The oil will drain no problem…
Put in 6 qts…. Then check the oil on level ground after waiting 15-20 minutes for the oil to settle…
If you can… replace to used oil back into the oil containers and try to measure how much you took out….
Also… I like to check the level stone cold the next day… that is the best way to check your oil level….I usually get the oil between the max full hole and the twist… that is how my Bronco came…. Roughly around 6.5 quarts (depending how much you have drained prior)…
6 quarts should be right at the max fill hole… 7 the oil will be way up in the twist or past the twist…. Stone cold past the twist is too much oil. IMO
I too own the fancy revised dip stick … but use the original…
