Spark Plug Maintenance: Replacement and Performance Tips for GMC Owners

Spark Plug

Spark plug maintenance is a routine task that helps a vehicle perform well. Wilson GMC Stillwater in Stillwater, OK offers spark plug inspection and replacement for all drivers. Healthy spark plugs keep an engine running in a smooth and reliable way. Contact the service team to learn more about the condition of your vehicle.

Function of Spark Plugs

Spark plugs create a spark to start the fuel and air mixture in the engine cylinders. This action provides the power that turns the wheels of the car. When the parts are in good condition, the fuel burns at the correct time. This leads to steady speed and better fuel use. Worn plugs make the engine work harder and can cause the vehicle to shake.

Signs of Spark Plug Wear

A driver may notice signs that spark plugs need attention. One sign is a rough idle when the GMC is stopped. Engine misfires can also happen during speed changes. This feels like the car is hesitating when the driver uses the gas pedal. A decrease in fuel mileage is another common symptom. A check engine light may appear on the touch screen in some models. If the light is on, a technician should check the vehicle.

Impact on Engine Performance

Ignoring maintenance can lead to other engine problems. Worn plugs can cause unburned fuel to enter the exhaust system. This can damage the catalytic converter. Repairing a catalytic converter is a more complex task than replacing spark plugs. Misfiring cylinders also put stress on other parts. This increases the amount of fuel used.

Maintenance Tips for GMC Vehicles

Drivers should follow the service schedule in the owner manual. When the plugs are changed, the technician should also look at the ignition coils and wires. These parts work with the spark plugs to start the engine. Always use parts that match the specifications of the GMC. Using the wrong plug type can cause performance issues.

GMC Wiper Blades: A Small Part with an Important Job

Windscreen wipers are wonderfully uncomplicated things. Material moves across a piece of glass and removes the water. Yet when the blade deteriorates, this component can make driving through a heavy Oklahoma storm considerably more difficult. GMC windshield wiper blade replacement is therefore worth treating as genuine maintenance, not something remembered only when the first streak appears directly in your line of sight. Why Worn Wipers Deserve Your Attention A good wiper should clear water smoothly and consistently. As the wiping edge ages, exposure to sunlight, temperature changes, dirt, and repeated use can cause it to deteriorate. The result can be streaking, smearing, skipping, or sections of the windscreen that simply aren't being cleared properly. Damaged blades can also expose harder components that may contact the glass, creating the possibility of windscreen damage. If visibility has started deteriorating during rain, arranging GMC wiper blade service makes considerably more sense than waiting for the next scheduled oil change. Don't Replace Them by Calendar Alone Six to 12 months is commonly given as a general replacement range for wiper blades, but condition is more informative than an arbitrary date. Oklahoma heat and exposure to sunlight can be hard on wiping materials, while frequent storms mean the blades may also see substantial use. Inspecting them periodically during routine GMC maintenance is therefore a better approach. Look closely at the wiping edge for cracking, tearing, stiffness, or separation, then pay attention to its performance during rain. A blade that's already failing to clear the glass properly has answered the replacement question for you. Streaking and Chattering Are Telling You Something The warning signs aren't especially subtle. Persistent streaks or smears can indicate that the wiping edge is dirty, worn, or damaged. Chattering or skipping across the windscreen can result from deterioration, contamination, or problems preventing the blade from maintaining consistent contact with the glass. Squeaking may also justify an inspection, particularly if it continues on a properly wet windscreen. Before assuming replacement is necessary, clean the glass and blades appropriately and inspect them for damage. If performance remains poor, GMC windshield wiper replacement is a straightforward next step. Getting the Correct Blade Matters The correct dimensions and attachment can vary by GMC model and model year. Genuine GMC parts and compatible replacement blades can be selected for the individual vehicle, while a GMC Certified Service technician can confirm fitment and install them correctly. Make Wiper Blades Part of Your GMC Maintenance Wiper replacement is quick enough to combine with other GMC maintenance services. If your vehicle is already due for an oil change, tire rotation, battery inspection, or another service, asking for the wipers to be checked adds little complication to the visit. Owners can also explore current GMC service specials or contact the GMC parts department when replacement blades are needed. Schedule GMC Wiper Blade Service in Stillwater, OK If your GMC wipers are streaking, skipping, chattering, or showing visible damage, Wilson GMC Stillwater can help drivers around Stillwater, OK, replace them with properly fitted blades. Visit our service center for wiper replacement and other routine maintenance, explore available Genuine GMC parts, or schedule a service appointment online to keep your view of the road clear when Oklahoma weather decides not to cooperate.

2026 GMC Yukon

2026 GMC Yukon: Space, Comfort & Family

Full-size SUVs can help solve space problems, and the 2026 GMC Yukon gives Stillwater, OK, families two ways to do it. The Yukon measures 210.1 inches long and offers up to 122.8 cu. ft. of cargo capacity. Yukon XL stretches further to be approximately 225 inches and increases maximum cargo room to 144.5 cu. ft. Both can seat up to 8 passengers depending on configuration. But the important difference isn't maximum capacity with the seats folded. It's what happens when the family fills all 3 rows and still expects the luggage to come along. Behind its third row, Yukon provides 25.5 cu. ft. of cargo space. Yukon XL has 41.5 cu. ft. That's an impressive amount of additional cubic feet before folding a single passenger seat, which is precisely where the longer body earns its keep. Fold the third row and capacity increases from 72.5 to 93.6 cu. ft.; fold the second as well and the comparison becomes 122.8 versus 144.5 cu. ft. Bigger outside, yes, but importantly, bigger in places families can use. The 5.3L V8 produces 355 hp and 383 lbs. ft. of torque and provides the traditional V8 starting point. The available 6.2L V8 raises output to 420 hp and 460 lbs. ft. of torque, making it the horsepower leader. Then there's the 3.0L Duramax® Turbo-Diesel with 305 hp and 495 lbs. ft. of torque. All pair with a 10-speed automatic transmission. Families comparing Yukon powertrains should think about towing and vehicle use before simply choosing the largest horsepower number. Yukon Elevation includes heated front and second-row outboard seating. Higher trims can add heated and ventilated front seats, upgraded leather appointments, and additional power-adjustable equipment. Available Magnetic Ride Control and Air Ride Adaptive Suspension add another layer to the experience by changing how this large SUV responds to varying road conditions. On something this substantial, suspension technology can be more meaningful than another decorative cabin feature. A large diagonal infotainment display dominates the dashboard for your infotainment needs. A 15-inch Head-Up Display and rear-seat media system are also available. Available Super Cruise® adds hands-free driver assistance on compatible roads. Properly configured Yukon models can tow up to 8,400 lbs., giving owners room for substantial recreational trailers. A maximum tow rating tells you what a properly configured SUV can handle; trailering technology helps with the business of hitching, maneuvering, and driving with that load attached. Choose a New Yukon in Stillwater, OK Today Standard Yukon is a great pick for families wanting 3 rows and substantial cargo capacity without the XL additional length. Yukon XL becomes compelling when the third row stays occupied and cargo still needs somewhere to go. Our GMC dealership in Stillwater, OK, can help shoppers compare new Yukon and Yukon XL inventory, available trims, engines, financing options, and trade-in opportunities. Put your family in both, look behind the third row, and see which size is right for you. Schedule a test drive online today and feel the space firsthand.

GMC Truck Maintenance Checklist: Be Ready for Your Next Road Trip

Planning a road trip is exciting, but before you take on the road, it's important to make sure that your GMC truck is for the trip. A solid GMC truck maintenance routine before you leave can mean the difference between a smooth adventure and an unexpected roadside stop. If you're driving to someplace close to Stillwater, Oklahoma, or heading cross-country, this checklist will make sure your truck is in top shape before you go. Check Your Fluids First One of the important steps in any truck maintenance routine is checking your fluid levels. Before hitting the road, look at your engine oil, coolant, brake fluid, power steering fluid, and windshield washer fluid. Low or dirty oil can cause serious engine wear over long distances. If your GMC truck is due for an oil change, it's best to get that done before your trip rather than during it. Inspect Your Tires Carefully Check the tread depth on all four tires and look for any visible damage like cuts, bulges, or uneven wear. Don't forget to check the tire pressure, including the spare. Underinflated tires affect fuel efficiency and handling, which matters a lot on a long haul. Test Your Battery and Electrical System Have your battery tested if it's more than three years old. Also check that all exterior lights are working, including headlights, taillights, brake lights, and turn signals. Replacing a bulb before your trip is a simple fix that keeps you safe on the road. Review Your Brakes If you've noticed any squealing, grinding, or a soft brake pedal on your GMC truck, have a technician look at the pads and rotors before you leave. Even if things feel fine, a quick inspection as part of your regular truck maintenance is always worth it. Pack an Emergency Kit No maintenance checklist is complete without preparing for the unexpected. Road conditions can change quickly. Keep a basic emergency kit in your truck that includes jumper cables, a flashlight, a first aid kit, a reflective triangle or flares, and a tire inflation kit.
