Do MG HS cracked fuel caps affect fuel economy?

Some drivers believe that a poorly sealed cap may lead to fuel evaporation and mileage loss. Is there any evidence of lower fuel efficiency among Pakistani MG HS owners with this issue?

A poorly sealed fuel cap can lead to minor fuel evaporation, but most MG HS owners in Pakistan have not reported significant mileage loss. The impact on fuel economy is usually negligible, but prolonged evaporation can reduce efficiency slightly.
