Do I Need to Let My Car Cool down before Adding Oil?

If you’re like most people, you probably think that it’s a good idea to let your car cool down before adding oil. After all, oil is used to lubricate and protect engine parts, so it makes sense that it would be better for the engine if the oil were cooler. However, there’s actually no need to wait for your car to cool down before adding oil.

In fact, it’s often best to add oil when the engine is still warm. Here’s why: When an engine is cold, the oil is thicker and doesn’t flow as well.

This can make it difficult for the oil to reach all of the engine’s moving parts. As a result, those parts may not be properly lubricated and could wear out more quickly. Adding oil when the engine is already warm helps ensure that the new oil will flow easily and reach all of the engine’s moving parts.

This provides optimal lubrication and protection for your engine.

If your car’s engine is low on oil, you may be tempted to just add more oil to it. However, it’s important to know that adding oil to a hot engine can actually do more harm than good. The heat from the engine can cause the oil to break down and become less effective.

This can lead to even more problems down the road, so it’s best to avoid adding oil to a hot engine altogether.
