Let me clue you in on something I didn't know but do now and hopefully will help others.
I had an isuzu pickup truck 4cly. I did an oil change one night, ran and check, everything ok. A day or two later, went back out, in the morning, open'd the hood, pull the stick and I was a quart low!. WOW, never seen that before but hey, dip stick can't lie, so I put another quart in. Later that day, checked it again to make sure I wasn't losing to fast, I then was a quart high!.
What I learned was that when checking the oil with a dip stick, to first pull out the stick(even if it's been sitting all night), clean it off and reinsert. The isuzu has a rubber seal around the dip stick and will great an air block not allowing the oil to level out on the stick at the end of the day. Kinda like putting your finger over a straw and inserting it into a glass of water, water cannot go up the straw. First time I'd ever seen that.
