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

[the_wildthing]

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!

[ssaloon]

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...

[chieffy]

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 ...

[theveed]

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.

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

[ram]

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.

[BlueBimmer]

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

[chieffy]

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...

[Alfalfameister]

Shaking the car may make you fill the car to the BRIM... so in that sense, it does work. But the bigger question is, WHY? So you can add maybe two more liters?

In any case, filling the car to the brim is NOT good -- baka may matapon pa. When you accelerate, baka may matapon.

Finally, AYOKO MAG MUKHANG TSUPER NG JEEPNEY... or Taxi... heheh...

[aann]

may naiipit ba na hangin? dba liquids "find their way" through any container, and d rin naman malapot ang gasolina. bka naaayos lng yng floater pgka-shake.

[pajerokid]

To answer the initial question.... NO.

But i agree with most of the guys here.... the more pertinent question should be why?

[chieffy]

aann, imagine an inverted funnel...kung ganun ang shape ng fuel tank natin maari pang lumabas lahat ng hangin habang nagpupuno ka ng fuel pero di ganun ang shape ng fuel tank natin...nasubukan mo na bang magbaklas ng isa? merong uneven portion fuel tank at doon naiiwan or "naiipit" yun hangin na hindi makakapunta sa butas unless kalugin mo yung sasakyan...ang hangin sa fuel tank eh palabas lang naman ang daan kaya wala nang air pocket na maidadagdag sa pagkalog niyan...

anyway di naman talaga kailangan gawin ito...in my case, ginagawa ko ito noon dahil gusto kong sisiksikin ng fuel ang tanke ko dahil gustong kong maging mas accurate ang pag COMPUTE ko ng fuel economy by eliminating all the air in my fuel tank...

Kuya chieffy..tama ung sinabi mo. Pero nalalabuan ako sa paraan ng pag compute mo.

Diba magiging mas accurate kung ididivide mo ang liters of gasoline by the kilometers na tinakbo.

km per liter = kilometer/liter

Basta magpagas ka pag ubos na ung laman ng tangke or pag umilaw na ung low fuel warning light. Ganun kasi ung ginagawa ko eh.

akala ko kaya inaalog ng mga jeepney drivers yung jeep nila pag nag-fill up eh inaaliw nila yung mga pasaherong na-bored habang nag-full tank siya. minsan nga may kasakay ako sa jeep na chick na maganda ang hinaharap, tapos inalog nung driver yung jeep, ayun hawak agad yung chick sa harap nya kasi umaalog din. lalo naman ginanahan yung jeepney driver na alugin yung jeep. sige alog ng alog, todo talaga ang galing! at hawak pa din yung chick sa harap nya! di na yata nakapag-pigil yung isang mama na katabi nung chick sinigawan yung driver, "pare tama na lumabas na!" tingin kami lahat sa kanya, tapos yung chick sasampalin na sana sya! napansin ng loko kaya dalidalian nyan sinabi "yung hangin sa tank mo!"

Ok kwento mo sir yebo... natawa talaga ko dun.

[pajerokid]

hahaha!!! True story ba yan yebo?!

[xam]

SIR YEBO,ang kulit po nang kwento!!! haha!!

filling up my car upto the brim of its tank gave me an extra 50 kilometers of travel, now that's kind of convenient because it's a hassle for me going back and forth to gas stations, i really like to maximize my cars tank, but now i'l remember not to give my car a full tank up to the brim...

[BlueBimmer]

haha nice perverted jeepney driver!
