Do I use gas unnecessarily if I...?

Question:
...use the transmission to slow me down, instead of the brakes?
With my foot off the gas pedal, does the engine suck gasolene into the cylinders as the revs go up when I change down?

Answers:

I have a friend who is 18 and he wants to get his lisense asap but his permit expired, can he still go get it?

Depends on how old the car is. It will still suck gas if it has a carb. i think fuel injection gives the car the same amount gas as it would idling

Increasing the RPM's of an engine requires both more fuel and air whether you are accelerating or deccelerating.

Under a load, (acceleration) you will use more fuel that if you were slowing down by using the engine. It makes no difference if it a carbureted or fuel injected engine.

I just got my permit........?

of course...the amount of gas burned is proportional to the number of revolutions per minute (rpm) in a carb engine the fuel pump is run on a simple lever pump that runs off the rpms...an efi system uses a electric pulses to fire the injectors instead of a cable system(carb)
