partypest, I dont think this is a good practice of bringing in neutral at higher speeds, Pls dont do it again....You will be saving fuel is absolutely a myth but u r definitely loosing out of your control of not engaging your engine control into braking or slowing down....Your engine should control your car and not your brakes...
Infact when u r in 5th gear doing higher speeds(say 100kmph) and remove ur foot of the accelerator, ur fuel is cutoff automatically (in MPFI engines) and engine braking mechanism makes sure that you are not out of control...U will achieve some unbelievable FE by the following practice...
say at 100kmph/5th gear u remove ur foot, let engine braking decrease the speed to 70-80kmph then u again put foot on the pedal and increase the speed to 100kmph and remove the foot again....and continue doing this process...
