Changing the engine oil in your vehicle is crucial. If, however, you aren't sure why it is so important, read this post to find out what can happen if you neglect this maintenance task.

What Happens When You Don't Change Your Engine Oil

Most professional mechanics would agree that changing the engine oil in your vehicle on a regular basis is one of the (if not, the) most important maintenance task you can follow through to keep your vehicle in top shape for longer. So much so, in fact, that Complex recommends changing your vehicle's oil:
  • if you've driven more than 5,000 miles on it,
  • if the oil is dirty and gritty,
  • if the "oil" sign on the dashboard lights up,
  • if its levels drop,
  • if the engine starts making weird noises,
  • or if it's been so long since the last replacement that you don't even remember the date.
However, if you're left wondering why exactly you should be so diligent with this task, in this post you'll find a few of the consequences of neglecting it.

The Oil Won't Lubricate and Protect

The oil you pour into your vehicle has two very important jobs: to lubricate and protect the moving components in the engine. However, after some time and use, the consistency and the effectiveness of the oil can change due to the extreme conditions it has to endure. For example, the friction reducers and other additives in the oil will begin to fade out, meaning the oil won't be able to perform adequately.

The Oil Will Get Dirty

As mentioned above, one of the signs that you need to get the engine's lubricant changed is if it's dirty. This is because the oil will start to pick up dust, sediments, and other filth, which can change its texture and thickness. As you know, the oil is meant to reduce the friction inside the engine and the wear it can cause. However, dirty oil may actually accelerate the erosion process, as its roughness can increase the amount of friction.

The Engine May Overheat

When your vehicle is on, the engine is running, and when the engine is running, its components are moving. Whenever the engine's parts move, they rub against each other, which results in excessive friction and extreme temperatures. The oil helps reduce that friction, while the coolant regulates the vehicle's temperature. However, if you don't do a good job of changing the oil, the friction will increase and the engine may overheat.

Your Engine Will Get Louder

Have you ever been at a stop light and had a really loud car stop beside you and wonder how they could stand such a sound? If something like this has happened to you, then you know that having a loud engine isn't an ideal situation. Not only can it distract you and disturb the people around you, but it can be a sign that something is very wrong with your engine. Regular oil replacements will probably take care of that.

The Engine's Components Will Suffer

As mentioned time and time again in this post, one of the main reasons why you should use synthetic oil for your engine is to protect its moving components from the incessant rubbing that goes on between them when your vehicle is running. The oil coats these components, helps them endure the harsh conditions, and prevents premature damage. Without proper replacements, however, the engine's components will surely suffer.

Your Vehicle's Life Expectancy Will Decrease

The engine is probably the most important part of your vehicle, so if you don't care for it properly and replace its oil whenever needed, it is safe to say that your vehicle's life expectancy will decrease significantly. As the components in your engine start breaking down due to a lack of protection and lubrication, the vehicle's performance will suffer as well, until the engine is rendered completely useless.

Your Wallet May Take a Hit

Last but not least, you should consider your personal economy. You may think that purchasing new oil for your vehicle on a regular basis can be a financial burden. However, the price of not complying with this maintenance task may be much greater, since fixing or replacing an engine altogether can be a lot more expensive, time-consuming, and stressful.
