Curious, to the new owners. My '02 5.4 has 100k spark plug intervals. Is that the case with the 2015 motors? I'm assuming oil change intervals are still 5k also. Thanks. And if there's a thread on this already, sorry for the double post.

Unless something has changed the direct injected ecoboost is notoriously hard on plugs - my '11 was misfiring and throwing codes at 60k due to bad plugs (not covered under warranty) so I expected mileage may vary by engine.

Ford utilizes an oil life monitoring system that is based on usage, seems to run around 8k-10k between intervals for me. I'm sure many here will say to ignore this and change based on old school mileage intervals. I say nonsense to that notion, new technology needs to be embraced and Ford wouldn't risk their reputation and service income with detrimental oil change recommendations.

That said, I use full synthetic oil for a little extra assurance. Doesn't save any money but I appreciate the convenience of fewer oil changes!

 

8-10k is pretty impressive. Thanks.
