The oil level measurement is unaffected by the temperature of the oil. However, whether the engine oil is hot or cold, a tiny expansion might occur.
Do you check the oil when the engine is hot or cold?
We recommend checking the oil level either before turning on the engine or 5 to 10 minutes after shutting down so you can have all the oil in the oil pan to get an accurate measurement.
Does oil read high when engine is hot?
Temperature of engine shouldn’t make any difference on oil level. If you check it hot, such as at a fuel stop, let it sit off for five minutes before you check it to allow the oil to drain back down to the oil pan.
What happens if you overfill 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.

Does engine oil get thicker or thinner when hot?
Motor oil gets thinner as it’s heated, but to prevent it from getting too thin at higher temperatures, additives (viscosity modifiers) are used so that it behaves like a thicker grade oil at higher temps.
Is oil level lower when cold?
When outside temperatures are colder, oil level readings will be inaccurate. There are ways to get checking oil when it is cold done that will get accurate results.

Should I add oil if low?
If dipstick tells you that your oil level is low, you should top up your engine oil as soon as possible. The first step in doing this is to make sure you add the right oil. Your car’s user manual can help with this, or you can also use our quick and easy Oil Finder tool.
What happens if you drive around with low oil?

Can you mix old and new engine oil?
When you mix new and old oil, the new oil becomes “watered down” with the lack of interfacial tension and strains to do its’ job. Be sure to have your oil changed as soon as possible.
How often should you refill your oil?
It used to be normal to change the oil every 3,000 miles, but with modern lubricants most engines today have recommended oil change intervals of 5,000 to 7,500 miles. Moreover, if your car’s engine requires full-synthetic motor oil, it might go as far as 15,000 miles between services!
What color should oil be on dipstick?
