About 12 hours. This morning I went on the highway. I just checked my oil now. Oil is back to no rmal. I wonder what substance I burned off.How long did the car sit before checking it? Oil certainly cannot "expand" on its own, but the longer the car sits, more oil has time to drain into the pan from the engine.
Like I said, I only check it cold. Wiped it too. The oil level seemed to level after I drove on the highway this morning and let the car sit for 12 hours. I wonder if I burned off moisture or fuel?Your oil level will be higher when the oil is at operating temperature vs when it is cold. Oil expands like any other liquid when hot. Always check it when cold.
Also, make sure you are checking it properly. Pull the dipstick, wipe it, put it all the way back in then pull it out and check it.
