For cold climates:
Nissan QR25DE says ten minutes after shut down, oil is hot then. I use this as reference but never top up, always on luke warm reading winter, completely cold summer.
In extreme sub zero weather, oil can contract and show lower reading, topping up can overfill if your fanatical about being right on full mark like I was once.
Hot oil expands some too, too hot oil check may throw one off too. I figure Nissan may want the oil checked 10 minutes later to allow for that expansion on their dipstick full mark setting? I now shoot for about 1/16-1/8" inch lower on full mark on warm (not hot oil) hours later after shutdown to insure no overfill.
My Cummins can sit 5 days, I have checked oil cold sub zero, then plug in heat pad on pan few hours, oil temp then little below operating temp, oil level can then climb up 3/16-1/4 inch from previous cold check based on 12 litre sump.
In winter I like to check my Nissan/Cummins oil level few hours after shut down, lots time oil to drain down hot/warm but oil luke warm room temp on check for accuarate reading. I live in extreme climate.
For those lucky ones in southern U.S. the cold climate factor does not apply to your oil checks. easy cold checks for level there like our summers up here, not winter.
