If the temperature is between -26 and -40 degrees, how long should you crank the engine?

When the temperature falls between -26 and -40 degrees Fahrenheit, the recommendation for cranking the engine is to limit the duration to no more than 120 seconds. This is primarily for the preservation of the battery and the engine. Extended cranking in extremely cold temperatures can drain the battery significantly and cause unnecessary wear on engine components.

At such low temperatures, engine oil may thicken, making it more difficult for the engine to turn over. Limiting crank time to a maximum of two minutes allows for sufficient attempts to start the engine while reducing risks associated with overheating the starter motor and creating electrical issues. Therefore, 120 seconds strikes a balance between giving the engine a chance to start and minimizing potential damage or battery drain.
