2022 gmc sierra 5.3 oil change

Why are oil changes necessary?

Oil plays a crucial role in protecting the engine’s internal parts from damage, keeping the engine cool and preventing contaminants from accumulating inside the engine. Throughout the normal course of your car’s operation, the oil’s ability to perform these crucial roles is minimized due to contamination from moisture and combustion gases. If you take a lot of short trips where the engine doesn't reach full operating temperature on a regular basis, the oil will become contaminated more rapidly requiring more frequent oil changes.

The oil filter also needs periodic replacement because over time it loses its ability to clean the oil as the engine is operated. If the oil filter is not changed regularly it can degrade and in severe cases even disintegrate, which can plug up oil passages and lead to engine damage or failure.

Can I drive without changing the oil?

It is possible to drive a vehicle without an oil change, but driving a vehicle after the specified service interval has passed is not recommended. Over time engine oil breaks down from use and is contaminated by the combustion process (blow by gasses). The oil and filter should be changed as soon as is convenient to maintain protection of internal engine components.

When is it time for an oil change?

Oil should be changed regularly to prevent internal engine damage and breakdown. Manufacturers differ in their recommended guidelines for how often to change engine oil and oil filters.

The traditional rule of thumb is that engine oil should be changed every 3,000 miles to keep the engine healthy and to prolong its life. Most modern cars do not require the old "3 Months or 3000 Mile" service interval. In some cases it is several times that, but at least once a year is recommended, no matter how little you drive.

Some cars are also equipped with maintenance computers that let you know when the oil life is depleted, or when the specified maintenance interval has passed. This notification can come on more often depending on environment or driving conditions such as towing, or long periods of stop and go traffic.

Changing engine oil is one of the most important maintenance tasks associated with owning a truck, SUV, or crossover. Knowing when to change your oil is incredibly important, and the Engine Oil Life Monitor, found in most new GMC models, not only helps owners keep their GMC properly maintained, but also maximize their maintenance investment.

An engine contains thousands of moving parts, like valves, pistons, camshafts, and so on. These parts require proper lubrication in order to function properly and prevent damage. The chemical compounds found within engine oil help give these parts sufficient lubrication, but over time, they wear down and are less effective. An oil change, which drains old oil and replaces with fresh new oil, helps to keep an engine properly lubricated.

Years ago, engine oil changes were typically prescribed at a set interval, which was usually based upon mileage. It wasn’t uncommon to see owner’s manuals and maintenance shops advising drivers change oil every 3,000 or 5,000 miles.

But those intervals aren’t the best means to determine if a truck or SUV truly needs an oil change. As no two drivers are alike, vehicles can be subjected to a wide range of conditions, even if they’ve traveled the same number of miles. A vehicle that regularly carries heavy loads or tows trailers daily may put more strain on the engine, and need an oil change before it reaches a 3,000 mile interval. Conversely, a vehicle used for mild highway driving in warm climates may have oil that’s still good for another couple thousand miles or so.

That’s where the Oil Life Monitor comes in. Although it doesn’t measure the level of engine oil (you’ll still need to regularly check that on the dipstick underhood), it helps provide a realistic guide as to when an engine needs its oil changed. Depending on the vehicle and the conditions experienced, the oil in a GMC may not need to be changed for up to 7,500 miles or a year.

Based on data collected over decades of extensive powertrain testing, GM engineers have developed sophisticated algorithms that reflect how time, engine speeds, engine temperatures, load, and other factors affect oil life. By plugging in real-world data for those variables, the Oil Life Monitor can accurately calculate when an oil change is needed and display the remaining oil life within the Driver Information Center.

For more information on the Oil Life Monitor, refer to your GMC’s owner’s manual or speak with your GMC Certified Service consultant.
