What Type of Oil Should I Use?

type of oil

Changing oil in your car is necessary for engine reliability, longevity, and performance. There are four main types of oil: regular, synthetic, synthetic blend, and high-mileage. The type of oil you choose depends on the make, model, and engine of your car. Refer to your car owner's manual to see what type of oil is required. Most cars take regular or synthetic oil. Synthetic blend oil is generally required for heavy duty trucks with towing capacity, while high-mileage oil like Castrol Edge High Mileage is often recommended for cars with over 75,000 miles to improve performance in older engines.

Some cars can run on either regular or synthetic oil. Car owners may choose to use synthetic oil, even if it’s optional, to improve overall engine performance. Synthetic oil, specifically Castrol EDGE, can extend the intervals between oil changes since it can tolerate higher engine performance better than regular oil. If you have a hard time keeping to your oil change schedule, you may want to consider switching to synthetic. If your car specifies conventional oil, choose Castrol GTX to protect against sludge buildups.

Owners of cars that can take either type of oil may switch between regular and synthetic oil and even mix types of oil without causing harm to the car, but always check the owner's manual and consult with a qualified technician before making any changes.
