What would be great is if ford included reference materials that give the consumer an understanding of what the service intervals should be, so they don't need to guess!
I happened to find one.
On the page that says "Oil Change Reminder" it outlines 3 criteria of when you should listen to the oil life indicator, and when you might want to increase your service interval depending on your driving style. Never to exceed 1 year or 10,000 miles.
Go figure!
NORMAL = 7500-10000 miles, which they define as "normal commuting, highway driving, no or moderate loads and towing on flat roads, no extended idling"
Severe = 5000-7500 miles, moderate to heavy load, towing, mountainous or off-road conditions, extended hot or cold operation, extended idling
Extreme = 3000-5000 miles, max load or towing, extreme hot or cold operation
Most people probably fall between Normal and Severe. So 7500 miles or sooner is probably the sweet spot.
