What is the best way to maintain the Ford Transit Custom's engine?

I recently purchased a Ford Transit Custom and I want to make sure I am properly maintaining the engine. What are some essential maintenance tips and schedule for optimal performance and longevity?

Regularly changing the oil and filters is key to keeping your engine running smoothly. I recommend doing this every 5,000 to 7,500 miles depending on your driving habits. Also, make sure to check the oil level frequently and top it off as needed.

In addition to regular oil changes, it's important to follow the recommended maintenance schedule for your specific Ford Transit Custom model. This includes checking and replacing spark plugs, timing belts, and coolant. Refer to your owner's manual for the specific mileage intervals for these tasks.

Don't neglect your air filter either. A dirty air filter can reduce fuel efficiency and cause engine damage. I suggest checking and replacing it every 12 months or 12,000 miles.
