For a stock engine car, the oil temperature will reach about 90°C to 105°C when cruising at 100 km/h on the highway. Since the temperature rises even more during circuit driving, be sure to cool the oil when it reaches 130℃.
Above 130°C, the performance and life of the oil will begin to decline rapidly. (Oil performance varies by manufacturer and brand, so please consult your dealer for details.)
If the oil temperature exceeds 140℃, oil pressure will not be normal, so care must be taken not to raise the oil temperature too high. If an oil cooler is installed, it is recommended that the capacity be set so that the oil temperature during circuit driving is between 90℃ and 110℃. For reference, the oil temperature of Class 3 NA engine cars in Super endurance race is stable at around 100℃.
ADVANCE FD and Defi Sports Display F have a warm-up mode that changes to a blue display when the oil temperature is lower than the set temperature. This can be used as a guide for warm-up operation.
