Car Engine Oil:  Due to cold in winter, the engine oil thickens, which causes trouble in starting the car engine. Here are some measures that can prevent engine oil from freezing and help your car run smoothly in winter:

1. Choose the right grade of engine oil:

Use thinner oil for winter. Every engine oil has its grade written on the package, such as "5W-30" or "10W-40". Thinner oils like 5W-30 work better in cold weather because they flow easily and do not freeze in the cold.

2. Keep the car covered:

To protect the car from cold, use a cover at night so that the engine is less affected by the cold. If possible, keep the car in the garage so that the engine and oil remain warm.

3. Use a block heater:

Many people use a block heater during the winter season. It is installed in the engine block, which helps in keeping the engine warm in the cold. It is installed at night so that the engine oil does not freeze in the morning.

4. Use oil heater or engine heater:

Some people also use engine or oil heaters, which are helpful in keeping the engine and oil warm. These heaters maintain the temperature of the engine and help in starting the engine in cold weather.

5. Drive the car regularly:

Even if the car is not in use, drive it for some time regularly. This keeps the engine warm and reduces the thickness of the oil.

6. Use winter grade oil available in the market:

In winter, special winter grade engine oils are available which remain liquid even in low temperatures. You can use these.

7. Take care of the battery:

Battery capacity also decreases in cold weather, so keep checking it from time to time. A healthy battery starts the engine faster, which is helpful in cold weather.
