Overfilling with oil can cause foaming, which turns a slippery lubricant into a sudsy fluid with air bubbles that diminish the lubricating and cooling properties.What happens if oil level is above Max?
When too much oil is added, the level in the oil pan becomes too high. That allows a fast-moving lobed rod called the crankshaft to come into contact with the oil and essentially aerate it. The result is a foamy, frothy substance that cannot properly lubricate the engine.How much oil should be on a dipstick?

In severe cases, insufficient oil flow could result in overheating – not a good thing. Dipsticks are only good if they are used. I suggest that anyone who overfills and admits it happens on occasion due to faulty equipment, does not check his or her work and a dipstick is of no use.Can overfilling oil blown head gasket?

If you're not changing the oil and only are adding oil, you can do so when it's hot without a problem. The cold oil will not harm your hot engine.
