The oil in your car's engine is most important -- more important than gasoline, water, coolant, transmission or brake fluid. Why? Because the engine oil:
- Lubricates the different parts of the engine
- Reduces heat
- Neutralizes acid
- Absorbs unwanted dust and water inside the engine
Over time, the heat of the engine breaks down the oil and the oil filter can't extract any more deposits. If the oil level is low or the oil is too dirty, your engine can be seriously damaged.
