gurgled happily, sounding much like they were saying:

I am a person who only knows how to drive vehicles not what goes on
under the bonnet can any one tell me why or what causes a car or any
other vehicle fitted with aircon use more fuel when the aircon is in
use ? . I only came by this information today otherwise I would not have
been giving the aircon in the new car so much stick this week , no
mention in the handbook regarding the aircon using fuel !.

The compressor for the aircon doesn't just spin round on it's own. It's
belt-driven from the engine, and requires effort to turn it. That effort
puts extra load on the engine, which requires fuel.

OTOH, NOT using the aircon is the best way to make sure it doesn't work.
The seals dry out, and the gas escapes.
