actually our mechanics are tuned to the Law of Jutt (jet) , all their life they have been countering and altering and manipulation different Jutts to get the desired result, be it from Maula Jutt to Jumbo Jutt...
so the mind is locked at the pinnacle of jutt and whenever a fuel related problem is presented to them the solution is to use Chota ya Bara Jutt...
now comes new era and an afterburner is added to jutt and inJUTTker emerges, so now fuel problem is resolved using injuttker from different things countries and universes...but the rule of thumb is same...Chota injuttker ya Bara injuttker
