Every 15,000 miles in your Buick, it's best to have the tires rotated, engine oil and filter changed, and windshield wipers replaced. This should be accompanied by inspections of various systems such as the engine cooling system and your tires.

In addition to services found in the 15,000-mile interval, every 22,500 miles we'll check the condition of your engine and cabin air filters and can replace them if needed.

At 45,000 miles, along with the services mentioned above, your vehicle should have all fuel and vapor lines and hoses inspected for damage or other problems and your automatic transmission fluid replaced.

The major 75,000-mile interval includes more extensive services such as rear axle fluid replacement on all-wheel-drive models.

When your Buick gets closer to 100,000 miles on the odometer, it's time to replace the spark plugs and other services mentioned above to keep it running smoothly for another 100,000 miles.

During this major service interval, the 150,000-mile recommended maintenance is to inspect and replace your engine's accessory belts as they begin to reach the end of their life expectancy.
