Frequently Asked Questions

Why is an oil change important for a 2023 GMC Sierra 2500HD?

• Maintains performance: clean oil helps the engine deliver its rated power and torque consistently, especially under towing loads.
• Protects against deposits: regular oil changes prevent sludge and varnish that can impair fuel economy and responsiveness.

How often should you get an oil change for a 2023 GMC Sierra 2500HD?

• Follow the manual: the owner’s manual has the manufacturer-recommended interval—use it as your primary guide for scheduled maintenance.
