What color indicates engine oil pressure and temperature indications in the caution range?

• A. Green
• B. Red
• C. Blue
• D. Amber

Answer: (D)

Color coding on engine oil pressure and temperature indicators quickly tells you how urgent the reading is. Green means everything is within the normal operating range. Red signals a warning or danger that needs immediate action. Amber is used for the caution range: the reading is outside the normal band but not yet in the danger zone, so you should monitor closely and follow the abnormal or caution procedures. For engine oil, an amber indication means you should consider checking the oil system and be prepared to act if the condition worsens. Blue isn’t used to denote the caution range in this context; it typically indicates a different status or condition, so it doesn’t apply here.
