How to Reduce Fuel Consumption of Buick Excelle?

[Angelo]

Here are some methods to reduce fuel consumption for Buick Excelle: 1. Maintain the air filter: Dirty fuel or obstructed airflow can easily increase fuel consumption. The air filter's function is to purify the air entering the cylinders. If the fuel exceeds standards or is too dirty, it can obstruct airflow, leading to increased fuel consumption. Tests have shown that excessively dirty fuel or an overfilled fuel level can increase consumption by more than 20%. Therefore, regular maintenance is essential. After each cleaning, apply a certain oil film, and the lubricating oil at the bottom should also be filled according to the marked standards. 2. Regularly remove carbon deposits: Excessive carbon deposits can increase fuel consumption by about 8%. When carbon deposits accumulate in the combustion chamber, it can easily cause spontaneous ignition of the combustible mixture, leading to a drop in power. If carbon deposits are excessive, fuel consumption can increase by about 8%. Therefore, during secondary maintenance or when the cylinder head is disassembled for other reasons, carefully clean the carbon deposits in the combustion chamber and on the piston top to reduce unnecessary fuel consumption. 3. Check the spark plugs: If one spark plug is not working, fuel consumption can increase by 25%. The spark plug introduces high-voltage electricity into the engine's cylinders, generating a spark between the electrodes to ignite the mixture. Tests have shown that if one spark plug is not working, fuel consumption can increase by 25%. Additionally, factors such as the spark plug gap size and the amount of carbon deposits directly affect power and fuel consumption. During use, ensure the spark plug gap is correctly adjusted.
