Consequences of Running a Gasoline-Powered Vehicle on Empty in Spain

As the new year begins, many expats in Spain might be unaware of the potential consequences of running their gasoline-powered vehicles on empty. This common mistake can have significant impacts on both the vehicle and the environment, especially in the context of Spain's evolving energy landscape.

Vehicle Damage

Running a vehicle on empty can lead to serious damage to the fuel system. When the fuel level drops too low, the fuel pump, which is usually submerged in fuel, can overheat and fail. This is because fuel acts as a coolant for the pump. Additionally, debris and sediment at the bottom of the fuel tank can be sucked into the fuel system, causing clogs and further damage to the engine and fuel injectors.

Environmental Impact

In a country committed to reducing its carbon footprint, such as Spain, the environmental implications of vehicle maintenance are crucial. Spain has recently confirmed its coal phase-out by 2025 and is actively promoting sustainable fuels, such as Sustainable Aviation Fuel (SAF) and hydrotreated vegetable oil (HVO)[3][4].

For instance, companies like Moeve are pioneering the use of SAF, which can reduce CO2 emissions by up to 90% compared to traditional kerosene. This initiative aligns with Spain's broader commitment to sustainability, including the European 'ReFuelEU Aviation’ mandate that sets a minimum of 2% SAF usage starting January 1, 2025[2].

Economic Considerations

The economic costs of neglecting vehicle maintenance can be substantial. Repairing or replacing a damaged fuel pump and cleaning the fuel system can be expensive. Moreover, with the rising demand for renewable fuels and the imposition of EU anti-dumping duties on imported biodiesel and HVO, the cost of fuel and maintenance is likely to increase[4].

Energy Efficiency and Policy

The International Energy Agency (IEA) has highlighted the importance of energy efficiency in reducing energy costs and lowering emissions. The upcoming IEA’s 10th Annual Global Conference on Energy Efficiency in Brussels, co-hosted with the European Commission, will focus on accelerating improvements in energy efficiency, a critical aspect of Spain's and the EU's decarbonization strategies[5].

Practical Advice for Expats

Given these considerations, expats in Spain should be mindful of their vehicle's fuel levels to avoid unnecessary damage. Here are some practical tips:

• Regularly Check Fuel Levels: Ensure your vehicle's fuel tank is not allowed to drop below a quarter full.
• Use High-Quality Fuel: Opt for fuel from reputable sources to minimize the risk of debris and contaminants.
• Maintain Your Vehicle: Regular maintenance checks can help identify potential issues before they become major problems.
• Consider Sustainable Options: As Spain moves towards more sustainable energy solutions, consider the long-term benefits of transitioning to vehicles that use renewable fuels.

By being aware of these factors, expats in Spain can contribute to a more sustainable and environmentally conscious driving culture, aligning with the country's broader energy and environmental goals.
