The Truth About Using Low Octane Fuel in Your Vehicle

TLDRUsing low octane fuel in your vehicle, especially in modern cars, can lead to engine damage and void the warranty. The octane number indicates the fuel's resistance to knock, and higher elevations require lower octane ratings. However, modern cars with electronic fuel injection and ignition timing control can compensate for higher elevations. It is best to follow the manufacturer's recommended fuel for your vehicle.
