HOTLOP stands for which pair of engine conditions?

• A. High Oil Temperature and Low Oil Pressure
• B. High Oil Temperature and High Oil Pressure
• C. Hot Oil Pressure
• D. High Output Power Load

Answer: (A)

At the heart of this question is how engine condition acronyms signal two related issues in the oil system. HOTLOP means HOT = High Oil Temperature and LOP = Low Oil Pressure. Seeing both together indicates a dangerous lubrication situation: oil is too hot (reducing viscosity and effectiveness) while pressure is too low (not getting enough oil to bearings). This combination is the only one that describes both conditions at once, making it the correct interpretation. The other options don’t fit because they either describe temperature without a low pressure condition, mix in a different meaning (like a generic “Hot Oil Pressure” phrase), or refer to something unrelated like load or output power.
