How Long to Let Engine Cool before Adding Oil

If you’ve just driven your car, you may be wondering how long to let the engine cool before adding oil. The answer can vary depending on a few factors, but in general, it’s best to wait at least 30 minutes before topping off your oil level.There are a few reasons for this.

First, when your engine is hot, the oil is thinner and will flow more easily. This means that if you add cold oil to a hot engine, it could cause sludge or other deposits to form. Second, if you open the hood while the engine is still hot, steam or other hot vapors could escape and cause burns.

Finally, it’s simply easier to check the oil level when the engine is cool so that you can avoid overfilling it.Of course, if you’re low on oil and need to add some right away, don’t worry too much about waiting for the engine to cool down first. Just be sure to check the level again after the engine has had a chance to cool completely so that you can add more if necessary.

Easy!However, if you’re topping up an empty or nearly-empty engine, things are a bit more complicated. You’ll need to locate the drain plug (usually at the bottom of the engine) and open it up to let all of the old oil drain out.
