Oil Changes for Your Buick Encore

You know you're supposed to take your Buick Encore to get the oil changed, but do you know what goes on during the process? There is more to it than simply adding new oil to the engine. Your mechanic will drain the old oil and replace it with fresh, new oil. They will then remove your old oil filter, recycle it, and replace it with a new one.

Most shops go above and beyond just changing the oil and filter; many will also check your battery and lights as well as your washer fluid, topping it off if needed. 

Why Do I Need a New Oil Filter? 

Changing the oil filter is just as important as changing your oil. The filter keeps dirt, grime, and other contaminants from entering your motor. Once the filter is full, it can no longer keep those harmful particles away from your engine.

How Often Should I Change My Oil?

The time between oil changes will depend on several factors, including the type of oil used and driving patterns. If you are using conventional oil, you will need to change it every 3,000 - 5,000 miles. However, synthetic oil only needs to be changed every 7,500 - 10,000 miles. 

You should never ignore oil service alerts on your vehicle. Your car detects more than just the mileage. It also perceives your driving habits, such as how hard you drive your vehicle and makes recommendations based on those factors. 

What if I don't Drive My Buick Encore Very Often?

The mileage recommendations can be misleading. If you do not drive your Buick Encore often enough to meet the mileage recommendations for oil changes, you still need to change it twice per year. As oil gets older, it begins to lose its effectiveness. When you run your car, the motor gets hot, removing any excess moisture in your engine. However, if you don't use your vehicle regularly, the oil begins to settle, reducing your engine life. 

Should I Check My Oil Between Changes? 

Even if you are getting the oil changed regularly in your Buick Encore, you still need to check your oil at least once a month. This applies to newer vehicles as well. If you begin to run low before your next maintenance alert, add one of the above-mentioned products to your engine. 

How Do I Check My Oil?

Never check your oil while the engine is hot. Once it has cooled down, pop the hood and find the dipstick. Pull it out and wipe it off. Now, it's time to replace the dipstick all the way and remove it a second time. This time, you will look at the stick and find the oil line. There is no need to worry as long as you can see oil between the two indication lines.

Can I  Add New Oil Instead of Getting an Oil Change?

As mentioned earlier, there is more to an oil change than just adding new oil to your vehicle. Mechanics drain the old oil, which no longer contains lubrication. If you pour new oil on top of the existing oil, the new oil will become watered down and won't properly lubricate your engine. If you continue adding new oil and skipping oil changes, your Buick Encore will likely begin to run hot or blow a gasket. 

Where to Get My Oil Changed

When it's time to get your oil changed, you don't have to take your Buick Encore to a certified Buick dealership. Instead, you can take it to any reputable shop nearby. Walmart offers oil changes at a reasonable price, and you can also visit your local mechanic. However, if your new Encore came with free oil changes, you will need to take it to the proper dealership to receive that service.
