Poor fuel efficiency in your Suzuki Alto can be caused by several factors that affect the engine’s ability to optimize fuel consumption:

Dirty Fuel Injectors: Clogged o r dirty fuel injectors can cause improper fuel atomization, leading to inefficient fuel combustion.
Clogged Air Filter: A dirty air filter restricts airflow to the engine, reducing its efficiency and increasing fuel consumption.
Faulty Oxygen Sensor: A malfunctioning oxygen sensor can send incorrect signals to the engine control unit ECU, causing the engine to burn more fuel than necessary.
Underinflated Tires: Low tire pressure increases rolling resistance, which in turn requires more fuel to move the vehicle.
Worn-out Spark Plugs: Worn o r fouled spark plugs can cause incomplete combustion, leading to poor fuel efficiency.
Excessive Idling o r Aggressive Driving: Idling for long periods o r driving aggressively with rapid acceleration and hard braking can also lower fuel efficiency.
Solution: Have your fuel injectors cleaned o r replaced if needed. Replace the air filter and oxygen sensor, if necessary. Check tire pressure and inflate them to the recommended level. Replace worn spark plugs, and practice efficient driving habits like avoiding prolonged idling and aggressive acceleration.
