The 2019-Present Mercedes GLB is compatible with unleaded gasoline with an octane rating of 91 or higher. For optimal performance, Mercedes-Benz recommends using premium unleaded fuel. Diesel variants, if available, require ultra-low sulfur diesel (ULSD). Always refer to the owner’s manual or fuel cap label for specific fuel requirements to avoid engine damage or reduced efficiency.

Q2

What are the maintenance requirements for the Mercedes GLB fuel system?

The Mercedes GLB requires regular fuel system maintenance, including fuel filter replacement every 30,000 miles or as specified in the owner’s manual. Inspect fuel lines and connections for leaks or wear during routine service. Use fuel system cleaners every 10,000 miles to prevent carbon buildup. Always follow the manufacturer’s maintenance schedule to ensure optimal performance and longevity.

Q3

How do I replace the fuel filter in the Mercedes GLB?

To replace the fuel filter in the Mercedes GLB, first, locate the filter, typically found near the fuel tank. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls. Disconnect the fuel lines and remove the old filter. Install the new filter, ensuring proper orientation, and reconnect the fuel lines. Restore fuel pressure by reinserting the fuse and checking for leaks.

Q4

What should I do if my Mercedes GLB has fuel delivery issues?

If your Mercedes GLB experiences fuel delivery issues, start by checking the fuel pump fuse and relay for functionality. Inspect the fuel lines for blockages or leaks. Test the fuel pressure using a gauge to ensure it meets specifications. If the issue persists, consider diagnosing the fuel pump, filter, or injectors for faults. Consult a certified technician for advanced diagnostics.

Q5

How can I optimize the fuel efficiency of my Mercedes GLB?

To optimize fuel efficiency, maintain proper tire pressure, use recommended fuel grades, and avoid excessive idling. Regular maintenance, such as air filter replacement and spark plug checks, is crucial. Drive smoothly, avoiding rapid acceleration and braking. Utilize eco-driving modes if available. Keeping the vehicle’s weight minimal and aerodynamic drag low also contributes to improved fuel economy.
