When you buy a car from a GMC dealer, you know you're getting a powerful, reliable, and stylish vehicle. But that's not all you're driving away with; your GMC purchase also comes with top-quality service from an experienced and knowledgeable team! At Crenwelge Motors GMC, we proudly offer customers a tire rotation, brake installation, or oil change whenever necessary. But how often will your GMC need new oil? Let's talk about it today. more Long-time car enthusiasts probably remember when changing your oil was expected every 3,000 miles, regardless of the car's make or model. These days, most engines can handle longer periods between each change: for example, some cars that use fully synthetic oil can go up to 15,000 miles! How long can your GMC car go before you need to refresh the oil? According to the manufacturer, most GMCs can drive about 7,500 miles before you need to change the oil. However, it's important to note that certain driving conditions can affect your oil life. Therefore, you may need to change your engine's oil more often depending on your driving habits. Conditions That Affect Oil Life Car oil helps lubricate your engine, preventing friction that can cause damage over time. But the harder your car works, the more oil your engine will burn through, ultimately reducing your car's oil life. You may need to change your car's oil more often if you regularly use your GMC for the following activities: Off-roading Heavy towing Commercial driving Racing Luckily, GMC makes it easy to keep tabs on your vehicle's oil life. Many models are equipped with an Engine Oil Life Monitor, which analyzes mileage, running temperature, and other key factors to tell you when your car is due for new oil. Remember To Check Your Oil Levels While the Engine Oil Life Monitor can help you determine the best time to change your oil, it's important to remember that it doesn't track your car's oil level. That's why we recommend checking your car's oil level with a dipstick at least once a month. If your oil levels are low and you're not due for a change, it's wise to bring your car to your local service center to check for leaks or other issues. A GMC car or truck is built for hard work and harder play, but keeping your vehicle in great shape requires regular maintenance. Our team can help you find the perfect vehicle and give you the service you need to keep it running like a champ. Visit Crenwelge Motors GMC in Kerrville, TX to find your next dream car!

There are many car electrical problems that can happen throughout your car's life, and these should always be repaired at the GMC dealer, as the dealership employs mechanics who are always up-to-date on how to diagnose and repair the latest GMC models. Let's look at some of the most common problems that you'll need to head to the dealer to fix. Photo by: Julia Avamotive via pexels.com more 1. A Dead Battery Your battery is the backbone of your car's entire electrical system. Without it, none of the car's electrical components can work at all. When a battery is faulty, it can sometimes be repaired, but most damaged batteries will need to be replaced. Old batteries also need to be replaced to keep your car running in top shape, so make sure you get yours replaced at your dealer regularly. 2. A Failing Alternator Your alternator is your battery's best friend. It charges the battery while you drive and converts mechanical energy into electric energy. When the alternator is failing, you'll notice your car having various electrical issues. Your headlights could waver between being too dim and too bright, your engine could stall, and many more issues can crop up when the alternator is faulty. 3. A Broken Starter Motor The starter motor is a small but essential part of your car's electrical system. The battery powers this motor, and the motor, in turn, switches on your car's combustion engine. Even if your battery and engine are working fine, your car won't be able to start if the starter motor itself is broken. You'll hear a click when you turn the key and have a broken starter motor, but the car won't start. 4. A Faulty Fuse Box Most of the time, the fuse box won't need to be replaced during your car's lifespan. The fuses inside may blow occasionally, but those are cheap and easy to replace. However, if your fuses become loose, the fuse box develops water staining, or your fuses start to blow regularly for no apparent reason, then the entire fuse box might need to be replaced. 5. A Bad Spark Plug Each cylinder of your engine has a spark plug to go with it. These plugs are responsible for igniting the fuel that powers up your engine. If one of these plugs stops working properly, then you'll notice your car doesn't start as powerfully as it did before. You might also notice trouble while idling, reduced gas mileage, and inconsistent power while driving. You need to get your bad spark plug or plugs replaced at the dealer. These problems can be jarring to experience, but they're generally easy to fix. Visit Crenwelge GMC Kerrville so we can take care of these issues promptly and get you back out on the road.

Your car's has a myriad of components and numerous interconnected systems. Regular engine services are the easiest way to prevent a problem, as a service enables us to check and replace components before they wear or become damaged. Your GMC dealer in Kerrville, TX, can fix any possible problem. We'd like to give you some examples of engine problems we can repair. Photo by: Anna Shvets via pexels.com more Engine Knocking A strange knocking sound under the hood is always a sign of trouble. When your engine has the correct balance of fuel-to-air, and the spark plug ignites the mixture, it burns in a carefully regulated way. Part of the mixture ignites, which creates a shockwave that ignites another part of the mixture, and the process continues until all the mixture in the cylinder has been consumed. The knocking sound is caused when the fuel-air mixture burns unevenly, and the shockwaves created as it burns happen irregularly. This sound is not only annoying, but it's a warning that you will suffer to the cylinders and pistons if the problem isn't fixed. Some causes of this problem are worn spark plugs, a build-up of carbon in the intake manifold, and low-octane fuel. We'll examine your engine to find the cause of the problem and fix it. Illuminated Warning Light There are many different warning lights on your dash. When your engine starts, all the lights illuminate and then go dark. If the engine warning light stays on, there's something wrong with your engine. The warning light doesn't identify a specific problem, but it does mean that you need to contact us ASAP, so we can investigate. We can identify the problem by connecting your car's computer to our diagnostic system. If something goes wrong, engine sensors will inform your computer, and the computer logs the problem with an error code. Once we have the error code, our expert technicians will repair the cause of the problem. Once the problem is fixed, the engine light will go dark again. Old Oil We all know that an engine needs oil. Oil lubricates all of your engine's components and helps to protect them against friction damage. Over time, engine oil accumulates dirt and minute debris, which reduces its speed. Slower moving oil can't work as effectively as it should, and it can even cause blockages in your engine. If the oil needs replacement, the oil can-shaped warning light on your dash will illuminate. This is a sign that the oil needs to be replaced. An oil change is a quick process that enables your engine to work more efficiently and prevents damage. If your engine isn't working as well as it should, call us right away at Crenwelge GMC Kerrville.

Your car battery is essential to start your car, and when your car is parked it maintains power to the alarm system, door lights, and other electrical peripherals. Modern car batteries last longer, but they will eventually wear out and no longer be able to be recharged. As your GMC dealer in Kerrville, TX, we'd like you to the signs that you may need a new car battery before the old one fails. Photo by: pixabay.com more Takes Longer to Crank the Engine Your battery is responsible for providing the power to start your engine. If your battery is good, your engine should crank and start as soon as you turn the key. If there is a delay in cranking this can be the sign of a dying battery, but it could as be a sign of a worn alternator. Your battery has a finite life, and on average it will need to be replaced every 3-5 years. As the battery ages, it becomes more difficult to recharge it and it also no longer charges to its full capacity. If your battery is at least five years old, it may not be able to maintain sufficient charge to crank your engine immediately. The battery may need several attempts to build up enough charge to crank your engine. Our technicians can easily test your battery and recommend a choice of replacement batteries if it is necessary. Check Engine Light The check engine light is a great warning sign that something is wrong with your car. Numerous sensors are attached to your car's vital components to monitor them, and the sensors detect subtle changes that you may not immediately be aware of. When a change is detected by one of the sensors, the check engine light will light up. The check engine light doesn't necessarily mean that you have a battery problem, but we advise contacting our service department so we can find and repair the source of the problem. An Old Battery As mentioned above, the average life of a battery is 3-5 years. Environmental factors and driving habits can also play a part in reducing battery life. The alternator charges the battery, but as a battery ages, it becomes more difficult to recharge. An old battery will also lose its ability to fully charge to its original level as it starts to degrade. We advise that your battery be tested at least every three years to ensure that it is functioning correctly. Our technicians will also be able to check the battery for any damage or signs of wear that could cause a potential problem at a later date. A dead battery can leave you stranded on the side of the highway with no help available. If you are in the Kerrville area, we want to make sure that never happens to you. If you experience any problems with your battery, call our service department right away at Crenwelge Motor

Do you hear unfamiliar sounds, smell weird odors, notice puddles under your car, or see smoke from under the hood or the exhaust? These are all tell-tale signs that your vehicle needs maintenance from a qualified technician. When you experience any of the following issues, it's time to make an appointment at your Kerrville, TX, GMC Service Center ASAP before you get stranded next to the road. Photo by: pixabay.com more 1. Dashboard Warning Lights are On If you notice that any of your dashboard warning lights are illuminated, there is a problem. Something is not working as it should and should be dealt with as soon as possible. Schedule a maintenance appointment at your dealership to ensure that a qualified technician can identify the issue and fix it before a minor problem results in costly repairs. 2. You Notice Fluid Leaks If you have to top up your vehicle's fluid levels more often, it could be caused by a fluid leak. The fluids keep the moving parts lubricated and cool and reduce friction and heat. Check under your car for puddles. If you notice it's brown or dark brown, it's an engine oil or brake fluid leak, transmission fluid is reddish-brown to orange, coolant is bright orange, yellow, red, green, or blue. If it's red, it's power steering fluid. Ask your technician to take a look as soon as you can. 3. There Are Strange Noises The sounds your car makes can be important warning signs that there might be an issue somewhere. If you hear squealing sounds, it's most probably the brake pads that need to be replaced. If you don't get them replaced, you will soon hear grinding from the calipers against the rotors. A damaged exhaust will make a rattling sound, and clunking is usually a bad shock absorber. Humming sounds come from worn universal joints or wheel bearings, and if you hear screeching, it could be the serpentine belt. If you hear new noises you are not familiar with, it's best to ask your technician to take a look. 4. You Smell Unpleasant Odors Strange smells that you've not noticed before are tell-tale signs that your vehicle needs maintenance. If you smell rotten eggs, it's a fuel system problem, and burning and electrical odors are caused by overheating. If you catch a whiff of gasoline, you might have a gas leak or a faulty injector or gas cap. Exhaust fumes are caused by an exhaust system leak, and a loose belt or hoses will give off a burning rubber odor. 5. You See Smoke Smoke from under the hood or from the exhaust is a reason for concern. If you see white smoke, it's caused by overheating and blue smoke by worn or damaged seals. If the smoke is coming out of the exhaust and it's white-gray, it could be a leaking head gasket, a cracked block, or cylinder head. Blue exhaust smoke is from an oil leak, and black smoke is caused by either a faulty fuel injection system, clogged air filter, or a blocked manifold. 6. Your Tires Are Worn or Damaged For your own safety and the safety of your passengers, you should regularly check the tread depth and inspect your tires for damage such as bulges and cracks. If you notice any damage on the sidewalls or the tread is worn, you need to replace your vehicle's tires. To ensure that your tires last longer, keep them inflated to the correct pressure levels and have the tires rotated regularly for even wear. If you notice any warning signs, schedule an appointment at your dealership ASAP to avoid further damage and expensive repairs. Contact Crenwelge Motors GMC today, and our qualified and experienced technicians will ensure that your vehicle runs smoothly.

The engine of your vehicle needs oil for lubrication to run smoothly and efficiently. Over time, chemical components of the oil can break down. Routinely changing your oil can extend the life of your engine, improve your gas mileage, and reduce emissions. In buying or leasing a new GMC, you are eligible to have your first service visit covered. Tire rotation and Multi-Point Vehicle Inspection are included in this service and are also offered with any subsequent GMC oil change. Photo by: Steady Content When To Have a GMC Oil Change Most GMC vehicles come with a built-in technology called an Oil Life System (OLS). Based on the number of revolutions your engine has completed, its temperature, and miles driven, this system will calculate the unique percentage of life your oil currently has left. When your vehicle sends out an alert that your oil has 15% life left, it is time to schedule an oil change service. A GM-certified professional will be able to determine which type of oil is best suited to your vehicle. They will then proceed to drain all of the old oil out and replace it with fresh, new oil. Tire Rotation At an oil change service, it is often recommended to have your tires rotated as well. At GMC, qualified experts will rotate all four tires to balance the wear and prevent the loss of tread depth. In checking the alignment and balance, they will be able to help your vehicle maintain optimal performance and safety. Multi-Point Vehicle Inspection This inspection can be a valuable addition to your oil change. Not only will the technicians focus on the engine but they will expand their view to the whole system of your vehicle. A Multi-Point Vehicle Inspection includes a comprehensive analysis of the following components: Wiper Blades and Glass The wiper blades in the front and back of your vehicle will be inspected for wear, and the glass of all windows will be looked over for any sign of cracks or chips. Brakes Brake tests are performed checking all hoses and lines, while measurements are taken of the front and rear brake pads to assess the amount of wear and condition. Battery A visual scan, connection cleaning, and battery connection test will take place to make sure that your battery is strong. If the battery is not functioning properly you could be at risk of being unable to start your vehicle. Fluid Levels The Multi-Point Vehicle Inspection also includes scrutiny of all of the fluid levels in your vehicle. Fluids such as windshield washer liquid and brake reservoir fluid will be filled to factory specifications. OnStar While OnStar may not be a service that you use every day, the last thing you want is to get stuck without it. The experts at GMC care about your safety more than anything else, and with every inspection, they will make sure that your OnStar system is set up and working correctly. It is important to have oil checks regularly for your vehicle's engine health and complete safety. Each time you need an oil change for your GMC vehicle is an opportunity to get the best quality service.
