What grade of fuel does the Focus use?

[OMargaret]

For the Ford Focus, please use unleaded gasoline that meets the GB17930-2013 standard, specifically 93-octane (IV) or higher, or 92-octane (V) or higher. Here are some important notes: 1. Only use high-quality fuel without additives or other engine protectants. 2. Do not use fuel containing methanol. 3. Avoid running out of fuel, as it is harmful to the powertrain components. If the vehicle runs out of fuel, after refueling, you need to repeatedly turn the ignition switch on and off several times to allow fuel to be drawn from the tank into the engine. When restarting, the starting time will be a few seconds longer than usual. For keyless start vehicles, you can directly start the engine, but the starting time will also be longer than normal.
