2014–2018 GMC Sierra 1500 Oil Changes

Routine oil changes are one of the most important ways to protect your Sierra’s engine. Fresh oil keeps engine components lubricated, reduces internal wear, and helps prevent overheating and sludge buildup, which is especially critical if you tow heavy loads or drive in extreme conditions.

Third-gen Sierra 1500 models come equipped with an Engine Oil Life System, which monitors your driving habits and notifies you when it’s time for an oil change with a “CHANGE ENGINE OIL SOON” message. When this message is displayed, have your oil changed within the next 600 miles. Regardless of whether this message appears, you’ll need to get an oil change at least once a year.

For dependable performance and long-term durability, don’t skip your oil change. Schedule yours at Firestone Complete Auto Care and keep your engine running strong.

2014–2018 GMC Sierra 1500 Tire Maintenance & Info

Tire maintenance plays a huge role in safety, handling, and fuel economy. To ensure even tread wear and longer tire life, rotate your tires every 7,500 miles. Watch for signs of wear like cracking, vibrations, or tread depth below 2/32 inches—these indicate it's time for a new set of tires.

Always check your tire placard or consult a tire expert to confirm the best size for your trim, as sizes can differ depending on vehicle options.
