It’s always an unsettling sight when something lights up your Chevrolet. The oil lights are one of those things that can be a little more than disconcerting, and just like the low tire light, it’s not always clear what you should do.

In this blog post, we’ll explain why your car has an oil service light, what it does, and what you should do when it comes on so you get the most out of your Chevrolet. Keep reading to learn more!

What Happens When The Oil Service Light Comes On?

The oil service light in your Chevrolet is made up of two parts. There’s a sensor in your vehicle that monitors how much pressure is being applied by the engine. There’s also a sensor that detects how much oil the car has. If the pressure or oil level drops too low or gets too high, your vehicle tells you there is an issue by lighting up this warning light.

When it comes on, there are three main issues at play: either you need to change your oil, the oil sensor is faulty, or there’s an issue with your engine. It’s important to note that this light can come on without warning if there’s an issue with your engine. You could be driving your vehicle one minute and then suddenly find you’ve completely lost power to your engine.

If the problem is with the sensors, then they’ll need to be replaced. For example, you might find it strange that you’ve just changed your oil a few weeks ago, and the light still comes on. But that’s because if there’s a faulty sensor, it’ll get some false readings.

The oil service light usually comes on when your engine oil is less than 20% of its life. That doesn’t mean it’s time to get the oil changed straight away, but you should watch how often you need to top up your oil to maintain that threshold. Beware of waiting too long, though, as some cars will need their oil changed every few months depending on the engine type and miles traveled.

If none of these reasons applies to you, further investigation will be required. Contact a certified mechanic to determine the root of the issue.

What Does An Oil Change Entail?

Most manufacturers recommend that you change your oil every 5,000-10,000 miles (8,000 kilometers). If this light comes on, then it may be time to get your oil changed so you can reset the service light. Oil changes are pretty cheap at most service stations, including Sanger Chevrolet Buick GMC.

What can you do if an oil change isn’t in the cards right now because of financial constraints or other reasons? Well, you don’t have to put up with the annoying service light. Most service stations have a reset button for oil lights, so you’ll just need to go in and ask them to turn it off. But don’t forget to get your oil changed later!

When you bring your car into our Service Center, the process is quick and easy. Our employees will put in the oil you need and reset your car’s computer so the light won’t come back on. This means that when you drive away, you’ll be protected against any damage to your engine. All in all, the service shouldn’t take more than a few minutes.

Why Is It Important to Change Your Car’s Oil?

There are many benefits to maintaining your car, and oil changes are no exception.

Protects Against Friction

Your car needs oil for many functions, but the biggest thing it does is prevent friction. The engine causes metal parts to grind together because of all the force being applied, which means there’s no way your car could run without oil. But why does this matter? Well, even though you can’t see any damage happening inside your car’s engine, over time, it will slowly break down the metal parts.

If you don’t change your oil at regular intervals, then this can cause big problems for your car, truck or SUV.

Optimize Gas Mileage

When your engine doesn’t have to work as hard to get going, you’ll see a big difference in how much gas mileage you’re getting. If your oil is dirty or it’s time for an oil change, then this means that the car has been working harder than it should be to keep everything running.

If you care about the environment and don’t want to waste any more gas than you have to, then it’s time for an oil change.

Better Engine Performance

When your oil is clean and filled with the right type of lubricants, the engine will be able to run smoothly. If your car is running slowly or not at all (which can be a symptom of a faulty oil sensor), then this is a sign that you need to get an oil change right away. You might also experience some other problems, such as the service light coming on or trouble shifting gears.

You will also benefit from a longer engine life. Regular oil changes are essential if you care about your car and want it to be in great shape when you drive it off the lot.

Cooler Engine

Oil plays an important role in regulating the temperature of your engine. When oil is cold, it becomes thick and doesn’t do its job correctly. Instead of lubricating the parts that need it, it will sit on top until enough heat is applied to thin out the viscosity. If you want to keep your car cool during the summer months, make sure you change the oil at least every 5,000 miles.

What Happens If You Don’t Change Your Oil?

When your oil gets dirty, it can’t do its job properly. Old oil doesn’t lubricate your engine anymore and starts to get sticky. This causes all sorts of problems like accelerated wear, which means that you’ll need new pistons, piston rings, valves, or bearings sooner than expected. It’s not an issue that’s easy to fix either. To replace all these different engine parts, you’ll need to take apart the entire engine. Not only will this be expensive, but it could also cause more damage if not done properly.

Your safety is another reason why you shouldn’t neglect your oil. If the oil gets too hot for a long period, then it can catch fire. Burning oil can cause a lot of damage, and you don’t want that to happen!

Synthetic Oil vs. Conventional Oil

If you have a newer car, then synthetic oil might be a good idea because it’s meant to last longer than conventional oil. It also performs better in higher temperatures, which can help prevent your engine from catching on fire. However, using this type of oil in an older model may not be a great idea. Your car needs to adjust to the oil, and over time it might stop working.

Conventional oil isn’t as high-tech as synthetic oil, but it can do pretty much everything you need. It’s an affordable option that doesn’t require too much upkeep either. You’ll know how long your engine can handle conventional or synthetic oil by checking out the owner’s manual, or you can ask the mechanic at the garage.

Oil Change Prices

The cost of your oil change will depend on what type of oil you use and where you go. You can expect to pay around $60-$100 for a synthetic oil change and a few bucks less for a standard one. A lot cheaper than if you wait too long and have to take your engine apart!

The Oil Service Light Is On – What Should I Do?

If there’s one thing you should do after reading this article, it’s to get an oil service done as soon as possible if the service light comes on. Take this opportunity to verify if any other maintenance issues need to be addressed. You need to check for regularly:

  • Worn out tires
  • Brake Discs
  • Fluid levels such as oil, brake fluid, and cooling system (including washer fluid)
  • Lights like headlight, taillight, and turn signals
  • Leaking fluids
  • Wheel Alignment
  • Tire pressure
  • Belts and Hoses


The oil service light can turn on for many reasons but usually comes on due to an oil change. Not only will you save on gas mileage, but you’ll also experience better performance and longer engine life if you take care of your car with regular oil changes.
