What is the best way to keep a Ford Focus engine running smoothly?

I have a Ford Focus with 50,000 miles on it and I want to make sure the engine stays in good condition for as long as possible. Any tips or suggestions for maintenance?

Regular oil changes and proper maintenance is key to keeping your Ford Focus engine running smoothly. Make sure to follow your car's maintenance schedule and address any issues immediately.

In addition to regular maintenance, one way to prolong your engine's life is to avoid harsh driving habits. Accelerating and braking aggressively can put extra strain on the engine and wear it out faster.

Another important factor is using high quality fuel and keeping your fuel tank clean. Dirty fuel can damage your engine over time, so make sure to use a reputable gas station and occasionally add fuel system cleaner to your tank.
