Why your mileage may be lower than the brochure

Test conditions ≠ real life

Manufacturer figures are tested in lab conditions. Real-world mileage in city traffic is typically 20–30% lower.

AC takes 5–15%

Running the AC at full blast can cut fuel efficiency by up to 15% — more in stop-and-go traffic.

Service is the cheapest fix

A timely engine service, clean air filter, and fresh spark plugs typically recover 5–10% of lost mileage.
