What are the solutions for high fuel consumption in the old Excelle?

If damaged, it will reduce ignition energy, causing uneven combustion of the air-fuel mixture, leading to slower acceleration and increased fuel consumption. Spark plugs should be replaced on time. Damaged tires can easily affect driving safety. When tire pressure is below standard, it increases rolling resistance, which not only accelerates wear but also raises fuel consumption. Check the wear level of the tires. Severe wear reduces friction, which can also lead to higher fuel consumption. Excessive engine carbon buildup is a significant cause, mainly due to the use of unsuitable fuel. It is recommended to add a certain amount of cleaning agent when refueling.
With years of experience in car repair, I frequently deal with fuel consumption issues in old Excelle models, which are often caused by engine carbon buildup or aging fuel systems. I recommend first checking the air filter; if it's too dirty and blocks the air intake, the engine has to work harder, naturally burning more fuel. Next, inspect the spark plugs. Old spark plugs with inaccurate ignition should be replaced with new ones to save fuel. Also, pay attention to tire pressure; insufficient inflation increases rolling resistance, wasting fuel unnecessarily. Driving habits should be adjusted—avoid frequent hard acceleration and braking. In city traffic, try taking detours or combining trips. If maintenance records are unclear, it's best to visit a professional shop for a thorough cleaning of the fuel injectors and catalytic converter, as these parts are prone to clogging in older cars. Regular oil and filter changes are also essential; thick oil increases friction and affects fuel consumption. In short, start with simple checks and troubleshoot step by step—it's cost-effective and efficient.
