The Suzuki SX4—produced between 2007 and 2013—earned a solid reputation for reliability, practicality, and efficiency. To help owners and enthusiasts get precise information about its fuel system, we’ve compiled a comprehensive breakdown of the SX4 fuel tank capacities, including differences between body styles, engine options, and drive configurations.

🔧 Overview of Suzuki SX4 Fuel Tank Sizes

Across all model years and trims, the Suzuki SX4’s fuel tank capacity remains consistent at 50 liters (13.2 U.S. gallons). This provides a balanced range suitable for city and highway driving, especially when paired with its efficient 2.0L engine.

🧭 Driving Range Estimates

The actual driving range depends on your SX4’s fuel economy, which varies slightly by drivetrain and transmission.

Tip: Always refuel when your gauge shows 1/4 tank remaining to protect the fuel pump and ensure consistent performance.

⛽ Fuel Type Recommendations

• Recommended Fuel: Regular Unleaded (87 Octane)
• Fuel Tank Material: Steel (anti-corrosion coated)
• Fuel Filler Location: Left-hand side (driver’s side)

Although some markets offered 95-octane fuel recommendations, regular unleaded gasoline is entirely suitable for all North American SX4 models.

🚗 Fuel Economy and Efficiency Factors

Several elements influence the SX4’s fuel efficiency:

1. Driving Style: Smooth acceleration and maintaining steady speeds improve fuel economy.
2. Tire Pressure: Underinflated tires can increase fuel consumption by up to 3%.
3. Cargo Load: Avoid unnecessary weight in the trunk or roof racks.
4. Maintenance: Clean air filters, proper oil viscosity, and regular fuel system checks sustain efficiency.

⚙️ How to Check Fuel Level Accuracy

If your fuel gauge displays inconsistent readings, the issue could be linked to the fuel level sending unit inside the tank. This component uses a float and resistor to measure fuel level. Over time, wear or contamination can lead to incorrect readings.

Common Symptoms:

• Gauge stuck on “Full” or “Empty”
• Fluctuating fuel level display
• Check Engine Light (P0460–P0464 codes)

🧰 Fuel Tank Replacement and Maintenance Tips

If you ever need to replace or service the tank:

1. Relieve fuel pressure by removing the fuel pump relay and starting the engine until it stalls.
2. Disconnect the battery to avoid electrical hazards.
3. Use jack stands when accessing the tank from underneath.
4. Drain all fuel before removing the tank to reduce weight.
5. Inspect hoses and EVAP lines for cracks or leaks before reinstallation.

Always use OEM-grade replacement tanks or high-quality aftermarket equivalents to maintain emission compliance and safety standards.
