Is it better to add oil to hot or cold engine?
Most oil experts say it’s better to drain the oil when it’s hot instead of when it’s cold, for several reasons: Oil viscosity is thinner when it’s hot, so it drains more quickly and completely out of the engine than when it’s cold.
Why do you heat oil before adding?
Heat causes proteins to fold in on themselves, or even to break down and form all new compounds. Once in their folded or rearranged form, they no longer stick.

What happens if you overfill your oil?
Too much oil in the engine can also cause the pressure on the crankshaft to increase, causing oil to enter the exhaust pipe from the crankshaft into the combustion chamber, blocking the combustion chamber hole with oil and eventually clogging the engine. Wet spark plug; excess oil will also flood the spark plug well.
What happens if you overfill oil by 1 quart?
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 is too much oil on a dipstick?
If the excess oil is sitting 1-2 millimeters above the fill line, there is no cause for concern. However, if there is more than a quart of excess oil, you should remove it as soon as possible to avoid costly damages.
What happens if I overfill my oil by half a quart?
An extra half a quart of oil in your crankcase is not going to do any harm to the engine. If the crankcase were seriously overfilled — say, more than a quart — then the spinning crankshaft could come into contact with the liquid oil, and churn it up. Then you’d get oil foam.

Why does my dipstick show too much oil?
3 – What If the Oil Level is Too High? In certain cases, the oil level may have risen since the last time you checked or there is too much oil on the dipstick. This could be due to condensed water (from combustion), condensed fuel or a coolant leak – all are causes for concern.
Should oil be at the top of the dipstick?
There will be two marks on the dipstick to show the optimum level that your oil should be at. Your oil level should be somewhere between the two. If your oil level is below the bottom line, or if there isn’t any oil on the dipstick at all, you should immediately top up your engine oil.
Should you read the oil dipstick the first time you pull it out?
4. Wipe the dipstick (from the handle to the tip) with a clean rag or paper towel. The reading you get from pulling the dipstick out the first time isn’t accurate because the motor oil can splash around or wick upward on the dipstick.
What happens if you don’t fill oil all the way?
If you don’t maintain the proper oil level by checking it regularly and adding oil when needed, the oil level drops, and some parts of the engine won’t receive the lubrication they need. This results in premature engine wear, and, over time, it can lead to expensive repairs.
