Can You Put Oil into a Hot Car Engine?
The Answer is Yes, But…
Yes, you can put oil into a hot car engine, but it is not recommended. When you add oil to a hot engine, the oil can thin out and lose its viscosity, which can lead to decreased engine protection. In addition, adding oil to a hot engine can cause the oil to foam, which can also lead to decreased engine protection.
If you must add oil to a hot engine, do so slowly and carefully. Be sure to check the oil level before and after adding oil to ensure that you are not overfilling the engine.
Why is it Not Recommended to Add Oil to a Hot Engine?
There are a few reasons why it is not recommended to add oil to a hot engine:
- The oil can thin out and lose its viscosity. When oil is heated, it can thin out and lose its viscosity, which can lead to decreased engine protection. This is because the oil will not be able to create a thick enough film on the engine’s metal surfaces, which can lead to increased wear and tear.
- The oil can foam. When oil is added to a hot engine, it can cause the oil to foam. This is because the air in the oil will expand when it is heated, which can cause the oil to become frothy. Foamy oil is less effective at lubricating the engine, which can lead to increased wear and tear.
- The oil can expand. When oil is heated, it will expand. This can cause the oil level in the engine to rise, which can lead to overfilling. Overfilling the engine with oil can cause a number of problems, including increased oil consumption, decreased engine performance, and even engine damage.
When Should You Add Oil to Your Car Engine?
The best time to add oil to your car engine is when the engine is cool. This will allow the oil to circulate properly and reach all of the engine’s components. Be sure to check the oil level regularly, and add oil as needed to keep the oil level between the “full” and “add” marks on the dipstick.
What Type of Oil Should You Use?
When adding oil to your car engine, be sure to use the type of oil that is specified in your owner’s manual. Using the wrong type of oil can damage your engine.
Conclusion
So, can you put oil into a hot car engine? Yes, but it is not recommended. If you must add oil to a hot engine, do so slowly and carefully, and be sure to check the oil level before and after adding oil.
