2015 GMC Sierra engine oil capacity

To begin, we'll need to establish how much engine oil is required for a 2015 GMC Sierra.

Your GMC 5.3L and 6.2L V8 engines hold 8.5 quarts of oil while the 6.0L V8 engine holds just 6 quarts of oil. Be sure not to confuse the displacement of your engine with its capacity. The displacement is the amount of air and fuel drawn into each engine cylinder (either 5.3L, 6.0L, or 6.2L, in the case of the 2015 GMC Sierra), while the oil capacity is the amount of oil required to keep the engine working smoothly.

If you don't know the difference, you might drastically underfill your engine when changing the oil, causing severe engine damage.

What kind of oil does a 2015 GMC Sierra need?

Now that you've gained a better understanding of oil capacity, let's talk about the best type of oil for your Sierra.

Wherever you shop, you're bound to be inundated with tons of different oil types for sale. If you are shopping for oil in your 5.3L or 6.2L engine, you should just keep your eyes out for high-quality SAE 0W-20 oil.

However, if you are buying oil for your 6.0L engine, the Owner's manual recommends using SAE 5W-30 motor oil. This is the oil type recommended by

GMC

, and no one knows the car better than the manufacturer.

The "W" stands for winter, and the 0 that precedes it indicates that this mix flows smoothly even in chilly weather. The number 20 following the "W" indicates a moderate viscosity (or thickness) while the engine is running at its regular operating temperature.

The ideal oil for a 2015 Sierra is, at its most basic level, thin enough to flow easily during cool morning starts while remaining thick enough to keep the engine cool and lubricated while running.

How often to change oil on a 2015 GMC Sierra

GMC recommends changing your Sierra's oil every 3,000to5,000 miles to keep your car running like new.

Regularly checking your oil level and keeping track of prior oil changes can help guarantee you never go too long without adding new oil. Even if you don't drive frequently or keep your car's mileage low, you need to replace your oil every six months to protect it from becoming too sludge-like.

You can also keep an eye out for the following indicators that your Sierra needs an oil change:

How to change your oil and oil filter

Gather everything you'll need before you begin changing your oil. You'll need to have a socket wrench, a drain pan, and a filter wrench. Remember to replace the oil filter and use some fresh 0W-20 (or 5W-30 depending on your trim) engine oil!

Start the engine, and let it run for about five minutes, or until it achieves the temperature needed for regular operation. Then, turn off the engine and proceed as follows:

Position yourself beneath the engine and place your drain pan below the oil drain plug

Remove the oil plug with your socket wrench and allow the oil to drain

Locate your oil filter and remove it with your filter wrench to drain any extra oil

After cleaning the filter mounting surface with a rag, screw in your new filter

Refill the engine with the right amount of oil

After changing your oil, it’s a good idea to turn on your car and let your engine run for about 30 seconds before you check the oil level. This will give you a more accurate measurement, and you’ll be able to top it off if necessary.

That's all there is to it! Check your new oil level with a dipstick to ensure you have filled the correct amount, then make sure your

is turned off. Finally, start the engine to ensure there are no leaks.

When it comes to cleanup, never pour old, contaminated oil on the ground or in the trash. Place it into a sealable container and transport it to your local recycling facility for proper disposal.
