A question on the octanes

<< < (4/4)

scoobydoo:
no problem at all, can fill in as much as your tank can contain.

have you seen drivers "shake" their car after the trigger full activated stop? especially so when at JB petrol kiosks or when a big discount is given.

when we activate the pump trigger, pressurised petrol is "shot" into the tank causing lots of bubbles inside the tank. air bubbles take up space and level rises faster than actual volume occupied by petrol. thus when the trigger automatically stops (a built-in safety feature to prevent overflow), the tank is not actually full. by shaking the car, those drivers hope to rid the trapped air and make space for more petrol.

personally, i don't do that as the difference is not substantial enough to warrant such less than graceful act  ;)
you may want to try topping up your tank to full at intervals instead of one "blast". try releasing the trigger for a few seconds after every 10~15L to allow bubbles to escape, slow down the fill rate by controlling the trigger level for the final few litres and you may likely obtain the same effect of shaking the car to maximise intake. takes a bit more time but definitely looks more graceful  :w00t:
