GasBuddy currently offers the ability to view/report prices for the three main grades of gasoline; Regular (85-87 Octane), Mid-Grade (89 Octane), Premium (91-93 Octane), E-85, Unl88, and Diesel.
We are working on adding other fuel types and sources to the website and apps in the future. Some fuel types are only available in certain markets. Stay tuned for upcoming changes!
