Can You Put Oil in a Hot Car Engine?

It’s a common misconception that you can add oil to a hot engine. However, this is not advisable and can actually be harmful to your vehicle’s engine.

When to Check and Add Engine Oil

1. Park your vehicle on a level surface.
2. Turn off the engine and allow it to cool down for at least 30 minutes.
3. Open the hood and locate the oil dipstick. The dipstick is usually located near the front of the engine.
4. Pull out the dipstick and wipe it clean with a rag.
5. Reinsert the dipstick into the engine and pull it out again.
6. Check the oil level on the dipstick. The oil level should be between the “min” and “max” marks on the dipstick.

If the oil level is low, you will need to add oil. Use the type of oil that is recommended in your vehicle’s owner’s manual. Add oil slowly and in small increments. Check the oil level frequently as you add oil to avoid overfilling the engine.
