What type of oil should be used?

Changing the oil in your vehicle is essential for engine reliability, durability and performance. There are four main types of oil: regular, synthetic, semi-synthetic, and high mileage. The type of oil you choose depends on the make, model, and engine of your vehicle. Consult your vehicle owner's manual for the type of oil required. Most cars use regular or synthetic oil. Semi-synthetic oil is typically required for heavy duty traction vehicles, while Mobil 1 High Mileage full synthetic oil is often recommended for vehicles over 75,000 miles to improve older engine performance.

Some vehicles can run on both conventional and synthetic oils. Car owners can use synthetic oil, even if it's optional, to improve overall engine performance. Synthetic oils, especially Mobil 1 Extended Performance, can extend drain intervals because they tolerate higher engine performance better than conventional oils. If you find it difficult to keep up with your oil change schedule, you may want to consider switching to synthetic oil.

Car owners who can work with any type of oil can switch between conventional and synthetic oil and even mix oil types without harming the car, but always check the owner's manual and consult a qualified technician before making any changes.
