ok, every single car i have ever owned, the oil Dip Stick shows the Full mark when you Fill the oil Pan and Filter, with the Owners manual recommended oil fill.

Issue, i did my first oil change, on the 2010 F150 4.6L motor.
the Manual says, 4.6L = 6.0 Quarts oil.

ok, i drain pan completely, change filter.
Put in 6.0 quarts of oil, Start engine, check for pressure, then leaks,
Turn Engine off. On Level Ground, check oil Dip stick, and it reads 1/2 quart low.
( the oil is in the Middle of Cross-Hatch & Holes, showing 1/2 quart low).

so i add 1/2 quart, (6.5 quarts), and it is on the full mark.

IS THIS A FORD-ism?????
