Why is Higher Octane Gas Important?
Understanding the right fuel for your GMC truck is key to keeping it running smoothly and efficiently. Premium gas isn’t just a luxury; it’s a necessity for certain models. When you’re driving a high-performance truck, like the Sierra 1500 or Canyon, using the correct fuel ensures your engine operates at its best.

For models that require premium fuel, such as those with the 6.2-liter V8, it’s best to stick to the recommended fuel. The GMC premium fuel requirement is in place to ensure that your truck runs at its best, saving you money in the long run and preventing costly repairs. Whether you drive a Sierra 1500 or Canyon, following these fuel recommendations will keep your truck performing at its peak.
Which GMC Trucks Don’t Need Premium Gas?
Not all GMC trucks require premium gas. In fact, there are several engine options available that run perfectly fine with regular gasoline.
