Quick Answer
No, do not keep the engine running overnight for heat. This can cause more harm than good, wasting fuel, and potentially leading to engine damage or carbon monoxide poisoning. It's better to use alternative heat sources.
Dangers of Idling Engines
When stranded in cold weather, it’s tempting to keep the engine running for heat, but this can be a bad idea. Idling an engine for extended periods can cause significant wear and tear on the engine, potentially leading to costly repairs. For example, idling the engine for 6 hours at -20°C can reduce the engine’s lifespan by up to 40%.
Alternative Heat Sources
In place of running the engine, you can use alternative heat sources such as a portable heater, hand warmers, or a sleeping bag rated for sub-zero temperatures. These options are generally safer and more fuel-efficient than idling the engine. For example, a portable propane heater can provide 10,000 BTU of heat for up to 9 hours on a 20-pound propane tank.
Safety Precautions
If you do decide to run the engine, make sure to follow proper safety precautions to avoid carbon monoxide poisoning. Open a window or door to provide adequate ventilation, and ensure the exhaust pipe is not blocked by snow or ice. It’s also essential to check the engine oil and fuel levels regularly to avoid engine damage.
