How often do you change the oil on a 2018 Ford Focus?

The recommended oil change interval for a 2018 Ford Focus is every 7,500 miles or 6 months, whichever comes first. However, this may vary depending on your driving conditions and habits, so it’s always best to consult the owner’s manual for specific recommendations for your vehicle.

Not changing the oil in your vehicle at the recommended interval can have several negative consequences. Over time, the oil can become contaminated with dirt and metal particles, which can damage the engine components. Old oil also loses its viscosity, which means it can’t effectively lubricate the engine parts, leading to increased friction and wear. Additionally, not changing the oil can cause a buildup of sludge and other deposits, which can clog oil passages and reduce the engine’s efficiency. Ultimately, not changing the oil at the recommended interval can shorten the life of your engine and potentially lead to costly repairs.
