How often should the oil be changed on a Ford Transit Custom?

I recently purchased a Ford Transit Custom and I'm wondering how often the oil should be changed. I've heard varying opinions on this and I'm unsure of what the best course of action is. Any advice would be greatly appreciated.

It's recommended to change the oil every 5,000 miles or every 6 months, whichever comes first. This ensures that your engine stays running smoothly and prolongs the life of your vehicle.

I personally change my oil every 3,000 miles. It may seem excessive, but it's better to be safe than sorry. Plus, it's cheaper to change the oil more frequently than to deal with potential engine problems down the line.

Some mechanics say you can go up to 10,000 miles before changing the oil, but I wouldn't push it that far. Stick to the manufacturer's recommended interval and you'll be fine.
