Do you "shake" your car when you get a full tank?

Wala akong makitang thread dito...

Do you "shake" your car when you get a full tank? Please explain why.

Mods, kung mali po ng forum paki lipat na lang. Tnx!

nope, the vibrations caused by driving your car normally will let the fuel level out as well as make your gauge gradually increase after a few seconds.

another automotive myth...

Myth 4: Shake car to maximise fuel capacity

YOU may have seen people rocking their cars from side to side while pumping petrol, especially where prices are discounted.

The idea is to shake out all the air bubbles to maximise the amount of cheap petrol they pump. They also continue filling even after the pump automatically cuts off, squeezing in every last drop they can.

Don't expect to save much this way.

'These air gaps, if any, are not large,' said the AA spokesman.

'The savings, if any, is negligible.'

In fact, trying to fill the tank right to the brim may be dangerous.

'They should avoid filling it right to the top because the petrol can spill out, posing a safety hazard,' said Kah Motor's Mr Ng.

nope, kasi liquid ang fuel so basically it "knows' where to go...

nope. tingin ko ginagawa yan ng mga mayroong defective fuel gauges. yinayanig para yung floater tumama ng lutang.....

nakakadagdag din ako ng almost 1 liter after auto cut-off ng pump by shaking. almost negligible nga compared to the tank capacity of 92 liters.

nasabi na lahat ng post ni mazdamazda pero ginagawa ko ito noon to get the bubbles out of the tank para mas accurate ang pagkuha/pagcompute ko ng fuel economy ng sasakyan ko...for fuel economy computation purposes lang...pag puno na kasi di na kaya ng "breather" kaya kapag kinalog mo masisiksik mo pa ito dahil madidisplace yung hangin na natitira pa sa fuel tank...pinupuno ko ng gasolina hanggang labi ng butas...tulad ng post ni mazdamazda, huwag nyong gagawin ito(pagsasagad hanggang labi) dahil delikado ...

Dont you create more air pockets by shaking the car? Its basic physics that the more disturbance you create on a water surface the more air pockets will develop.

If shaking has ANY logic to it, I'd think that race cars or high end cars will have a built-in tank shaker whenever a car is refueled. Doesn't make any sense.

so this is a useless exercise pala, have to remember to not fill the tank to the brim next time

**chieffy** · January 3rd, 2005 11:06 AM

based on my experience as gasoline boy...bababa pa talaga level ng fuel sa butas kapag kinalog mo dahil lalabas pa yung hangin na "naipit" somewhere sa uneven top/upper portion ng fuel tank...fuel tank na di even ang space/shape ng top portion...

guys magkarga or mag obserba kayo paminsan minsan kapag magrerefuel para malaman nyo kung totoo o hinde...
