Can snowblower oil freeze? Can snowblower oil freeze?
If you do not use the proper snowblower oil given the weather conditions, then your snowblower oil will begin to freeze. Snowblowers use standard motor oil, and it would take incredibly low temperatures to get it to freeze completely. The recommendation for most snowblowers is to use 5W30 or 5W20 motor oil in order to allow the engine to run smoothly. Check your snowblower's manual for the proper oil weight. If you use a 40 weight oil or something thinner, then the oil will start to turn to sludge in the colder weather and cause damage inside your snowblower engine.
