This practice of leaving your vehicle running after changing the oil has been passed down through generations – but is it really necessary?

In this article, we'll investigate whether or not letting your car run after adding oil is beneficial and why.


What Happens When You Put Oil in Your Car?

Before we dive into the topic at hand, let's first discuss what happens when you pour oil in your car.

Oil is essential for proper engine functioning because it helps lubricate moving parts and prevents friction.

When changing your car's oil, you are replacing used oil with fresh, clean fluid – keeping the engine running smoothly while avoiding damage caused by dirty old oil.

Allowing your engine to run after adding oil can actually do more harm than good by damaging it rather than helping it.


Why Not Let Your Car Run After Adding Oil?

There are several reasons why it's best not to let your car run after adding oil.

First and foremost, running the engine when not needed can put undue strain on its components, shortening its lifespan and increasing chances for failure sooner.

Finally, allowing your vehicle to idle after adding oil leads to carbon deposits buildup within the engine which causes it to run less efficiently and emit harmful emissions into the atmosphere.


When Should You Check Your Oil Level?

Though you don't need to let your car run after adding oil, it is still essential to check its level regularly.

Doing so can help identify any potential issues with the engine before they become major ones.

We suggest checking the oil level at least once a month or more often if you hear or smell unusual noises coming from within the engine compartment.
