What is the maximum value in the green oil temperature range?

• A. 155 C
• B. 156 C
• C. 163 C
• D. 150 C

Answer: (A)

Green oil temperature range marks the normal operating window for engine oil temperature. The upper limit of that green arc is the maximum temperature considered normal. Among the given values, 155 C is the highest temperature that still lies within the green range, so it represents the maximum value allowed in normal operation. Temperatures like 156 C or 163 C would exceed the green range and indicate the oil is approaching or in a higher caution/red zone, while 150 C is inside the green range but not at its upper limit.
