GMC & Buick Maintenance Schedules Explained

When you invest in a quality truck or SUV, you want it to last as long as possible while giving you many years of service. Whether you drive a GMC truck or a Buick SUV, we have experience in the maintenance routines that matter. 

In this blog, the team at Thompson Sales shares what you need to know about taking care of your GMC or Buick. Use these practical insights to keep your vehicle on the road without a hitch. Our service team will cover the mileage intervals between service visits and what services we take care of during each appointment.

What Is the GMC & Buick Maintenance Schedule?

Many vehicles, including GMCs and Buicks, can hit 200,000 miles or go strong for 12 years with proper care. That’s a lot of miles and years of worry-free driving. Simple things like regular oil changes, checking fluids, and monitoring your tires can make a huge difference.

You don’t need to be an expert to keep your car going. Follow the maintenance schedule laid out in your owner’s manual. 

This schedule is the manufacturer’s roadmap, outlining the recommended service intervals and tasks to ensure your vehicle stays reliable for the long haul.

Maintenance by Mile Interval 

Every 7,500 Miles

• Oil Change
• Tire Rotation
• Brake Inspection

Every 15,000 Miles

• Oil Change
• Air Filter Replacement
• Cabin Air Filter Replacement
• Check the Battery

Every 30,000 Miles

• Oil Change
• Transmission Fluid Service
• Coolant System Check
• Brake System Check

Every 45,000 Miles

• Oil Change
• Spark Plug Replacement
• Suspension Inspection
• Power Steering Fluid Service

Between 30,000 and 45,000 miles is when we typically recommend car owners start to budget for replacements on parts showing signs of wear from natural daily use. Our technicians will let you know if the brake pads, tires, or the 12-volt battery must be replaced soon. You might also need new brake fluid.

When you reach 60,000 to 90,000 miles, your vehicle may need a coolant flush and fill to keep the radiator working properly. Regular service appointments are the key to preventing breakdowns because our team understands your Buick or GMC inside and out.

Remember, these are general guidelines, and specific maintenance requirements may vary depending on your vehicle’s make and model.  Always consult your vehicle’s owner’s manual for manufacturer-recommended maintenance intervals and services.

What Happens During Each Buick & GMC Service Appointment?  

The GMC and Buick maintenance schedule typically entails a few components.

Oil Changes and Fluid Checks

Regular oil changes are the backbone of any maintenance schedule when you own a vehicle with an internal combustion engine. Following the recommended oil change intervals specified in your owner’s manual is crucial to the longevity of your engine. We highly recommend full synthetic oil changes with a new OEM oil filter to ensure your Buick or GMC vehicle stays in top condition.

Alongside oil changes, checking and topping up other essential fluids like transmission, brake, and coolant are also part of the routine. Proper fluid levels are vital for running various components in your GMC or Buick.

Tire Maintenance

Keeping an eye on your tires is another essential aspect of the maintenance schedule. Regular tire rotations, wheel alignments, and maintaining the recommended tire pressure help ensure even wear and optimal traction. Well-maintained tires improve fuel efficiency and contribute to a smoother and safer ride.

Brake Inspections

Brakes are a critical safety component. Routine inspections are necessary to catch any issues early on. The maintenance schedule typically includes brake checks, ensuring that brake pads, rotors, fluid, and other components are in good condition. Addressing brake issues promptly not only ensures safety but can also prevent more extensive and costly repairs.

Filter Replacements

Engine air filters and cabin air filters all play crucial roles in the performance of your GMC or Buick. These filters prevent contaminants from entering the engine and the cabin, keeping both areas clean. Following the maintenance schedule means regularly replacing these filters to maintain optimal air quality and engine efficiency.

Additional Considerations

The specific maintenance tasks and intervals can vary based on your vehicle’s model and usage. For example, if you drive a lot in dusty conditions, your air filter may need to be replaced more frequently. Driving on gravel or dirt roads could lead to more tread wear on the tires.

Some schedules may include inspections of belts, hoses, and spark plugs, among other components.  Regular, proactive maintenance not only extends the life of your vehicle but also contributes to a smooth and trouble-free driving experience. Remember, a well-maintained vehicle is a reliable one that lasts a long time.

Why Oil Changes Are Important for Your GMC Vehicle

Regular oil changes are a fundamental aspect of vehicle maintenance. They ensure your engine operates smoothly, efficiently, and with minimal wear.

By sticking to a routine schedule, you prolong the life of your vehicle and ensure it continues to perform at its best. 

The significance of regular oil changes for your vehicle is far-reaching.

Engine Lubrication

Oil circulates throughout the engine, especially the pistons, ensuring all moving parts are adequately lubricated. This lubrication is essential to minimize friction between components, preventing wear and tear. 

Over time, oil breaks down and becomes less effective, making regular oil changes crucial to maintaining optimal engine performance. If you don’t change your oil, the pistons will warp, and the engine will become completely useless.

Heat Regulation

Engines heat up when they operate. Oil plays a crucial role in regulating this heat. As oil circulates, it absorbs heat from various engine components, helping to keep temperatures within a safe range. 

Fresh, clean oil is more effective at regulating heat better, ensuring the engine doesn’t overheat or cause damage.

Contaminant Removal

Over time, dirt, debris, and contaminants can enter the engine. The oil and the oil filter trap these particles, preventing them from causing damage. Regular oil changes help ensure your engine is consistently protected from harmful debris.

Preventing Engine Wear

A well-lubricated engine experiences less friction between its moving parts. This contributes to smoother operation and reduces the risk of excessive wear on vital components. 

Optimizing Fuel Efficiency

Regular oil changes help maintain optimal engine performance, contributing to better fuel economy and saving you money at the pump.

Again, we highly recommend fully synthetic oil changes using GM’s OEM oil, dexos1. This oil meets the high standards set by the manufacturer for GMC and Buick engines.

Don’t Forget Tire Rotations

Don’t forget to have your tires rotated regularly to keep your GMC or Buick on the road for a long time.

Tire rotations are crucial for achieving even tread wear across all four tires. As you drive, each tire undergoes different levels of wear depending on its position on the vehicle and your drivetrain (FWD, RWD, or AWD).

Tires are a significant investment, and extending their lifespan is beneficial for your wallet and your safety. Routine tire rotations are a cost-effective preventive measure that contributes to maximizing the lifespan of your tires. 

Rotating the tires at regular intervals ensures that wear is distributed more evenly, extending the lifespan of the entire set. For example, you don’t get tire rotations, and your tires wear out at 40,000 miles. With the tire rotations, they would last 50,000 miles. Over the span of 200,000 miles, you would purchase five sets of tires at 40,000 miles per interval versus four sets of tires at the 50,000-mile interval. Considering a full set of tires can cost $500, that’s a significant savings. Plus, keeping your tires in top condition can prevent a host of other problems that can lead to big repair bills.
