How Long Can A Car Go Without Changing Oil?

Oil changes are an essential part of car maintenance. Don’t get caught out with a dry engine!

Now that you know how to change an oil filter and replace the fluids, you might be wondering how long can you go without an oil change?  

While the manufacturer will offer guidelines showing how many miles for an oil change, these aren’t set in stone. In this article, we review how often to get an oil change. 

Before we answer how long can a car go without an oil change, it’s vital that you understand why the oil change is critical. Motor oil is used to lubricate the moving parts of the engine and keep dirt or debris from ruining the mechanical aspects. As the motor oil becomes dirty and contaminated, it is less effective at providing this lubrication. 

The result is a change to the engine temperature and a lack of protection for the moving parts. Both of these problems will lead to premature wear on the motor. Additionally, the oil can no longer remove the dust particles and debris, thereby causing more wear on the vital components.  

As the engine fails to work properly, you could be looking at replacing it sooner than necessary, which can be an expensive repair. Additionally, up until the point that the engine fails, it won’t run the way it was intended. These problems could lead to a lack of performance or acceleration, as well as decreased fuel economy.  

Basically, your car or truck engine requires regular oil changes to ensure it lasts as long as it should, runs the way it was intended, and keeps the moving parts from failing.

How To Check If Your Oil Needs To Be Changed: DIY Guide  

Do you know how many miles between oil changes is considered ideal? To get the answer, you can check the owner’s manual of your vehicle or follow the recommendations from the oil company. However, there are times when your vehicle might need more frequent oil changes. If you notice any of these symptoms, it’s time to change the oil. 

  • Darker color or thicker consistency 
    You can check this with the dipstick. Motor oil should be a light brown, transparent color when it is fresh.
  • Burning oil smell 
    Verify that no oil was spilled on the engine first.
  • Knocking sound from the engine 
    This is an indication that there is a lack of lubrication.
  • Dashboard warning light 
    The sensors in the engine can tell you when something is wrong. 

How Long Can You Go Without An Oil Change? (In Theory) 

How many miles can you go over an oil change and still be okay? There’s no concrete answer to this question, leading you to ask – is it bad to go 1,000 miles over an oil change? If you don’t change the oil at all, the engine won’t be able to perform and will eventually fail.  

Most experts recommend changing conventional oil every 3,000 to 5,000 miles or up to 10,000 miles with synthetic oil. While it probably won’t hurt to go a little over this time frame, the neglect could lead to bigger problems down the road.  

What happens if you go too long without an oil change? The internal parts of the engine can start to rub together, causing wear that is irreparable. Once the damage is done, you won’t be able to fix it with an oil change. That’s why if you are asking, “How often should I change my oil,” we will always recommend following the manufacturer’s guidelines.
