Oil temperature between 140°C and 155°C may be operated for up to how long?

Explanation:
Oil in the 140–155°C range is considered a high-thermal condition, so the operating limits allow only a limited duration to protect the oil and lubrication system. You may operate up to 45 minutes in this band; longer operation increases the risk of oil oxidation, varnish buildup, and accelerated wear of bearings and gears. If more time is needed, reduce load or power and allow the oil to cool back toward a lower temperature before continuing.
