During snow clearing of a large parking lot, the loader operator notices excessive fuel consumption and reduced power from the machine. The ambient temperature is -25°C. What is a likely cause related to winter operations?

Question: During snow clearing of a large parking lot, the loader operator notices excessive fuel consumption and reduced power from the machine. The ambient temperature is -25°C. What is a likely cause related to winter operations?

Answer options:

• Overheating of the hydraulic system due to extreme cold.
• Blocked air filter restricting engine airflow. ✅ Incorrect engine oil viscosity for cold temperatures.
• Improperly inflated tires reducing traction.

Correct answer: Incorrect engine oil viscosity for cold temperatures.

Explanation: Using an engine oil with an inappropriate viscosity for frigid temperatures (e.g., too thick) can lead to increased drag on engine components, resulting in reduced power and higher fuel consumption. Cold temperatures generally improve heat dissipation, making overheating less likely.
