Yes, poor maintenance is a major factor in reduced fuel efficiency. Dirty o r clogged air filters restrict airflow to the engine, leading to inefficient combustion. Worn-out spark plugs and dirty fuel injectors can cause incomplete fuel burning. Neglecting timely oil changes results in higher engine friction. Regular servicing, including changing filters, spark plugs, and using recommended engine oil, helps maintain optimal fuel economy.
