Drive farther between oil changes.
Has anyone sent their Motocraft syn blend in for testing? If not I might send mine in at the next oil change and go from there on how long to go between changes. I'm currently changing at 3000 miles on my 05-5.4 3V.

Most filters are only guaranteed for 3 months so I think this new interval will only help those of us who drive 2000 miles a month or more.

We've fired people for trying to pad their paychecks as you describe.
