Buick and GMC maintenance schedule explained
Oil-life monitors, severe service, and which jobs are time-based instead of mileage-based.
GM oil-life systems are mileage-and-duty aware. Severe service — short trips, dust, towing — shortens intervals. Cabin filters, brake fluid, and some drive-unit services are still time-based. We print the next due items after every visit.
