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.
The practice of topping off your oil is essentially just like it sounds — you’re adding fresh oil on top of existing oil. However, the trouble with mixing new and old oil is the new oil can become contaminated in the process or allow impurities to continue building in your engine.
Whether you’re simply topping off on oil or if you’re adding several quarts after an oil change, you should ensure that the engine is shut off during the process. If you’re topping off on oil, it’s also recommended to give the engine several minutes to cool off before adding oil so you don’t burn yourself.
Is it OK to add oil when engine is hot?

How much oil should I add to my car?
Typically, engines need five to eight quarts of oil. However, the size of your engine can impact how much oil is required. For example, a 4-cylinder oil engine may require around five quarts of oil, whereas a 6-cylinder oil needs six quarts. Usually, the smaller the engine is, the less oil you’ll need for your vehicle.
If the oil is below the minimum mark, you need to add oil. (Use the oil type recommended in the owner’s manual, adding just no more than half a quart at a time. Let the car sit, then check again.) Pay close attention to the old oil’s color.

How often should I top up my oil?

What causes a car to lose oil?
(1) It may have an oil leak or (2) it could be burning oil during the ignition cycle. One common problem is if the cylinder walls are allowing oil to leak up from the bottom of the engine, past the piston and into the combustion chamber. So when the fuel ignites, the oil does as well, and then expels it out as exhaust.
