More so, while it is not a problem to add oil to a hot engine, there are tips you should know to avoid getting injured; remember, you’re dealing with a hot engine! This article explains everything you need to know about adding oil to a hot engine.

When Is Best To Put Oil In a Car?

Frankly speaking, it is best to add oil when the car is a bit warm; that way, the oil will flow freely and quickly into the respective parts of the engine.

But if you want to check your car’s engine oil level, it is advisable to do that when the engine is cold or warm, so you can get an accurate reading – oil expands when heated up. In other words, you can put oil in a car at any time.

When your car’s engine starts running short of oil, you’d be notified by the illumination of the oil check icon.

Yes, you can put oil in a hot engine – whether the engine has been running for several hours or just a few minutes. Adding oil to a hot engine would not cause any harm whatsoever; the attention should be on your safety – don’t let any part of your body come in contact with the hot engine.

To be on the safe side, it is advisable to wait for a few minutes – maybe 5 to 10 minutes or more – before proceeding with topping the oil in your car’s engine. Well, this is just to be on the safe side; if you can trust yourself to be more careful, you can add oil to your car’s engine almost immediately as you get out of the car.

Basically, you should always have a quart of oil in your trunk for emergency oil top-up situations. But if you don’t, then you’d have to buy, which may waste you some time – so the engine would be a bit cooler when you finally return from the oil store.
