Re: Oil change
What oil are you using?
What ambient temperature is it?
How is the oil level after 5000 (high or low)?
Are you using a motorcraft filter?
Can you verify that your oil filter cap is OEM?
Also, you may have an injector acting up (ie "stiction", which is oil related) based on a P0284 code that you posted about late last year.
