@Lonely_Puma: If your car don't have CNG, I am afraid you can't drive with my technique. Yes one should be on petrol first before going to neutral. Car on CNG -> Shift it to Petrol -> Immediately Shift it to Neutral...You are done!
@autophile: Yes the engine will be runing. It is not possible with 'engine shut' as you mentioned. I wrote DON'T SWITCH OFF YOUR ENGINE. So the engine is not switched off.
@2c: It will not even consume water in the radiator. Offcourse it is great technique.
@cracked: the engine will never shut off. This is my brain where this amazing idea was generated.
@ALL: I will now explain it. Most senior drivers don't believe my this invention and the secret I revealed to them.
Energy can be produced from many things and we can transform energy from its one form to another. When we run car on plain road, the engine requires energy to run against gravity. Gasoline is burnt in combustion chamber and energy is produced which forces pistons and ultimately our car moves. If we cut-off fuel supply then car will stop, because the engine has no force left to go against gravity to produce motion.
On downslide why your car runs without pressing accelerator? This is because you are already going with the force of gravity which is not in the case when you are driving on plain surface. At this stage car pistons don't require fuel to produce force. You are already using gravity for moving the car. Here I introduce my amazing technique. Your car is initially on CNG when you start downsliding, turn your car on petrol and immediately turn it to neutral. You disengage fuel supply now. The engine will not shut down, it will keep working with the force produced by its own motion due to gravity. About gear shifting, you can drive car neutral, but it is very dangerous in car handling and braking. So it is advised to shift gears according to speed.
No one asked that how AC, brakes, power steering, headlamps, hi-end stereo component will work without fuel
Believe me this technique is not only for Bilal's Mehran. Come to me and I will prove my words and your car, headlamps, AC, Power Steering, power brakes, hi-end stereo component, all these things will be working without any fuel.
Bhai sab kuch tu aap ki garri ka chala dia hay muft mein, aub bhe yakeen na aiey tu chalao petrol par mujhay kia
