of the suggestions made, i would say the first one as the only logical one to practice.

definitely gonna try that.

of all the techniques, the only one i dont agree is that slow/ fast mode pumping. it doesnt make any different at all. the vapourisation happens inside the tank. so there is no question whether it will effect anykind of petrol pumped in.

one good thing the thread owner wrote is about the level of spaces in the tank that allows the liquid to vaporised. yes. it is true. the lower ur petrol in ur tank, the bigger space for petrol to vapour.

is that we must fill up the tank to full first, then only top up them for lets say 100km/50km journey?
well, thats sound stupid, is it?
