The 3.0L OHV engine takes between 4.5 and 5 qts. I have found it varies a little. THe 3.0L DOHC engine takes 5qts, possibly 5.5qts.
Add 4 quarts, run engine for about 30 seconds and top off to the full mark with the dipstick as a gauge.
1 qt of primary oil
Right at 6 quarts with a filter change.
On a completely empty system that has been flush out, it will hold 10 ounces of oil and 1 pound and 14 ounces of R134a freon..........
5.5 Quarts with filter change.
You Dont Grease It Up enough
