What Is Included in an Oil Change Near DeSoto

A dealer oil change is built around GM’s published maintenance schedule and covers considerably more than the oil itself. You can also review our GMC Certified Service oil change page for program details.

Combining the oil service with the multi-point inspection is the practical value of the visit. Filters, suspension bushings and undercarriage components get eyes on them before minor wear becomes a repair order.

Why DeSoto Drivers Service Their GMC at Legacy GMC of Waxahachie

How Often Does Your GMC Need an Oil Change?

GM’s published maintenance schedule calls for an oil and filter change every 7,500 miles, or as indicated by your vehicle’s Oil Life System. The Oil Life System is the one to watch. It is an algorithm rather than a mileage counter, and it calculates remaining oil life from a combination of engine revolutions, engine temperature and miles driven. That is why two GMC vehicles with identical odometers can call for service weeks apart.

Driving conditions move that calculation:

• Frequent short trips keep the engine from reaching full operating temperature, letting moisture and unburned fuel collect in the crankcase.
• Heavy towing and hauling sustain high oil temperatures, accelerating thermal oxidation and viscosity breakdown.
• Extended idling adds engine revolutions without adding odometer miles.

When the system determines the oil has degraded, a CHANGE ENGINE OIL SOON message appears — and GM’s instruction is to have the oil changed within the next 600 miles, not whenever it is convenient. Separately, GM requires the oil and filter to be changed at least once a year regardless of what the percentage reads.

One more thing: the system must be reset after every oil change. A system that is not reset stops tracking accurately, and you lose the warning that protects the engine.

Common Questions About GMC Oil Changes

How often should I change the oil if I tow frequently?

Follow the Oil Life System rather than a fixed mileage number. Sustained trailering raises internal combustion temperatures and accelerates oil degradation, so the system will call for service earlier than it would on a lightly used vehicle. Watch for the CHANGE ENGINE OIL SOON message and book within 600 miles of seeing it.

What happens if I use non-dexos certified oil in my GMC?

GM specifies dexos-certified oil for its engines, and gasoline and diesel certifications are not interchangeable. Non-certified oils may lack the additive chemistry required to prevent low-speed pre-ignition in direct-injected engines, and consequences can include accelerated sludge formation and premature wear. Using unapproved fluids may also affect factory powertrain warranty coverage.

Does a new GMC come with a complimentary first maintenance visit?

GMC currently includes a first maintenance visit on new vehicles, covering an engine oil and filter change, tire rotation and a multi-point inspection. Coverage terms are set by General Motors and are subject to change — confirm current eligibility for your VIN with our service team before your visit.

Where do I check my remaining oil life?

On the Driver Information Center in your instrument cluster. Use the steering wheel controls to reach the Info menu and select Oil Life for a percentage readout from 100 percent down to zero.

Where can I find the oil capacity and oil type for my truck?

Your owner’s manual and the engine oil fill cap both list the specification your engine requires. For GMC Sierra 1500 owners, our Sierra 1500 oil type and capacity guide breaks it down by model year, or our service team can confirm it for your VIN.
