What is the maximum continuous oil temperature in Celsius?

• A. 150C
• B. 155C
• C. 160C
• D. 165C

Answer: (B)

Maintaining oil temperature within limits is essential for proper lubrication. The maximum continuous oil temperature is the highest temperature the oil can stay at without degrading or losing its lubricating properties over an extended period. At 155C, the oil maintains a safe viscosity and resist oxidation and additive depletion long enough for normal operation. Higher temperatures can hasten oil breakdown, reduce lubrication quality, and increase wear, so those higher figures are typically reserved for short-term tolerances rather than sustained operation. A value like 150C would be lower than the true continuous limit, while 160C or 165C would imply the oil could be held up to those temperatures only briefly, not continuously. Hence 155C is the correct continuous limit.
