Why does my Suzuki Swift consume more fuel after crossing 80,000 km?

After clocking over 80,000 km, my Suzuki Swift’s mileage has decreased noticeably. What engine o r system components typically wear out around this time that could lead to higher fuel consumption?

At around 80,000 km, key engine components such as oxygen sensors, fuel injectors, and throttle body can start to wear o r get dirty. These affect how the engine mixes air and fuel, which leads to poor combustion and higher fuel usage.

Likely Causes:

Clogged fuel injectors leading to uneven fuel spray.

Dirty throttle body o r idle control valve.

Failing O2 sensor, which sends incorrect signals to the ECU.

Worn timing components reducing engine efficiency.

Fixes:

Get a full engine scan and inspection.

Clean o r replace O2 sensor and injectors.

Consider a throttle body service.

Use high-quality synthetic oil and fuel system cleaners periodically.
