Eh, it certainly won't hurt anything, other than your bank account. I guess it depends how paranoid you are. On my '07, the specified normal interval is 8,000 Km, but now even Ford has extended that, for later model years. They haven't changed the engine at all, it's just based on their reliability data of more than a decade.
I generally don't let mine get over 10,000, but I also use synthetic and change the filter every time, so I think I'm pretty safe. Maybe in the long run it will mean the difference between getting 300,000 km instead of 400,000 km out of the engine -- but the odds are something besides the engine will kill my truck long before that becomes a concern. And that's assuming I still own the truck at that mileage.
Just my opinion, but I think 5,000 km is waaaay over-kill for modern engines. High mileage older vehicles, maybe not.
If Princess Auto were a real girl, I'd ask her to marry me.
