Do CNG cars get less mileage if you dont drive them often?

Hey does anyone know if its normal if a cng based car gives you significantly less mileage if you drive it fewer kilometers? or you barely use the car at all?

No.

It is dependent on Engine performance, Engine technical specifics (normal efi, vti etc), and many other stuff.. try this question on pakwheels, you will get a good reply..

Nope, it depends uopon the pressure at which your tank is filled, less the pressure, less the mileage and related probs.

But you must check air filter and keep clean and change if gone bad, so, millage will be good.
