Caring for your Buick, the right way

Engine oil is vital to your vehicle’s health, lubricating moving parts and reducing friction to help prevent engine wear. Over time, oil breaks down and collects contaminants, which is why regular changes are necessary. 
 
Recommended intervals: A general guideline for an oil change is every 7,500 miles. However, your Buick is equipped with an advanced Engine Oil Life System that provides a more accurate recommendation based on your specific driving habits and conditions. When the “CHANGE ENGINE OIL SOON” message appears, you should schedule service as soon as possible. The oil and filter must be changed at least once a year, even if the system does not indicate a change is needed. 
 
How to check oil: It’s a good practice to check your oil level regularly, especially before a long trip. Park on level ground and wait until the engine is cool. Remove the dipstick, wipe it clean, reinsert it fully, then remove it again to check the level. If it’s low, add the recommended oil. 
 
Choosing the right oil: Always use Buick-approved oil that meets the dexos1 specification and the proper SAE viscosity grade, such as ACDelco dexos1® Full Synthetic. You can find the specific requirements for your SUV in your Owner’s Manual or by consulting your dealer. For more details, visit the Buick Support engine oil page.

Your Buick relies on several essential fluids to operate correctly. Periodically checking these fluids is a core part of basic SUV maintenance. 

• Transmission Fluid: This fluid lubricates and cools the transmission. It is not typically necessary to check the level unless you notice a leak. 
• Brake Fluid: Proper brake fluid levels are critical for stopping power. If the Brake System Warning Light comes on, your fluid may be low, and the system should be inspected immediately. 
• Coolant: Also known as antifreeze, coolant prevents the engine from overheating. Check the level in the coolant reservoir and top it off if necessary with a 50/50 mix of DEX-COOL coolant and clean, drinkable water. 
• Windshield Washer Fluid: Keep the reservoir filled to ensure you can maintain clear visibility in all weather conditions.

 
For specific instructions and replacement schedules, it’s always best to consult your vehicle’s Owner’s Manual. You can find your manual on the Buick Manuals and Guides page. 

A vehicle’s battery typically lasts four to five years. Knowing the signs of a weak or failing battery can help you avoid being stranded. Dimming headlights, a slow engine crank or a warning light are all indicators. To extend your battery’s life, keep the terminals clean and free of corrosion. If you drive infrequently, consider removing the negative cable or connecting a trickle charger during extended storage. Learn more with our battery care guide.

Proper tire care is crucial for safety, fuel efficiency and ride comfort. A simple routine maintenance checklist for your tires should include regular inspections.

• Tire Rotation: Rotate your tires every 7,500 miles to promote even wear. 
• Tire Pressure and Tread Depth: Check pressure monthly when the tires are cold. You can check tread depth with a gauge or the penny test; if you can see all of Lincoln’s head, it’s time for new tires.
• Wheel Alignment and Balancing: While not needed on a regular basis, consider an alignment check if you notice unusual tire wear or your vehicle pulling to one side. If you feel vibrations, your wheels may need rebalancing.

Vehicle warranties typically cover defects in materials or workmanship from the factory. They do not usually cover the cost of routine maintenance items like oil changes, tire rotations or brake pad replacements. It is the owner’s responsibility to perform the required maintenance to keep the warranty valid.

Following a routine vehicle maintenance schedule is the best way to ensure your Buick SUV continues to provide the exceptional experience you deserve. By staying proactive with oil changes, fluid checks and tire care, you are helping to protect your vehicle for the years ahead. Be sure to familiarize yourself with your vehicle’s warning lights, and consult your Owner’s Manual for specific information.
