Why Engine Oil is Important
Engine oil plays a vital role in the functioning of your vehicle’s engine. It lubricates the moving parts, preventing friction and wear, and helps to cool the engine by carrying heat away from the combustion chamber. Regular oil changes are essential to maintain the health of your engine and prevent damage from dirty or degraded oil.
Types of Engine Oil
There are several types of engine oil available, each with its own unique characteristics and benefits. Some of the most common types of engine oil include:
- Conventional oil: This is the most common type of engine oil and is suitable for most passenger vehicles.
- Synthetic oil: This type of oil is more expensive than conventional oil but provides better lubrication and protection in extreme temperatures.
- High mileage oil: This type of oil is designed for vehicles with high mileage and contains additives that help to condition seals and gaskets.
- Full synthetic oil: This type of oil is a blend of synthetic and conventional oil and offers a balance of performance and price.
