9 Things you Wanted to Know About an Oil Change and your 2021 GMC Sierra

Most drivers know they need to change their truck’s oil at some point, but when? The answer is confusing because it depends on driving conditions and your own driving habits. Not only has that, but the synthetic vs. conventional debate further confuses drivers.

Years ago, the industry standard for oil changes was around 3,000 miles. Thanks to improvements in fuel quality, engines, and oil formulations, as well as the development of synthetic oil have stretched out that interval. Modern engines can have intervals upwards of 7,500 or even 10,000 miles. But what is the right answer for your 2021 GMC Sierra?

Why do I need to change the oil in my 2021 GMC Sierra?

The parts inside the engine move incredibly quickly, which generates friction and heat. The engine is lubricated with oil to keep the parts moving without overheating or seizing. It’s a lot like cooking. If you forget the oil, your eggs stick to the pan, and if you don’t use enough oil, the oil burns up.

In an engine, as the oil gets old, it begins to break down and doesn’t do its job as well. An oil change replaces all the old broken down oil and any contaminants in the engine with fresh clean oil. In a worst-case scenario, your engine could seize up completely. To avoid this, it’s important to change your oil. Sanger GMC makes it easy to schedule your Sierra oil change.

Why is Synthetic Oil so expensive? Why should I get it instead of conventional oil?

More manufacturers today design their engines to take advantage of the superior protection and performance of full synthetic motor oil. Conventional motor oil is refined from crude oil as a by-product of gasoline refining, while synthetic motor oil is man-made using chemicals designed to feature only the best properties of crude oil. As a result, synthetic oil contains fewer contaminants, which dramatically lowers the risk of engine sludge and buildup. As a result of being cleaner and more refined, synthetic motor oil will flow better than conventional oil.

In addition to the increased performance, synthetic motor oil lasts longer than conventional oil. So while you may be used to oil changes every 3,000 miles in your old vehicle using conventional oil, in your 2021 GMC Sierra, you’ll be going a lot longer without oil changes!

At Sanger GMC, your 2021 GMC Sierra repair and service specialists serving Sanger, Fresno, Clovis, and surrounding areas, their team of factory-trained technicians can tell you which oil is required for your vehicle and make sure you get the best for your GMC Sierra oil change.

Can I mix synthetic and conventional oil together?

Mixing synthetic and conventional oil isn’t recommended. When you take a high-quality synthetic oil and mix it with an inferior conventional oil, you dilute the cleaning and lubricating power of the higher-quality oil. Conventional oils contain impurities, which the synthetic oil then has to clean out of your engine as well. Although conventional oils contain cleaning additives as well, these are often inferior to the cleaning technology in synthetic oil. Think of it as opening a bottle of soda, pouring half out, and then filling the rest up with water. It might look like soda, might taste a bit like soda, but it’s not quite the same.

This is why it’s important to take your 2021 GMC Sierra to a service shop that puts only the best oil into your truck, such as Sanger GMC.

What kind of oil goes in my 2021 GMC Sierra?

The 2021 GMC Sierra takes 5w30 full synthetic oil. However not all 5w30 synthetic oils are the same. Only the best 5w30 oils meet the dexos1™ specified by GMC. When you go into a “quick lube” store for an oil change, often they only have conventional oil in stock. While it might be the same 5w30 weight, it doesn’t have the same lubricating and cleaning properties that a dexos1™oil contains. If you put lower-quality oil in your GMC Sierra, damage to the engine could occur. When you come to Sanger GMC for a Sierra oil change, they give you the same oil GMC puts in your Sierra from the factory, ensuring that your engine stays in top shape.

How much does changing my oil cost?

Your GMC Sierra Oil change can vary in price depending on where you go. A typical oil change consists of 6-8 quarts of oil, plus a filter. The main factor in the price is the oil cost. Cheaper oil change shops typically use cheaper inferior conventional oil. Only a GMC-certified service center such as Sanger GMC uses GM-certified dexos1™oil. Expect to pay between $70-90 in the Sanger area depending on the engine in your Sierra. However, the price may vary, depending on any special service promotions. When you take your car into a GMC Sierra specialist, you don’t just get your oil changed like at quick oil shops. Your GMC Sierra also receives a four-tire rotation and a Multi-Point Vehicle Inspection, to spot anything that looks out of the ordinary with your 2021 GMC Sierra.

Quick oil shops don’t offer this kind of service. In fact, you might ask, “How much does getting my oil changed at Sanger GMC save me?”

How much oil does my 2021 GMC Sierra need?

How much oil you need for your GMC Sierra oil change use depends greatly on the engine in your truck. A 2021 GMC Sierra with a 2.7L engine uses 6 quarts of 5w30 dexos1™oil. A 3.0L diesel-equipped GMC Sierra requires 7 quarts of 0w20 dexos2™oil. The 4.3L V6 GMC Sierra takes 6 quarts of 5w30 dexos1™oil. All of the V8-model 2021 GMC Sierra trucks take 8 quarts of 0w20 dexos1™oil. Finally, the 2021 Sierra HD with the 6.6L V8 diesel needs 10 quarts of 15w40 dexos1™oil.

As you can see, not only does your service shop need to know how much oil to put in, they need to know the right oil to use. This is why taking your truck to GMC Sierra repair and service specialists like Sanger GMC is always a good call.

How often do I need to change my 2021 GMC Sierra?

An oil change is one of the most important services for your car. GMC recommends getting your 2021 GMC Sierra oil changed every 3000-5,000 miles if you are using conventional oil. Ideally, though, you should be using a synthetic oil that meets the dexos1™ specification.

When using synthetic oil, you should have an oil change every 7,500 -10,000 miles. This exact number will depend on your driving habits. If you drive in severe driving conditions, you may need the oil changed earlier and more frequently. Your 2021 GMC Sierra also comes equipped with an Oil Life Monitor to let you know when it’s time to bring your truck in for an oil change.

What are severe driving conditions?

Severe driving conditions are any of the following:

  • Long periods of frequent idling
  • Stop-and-go driving in heavy traffic
  • Sustained highway driving in extreme hot or cold temperatures
  • Short trips (less than 5 miles) in normal temperatures
  • Long-distance trips at speeds of 50mph or less
  • Regular trips along steep hills or mountains
  • Any trips along with dusty, dirty, or salted roads
  • Any trips that involve towing
  • Any trips that involve transporting items via roof rack or car-top carrier
  • As you can see, virtually all driving we do classifies as severe driving conditions. To maximize the life of your 2021 GMC Sierra, make sure you change your oil regularly.

What happens if I don’t change the oil in my 2021 GMC Sierra?

Although motor oil’s purpose is to lubricate the engine, it also provides other benefits including:

  • Prevents engine corrosion – Additives in synthetic oil prevents rusting and corrosion in your engine.
  • Keeps your 2021 GMC Sierra engine clean – The oil picks up dirt and dust particles and traps them in the oil filter. The filter keeps the oil clean and keeping debris and dirt from getting into the important parts of your engine.
  • Prevents engine wear – Engine parts are moving at very high rates of speed. Proper lubrication prevents them from scraping against each other and wearing themselves out.
  • Keeps your engine cooler – The friction of the engine parts produces heat and any excessive heat can cause major damage to important parts of your engine. As oil flows around the engine heat is carried away to cooler parts,
  • keeping no one part from getting too warm.
  • Improves fuel efficiency – The slipperier the engine parts are, the less for is required to move them. This means the engine uses less fuel and saves you money!
  • Keeps your warranty – Your warranty might not be valid if the manufacturer determines that a failure happened because you let your truck out of oil. The cost of an oil change is a lot less than the cost of an engine!

As you can see, your engine is missing out on a lot of benefits if you don’t change your Sierra truck oil regularly. A few dollars spent on an oil change is a simple way to protect your investment.
