Our Ultimate 2026 Genesis Gas Guide: Mileage & Fuel Type
From sculpted sedans to performance-focused SUVs, every 2026 Genesis gas-powered vehicle is engineered to deliver smooth, responsive power. But to make the most of that twin-turbo growl or silky 4-cylinder efficiency? You’ll want to fuel it right. That’s why we’ve created this go-to gas guide—to help Columbus drivers know exactly what each model needs, and how many miles you can expect between stops.
Why Use Premium Unleaded in Your Genesis?
If you’ve invested in a Genesis, you’ve invested in performance. Most 2026 gas-powered Genesis vehicles are turbocharged, and that means they thrive on 91-octane premium unleaded. It’s how you protect your engine and maximize your MPG.
Putting in lower-octane fuel? You can in some cases, but you’ll lose performance and efficiency—and over time, it might lead to more wear and tear than you bargained for. When the badge says Genesis, premium fuel is part of the experience.
