Why is my Suzuki Wagon R giving poor fuel average in city traffic conditions?

I own a 2021 Suzuki Wagon R VXL, and I’ve noticed that the fuel average in city traffic has ped to around 10–11 km/l, even though the company claims 17–20 km/l. I mostly drive in Karachi with AC on. I’ve recently done engine oil change and tuning, but there’s no improvement. What could be the main reason for this poor mileage in urban conditions? Could it be related to the throttle body, plugs, o r driving style?

Fuel economy in dense Pakistani city traffic like Karachi o r Lahore often suffers due to:

Frequent stop-and-go driving

Use of AC

Low RPM idling

Short-distance trips where the engine doesn’t reach optimal temperature

Even if you’ve recently done tuning, the following might still affect fuel economy:

Dirty throttle body o r idle sensor

Weak spark plugs o r incorrect spark plug gap

Clogged air filter o r low-quality fuel

Engine running rich due to faulty sensors like MAF o r O2 sensor

What You Can Do:

Clean throttle body and check idle RPM

Replace o r inspect spark plugs and air filter

Ensure tire pressure is 30–32 PSI cold

Use high-octane fuel occasionally to clean internals
