The best way I have found to check oil is to run the engine anywhere from 5 seconds to operating temperature (I reccomend the latter) and then turn the vehicle off, let it sit a couple second and check the oil. You want all the oil in the vehicle to fill up the gallies, passageways, lines, and pump as it would be under operating conditions to get the most accurate reading. (Much like the way you want to shift into all the gears and back to park when checking transmission fluid)
Now something I haven't seen mentioned when you guys check your dipstick is that you are following these tips:
-Don't hold the pointing down, always horizontal
-Turn it over slowly, you want to see the most consistent streak of oil on the dipstick, meaning no little empty spots, nice consistent coating.
-Oil expands when heated, take this into consideration when checking your vehicle hot or cold.
-Wiping the dipstick and then reinserting it a couple times helps.
Every vehicle splashes oil and the dipstick gets coated in oil, its just how it is... if it didn't happen then the oil wouldn't have a purpose.
