What Are the Most Common Reasons for Poor Fuel Efficiency in a Suzuki Alto Lapin?

Poor fuel efficiency is a common concern, and several factors can cause this in the Suzuki Alto Lapin:

Worn Spark Plugs: Faulty o r worn spark plugs can cause incomplete combustion, which wastes fuel. Replacing spark plugs can improve engine efficiency.
Dirty Air Filter: A clogged air filter can restrict airflow into the engine, leading to poor combustion and reduced fuel efficiency. Regularly replacing the air filter helps keep the engine running optimally.
Low Tire Pressure: If the tires are underinflated, it increases rolling resistance, which makes the engine work harder and consumes more fuel. Always check tire pressure regularly and keep them properly inflated.
Fuel System Issues: Dirty o r clogged fuel injectors can cause poor fuel atomization, leading to inefficient fuel usage. Getting the injectors cleaned o r replaced can restore fuel efficiency.
Incorrect Driving Habits: Aggressive driving, frequent idling, and speeding can significantly reduce fuel efficiency. Try to maintain a steady speed and avoid excessive acceleration.
Overloaded Car: Carrying excessive weight, especially in a small car like the Alto Lapin, can reduce fuel efficiency. Remove unnecessary items from the car to improve fuel economy.
Engine Oil Quality: Using the wrong grade of engine oil o r old oil can affect fuel efficiency. Ensure the oil is clean and of the correct grade as specified by the manufacturer.
Solution:

Replace spark plugs if they are worn o r damaged.
Change the air filter if it’s dirty.
Keep tires inflated to the correct pressure.
Clean o r replace clogged fuel injectors.
Adopt better driving habits to conserve fuel.
Use high-quality engine oil and replace it regularly.
