Additionally, maintaining the engine's air-fuel mixture is essential. The air filter, located in the engine bay, filters out impurities and ensures a steady supply of clean air for combustion. A clogged or dirty air filter can restrict airflow, leading to reduced power and fuel efficiency. Regularly inspecting and replacing the air filter as recommended by the manufacturer can help maintain optimal combustion and fuel economy.

Other maintenance tasks that contribute to optimal combustion include checking and replacing spark plugs, ensuring proper fuel pump operation, and maintaining the engine's timing. Spark plugs play a critical role in igniting the air-fuel mixture, and worn-out or damaged plugs can result in misfires, reduced power, and increased fuel consumption. Regularly inspecting and replacing spark plugs at the recommended intervals can help ensure efficient combustion. Similarly, proper fuel pump maintenance and addressing any timing-related issues can further enhance engine performance and fuel efficiency.

Fuel Stabilizers: Additives can prevent fuel degradation, but their effectiveness varies by product

Fuel stabilizers are additives designed to extend the longevity of gasoline, diesel, or other fuels by preventing degradation and maintaining their quality over time. These additives can be particularly useful for vehicles that are stored for extended periods or for those that are used infrequently, as they help ensure the fuel remains viable and performs optimally when needed. The concept is simple: by inhibiting oxidation and other chemical reactions that can occur in fuel, stabilizers keep it in a more usable state.

However, it's important to note that the effectiveness of fuel stabilizers can vary significantly between different products. Some additives are highly potent and can provide long-lasting protection, while others may offer less benefit or even become ineffective over time.
