You park your car on a level ground and shut off the engine, wait about 5 or 10 minutes to let the oil drip back down to the oil pan at the bottom, than you check the engine oil level of the oil pan. If the oil level is over the dipstick FULL mark, you have overfilled the oil pan, you can take the drain plug out and let some oil out, and if it is not up to the FULL mark on the dipstick, add some more oil . Do not overfill the engine oil, because the oil level is supposed to be below the front seal and the back seal of the crankshaft, so it won’t create an oil leak. Overfilled engine oil can cre
How to check oil level on a car?

Do not overfill the engine oil, because the oil level is supposed to be below the front seal and the back seal of the crankshaft, so it won’t create an oil leak. Overfilled engine oil can create foaming or bubbling when the counterweights of the crankshaft are slapping on the surface of the oil when rotating, the oil is pumped through all the drilled holes or orifices of the crankshaft and camshaft, push rods. Oil is circulating throughout the entire engine by the engine lubrication system, the oil pump is used to pump oil at a minimum of 40psi to send the oil to go through all the moving parts for lubricating and cooling the engine.
How long should you wait to measure oil?
Engine oil must be measured with the engine off. The length of time it should be off before measuring varies from 5 minutes to about 30, depending on the engine. If you measure and add before that rest/drain period, you will be overfilling the engine, causing foam, poor lubrication, oil light pressure might come on. That oil ends up going through the rings to burn, or pushed back up the dip stick.

What is the yellow cap on an engine?
This small, usually yellow cap with a loop is often labeled "Engine Oil," but even if it is not it is not difficult to find. The dipstick is a long piece of metal that extends down a tube to the oil pan, telling you, based on how high the oil line is, how much oil is in the engine.

Its color is also dependent on mileage. For example, if you are driving an older car 5000 miles a month, your car might burn a quart of oil a month. If the oil looks milky or white you could have a coolant leak and must get the car towed to a mechanic immediately.
