“When Should I Schedule My Service?”
When It’s Time
Whether it’s by months or by miles, there are two maintenance schedules to be aware of. The first is the lifespan of your engine oil. Keep in mind that mileage isn’t the only indicator to change your oil; engine oil can degrade over time in the vehicle. So if you’re running up against the time limit on your oil change, you should schedule a maintenance appointment for an oil change to keep your engine clean and healthy.
Your vehicle will also require regular maintenance at specific milestones in its lifespan, usually measured in miles. Because each vehicle is different, you should check your owner’s manual (or simply call our friendly and qualified service team and ask). Mileage services usually involve more work than a simple oil change, offering vehicle health inspections, filter service, brake maintenance, and more.
When It Asks
GMCs are pretty smart. In fact, with the myGMC mobile app and a compatible GMC, you can get vehicle status at a glance, along with fuel and tire pressure levels. The app can also notify you if the vehicle needs maintenance, whether you’re creeping up on a mileage-based service or something has changed within the vehicle. Of ​course, dashboard lights can also indicate maintenance needs.
When Something’s Amiss
Even with great preventive maintenance, things can go amiss. Debris can get lodged in brake calipers, engine air filters can get clogged early in particularly sandy, dusty, or pollen-heavy areas, and more. If you notice a change in performance, a change in sound, a new and unexplained vibration, or anything else that just doesn’t seem right, your best bet is to schedule a maintenance visit right away and let our qualified team take a look.
What Will the Team Do for My GMC?
While ultimately the answer to this question is “whatever it needs”, the specifics are more dependent on your vehicle: when it is in its lifecycle, if you’re coming in for preventative maintenance or a current issue, and more. Our team can offer oil changes, tire services, brake services, battery checks, or even engine and transmission work if need be. And peace of mind comes standard with a Multi-Point Vehicle Inspection from our certified service experts.
But no matter what you come in for, our GMC-certified technicians are on hand with advanced diagnostics tools to pinpoint issues and get them fixed right away. So go ahead and schedule your next service appointment at Oxendale GMC in Flagstaff, AZ, and let our team care for your GMC.
