What can help prevent loss of engine power due to fuel issues?

1. Regular oil changes

2. Use of high-quality fuel

3. Installing a larger fuel tank

4. Increased tire pressure

The correct answer is: Use of high-quality fuel

Using high-quality fuel is crucial for maintaining engine performance and preventing loss of power due to fuel-related issues. High-quality fuel typically contains fewer impurities and is formulated to maintain optimal combustion efficiency. It also helps in reducing carbon deposits in the engine, which can impede performance over time. Additionally, high-quality fuels often contain additives that clean the fuel system, enhance combustion stability, and improve overall engine response. While regular maintenance like oil changes is important for overall engine health, it does not specifically address fuel quality or fuel system issues. A larger fuel tank increases capacity but does not affect the quality of the fuel being delivered to the engine. Increased tire pressure, while beneficial for tire performance and fuel efficiency, does not have a direct impact on engine power related to fuel quality. Thus, the choice of using high-quality fuel stands out as the primary method to mitigate problems related to engine power loss due to fuel issues.
