Car consumes 3/4 Quart of Oil for first 1000 miles and basically stays at a 1/4 for another 4000 miles?

I have been noticing this for sometime, no visible leaks underneath, no drips either and I have been looking and checking pretty routinely, what would cause after a oil change for the car to consume 3/4 of a quart for the first 1000 miles and then basically stay at a 1.4 for another 4000 miles? Vehicle is 2006 Ford Taurus SE OHV 3.0

Added (1). note. When I say a quarter. I'm talking about the 1/4 line (amount) on the dipstick from full to re-fill

That 3/4 might be the oil that goes into the oil filter and stays there after an oil change and engine start. There's no other explanation as to why you use 3/4 qt in 1000 miles and virtually nothing after that. The oil capacity of your car is 4.5 qts - without an oil filter change.

It probably "consumes" that extra oil in the first three seconds when you fill the new filter.
