Best way to check oil is when you service fuel, and it can be tough to get an accurate reading with fresh oil. Most gas station pads are level, so this is a good time to do it. First thing to do is open the hood, pull the dipstick, wipe it down, and lay it in a convenient place.

The several minutes is takes to fuel will allow oil in the dipstick tube to drain down, which will prevent a false reading. So after fueling insert and remove the dipstick and you should have a clear reading.
