I wouldn't think an original dipstick would be mismarked, the manufacturer should know how high the oil level should be. Tilting the engine shouldn't make a difference if the tilt is within the manufacturer's tolerance unless the dipstick is at one end or the other, not in the middle.

If you remove the old oil by sucking, rather than draining, you have to realize that you won't get it all out so rather than adding "X" quarts of oil, it's best to add less, check the dipstick, and bring the level up to where it's supposed to be.

Overfilling can cause problems so "more" is not better in this case.
