It is worth noting that keeping the oil at the correct temperature helps cool the engine
