- Use a block heater. A block heater is a device that plugs into the vehicle's electrical outlet and helps to keep the engine warm. This can be especially useful in very cold climates.
- Use a synthetic oil. Synthetic oils have a lower freezing point than conventional oils, so they are less likely to freeze in cold weather.
- Add an oil additive. There are a number of oil additives that can help to lower the freezing point of oil. However, be sure to read the product label carefully before adding any additives to the oil.
- Drive the vehicle regularly. This will help to keep the engine warm and prevent the oil from freezing.
