Your Guide to 2020 GMC Sierra 1500 Scheduled Maintenance
When it comes to your GMC Sierra 1500, how you treat your car makes all the difference in its performance. If you put in the effort to keep up with proper maintenance, you could hit 200,000 miles (or beyond!) in your Sierra 1500. Not an expert in what services your car needs and when? No problem. Instead of waiting for an issue to arise with your Sierra 1500, you can stay ahead of problems before they even begin. Rely on the recommended maintenance schedule that’s been created just for your 2020 GMC Sierra 1500!
GMC knows your vehicle inside and out (they made it, after all!), so they’ve designed this schedule with your car’s unique needs in mind. Driving conditions, climate variations, and other variables can affect which scheduled maintenance services you’ll need; in most cases, though, recommended maintenance will consist of services like tire rotations, vital fluid checks/exchanges, filter changes, brake pad replacement, and oil changes. Keeping up with routine service appointments is a great way to keep your Sierra 1500 running for longer, decrease your risk of dangerous malfunctions on the road, and help you avoid expensive repairs caused by 2020 GMC Sierra 1500 problems later.
Essential Maintenance to Keep Your GMC Sierra 1500 Running Newer, Longer
Head to your nearest Firestone Complete Auto Care in your 2020 GMC Sierra 1500 for factory-recommended routine maintenance and an expert technician will begin by performing a Courtesy Check. This Courtesy Check can establish a baseline of what may need to be addressed during your service appointment. Every Courtesy Check will include a visual inspection of your Sierra 1500. We’ll check your head and tail lights, fluid levels, filters, tires (and their alignment!), and windshield wiper blades. We’ll also perform a free battery check to determine your battery’s charge level.
Could your 2020 GMC Sierra 1500 be ready for a new battery? In general, car batteries only last three to five years.

Talk to a Firestone Complete Auto Care technician to know when to change your oil. We'll also help you understand what type of oil to use for your 2020 GMC Sierra 1500.
