    1)mas matipid sa gaso pag laging full tank, me kinalaman daw sa pressure sa loob ng tanke kaya mas matipid.

    2)mas matipid sa gaso pag quarter-tank to half-tank full, the less weight the car carries.

    ano ba talaga?

    It is true...but it is so minimal or insignificant. I can do some calculations for you if you want.

    There are so many more ways of saving gasoline which have more significant effects, e.g. switching A/C, proper tire inflation, proper speed, smooth starting and stopping.

    Sst! Off-topic!

    Consider this.

    Your car weighs anywhere between 900 kilograms (small cars and old cars, like the "itlog" Lancer or LEC Sentra) to 1300 kilograms. Add maybe 10 kilograms of oil and water to that. If it's a big car, like an Accord, it'll weigh between 1400-1600 kilograms.

    If it's a truck, it's likely 1700 kgs to 2000+++.

    You personally weigh some 70 kilograms. Well, that depends... I weigh about 90 kgs... yes, I'm fat.

    Now... add the Fuel. Fuel weighs approximately 0.8 kgs to 1.1 kgs a liter. For simplicity's sake... let's put that at 1 kg per liter.

    So, a full tank on a car, approximately 55 liters, is about 55 kilograms. Half-a-tank is about 27.5 kgs. A quarter tank is 13.75 kgs.

    The difference between a quarter tank and a full tank is 41.25 kgs.

    Now, given your average 1.6 liter car and driver, with oil, will weigh about 1250 kilograms, that's a 3.3% difference in weight. While that matters in stop-and-go driving, and you can definitely feel the difference on the race-track, that small of a difference is miniscule in terms of fuel economy. Just pumping your tires harder or tuning up your car can make a bigger difference.

    And if you save anything by carrying less gas, it will be offset by the extra amount of fuel you burn to take that detour to the gas station, idling in line, then turning off the car and restarting it every time you go to the pumps.

    Personally, when I can afford it, I get a full tank. Keeping a good amount of fuel in the tank prevents water condensation from forming inside the tank and polluting the fuel. But if I can't afford it, I buy just 300-500 pesos of fuel. I don't notice a significant difference between either method, except I'm stopping more when I'm being cheap, and using more money buying snacks from the gas station.

    proper driving affects gas consumption significantly,and also your speed, like for example driving in just 80kph saves you about 30% of fuel than 120kph more or less. doesnt matter how much you have in your tank, that just my opinion.

    I think mas makakatipid ka kung sa pinaka murang gas station ka bibili ng gas na along your way. Pero para di abala sa akin, hanggang kaya, full tank ang binibili ko. Currently nasa 38.80 per liter ang unleaded dito sa shaw. nasa 40+ karamihan ng gasolinahan.

    Usually less than 1/4 ako kumakarga except kung week end ako mauubusan. pag nagkaganoon, fri ako kakarga.

    iyan ang madalas na misconception eh not realizing na mas makunsumo kung babayahi ka pa to gas station just to fill up.

    How about filling up on gas kapag early morning when the fuel is cooler and more condensed? Is this a proven way to "save" gas? Napansin ko lang kasi na parang masmagastos rin ang car ko sa gabi (siguronga kasi mascondensed ang fuel na binuburn)...

    Avoid traffic. Switch to a diff route or avoid peak hours.

    I agree, this is the best solution. Also do not speed. 80Km/hr is fast enough. No rapid accelerations nor decelerations.

    mas ok yata kung full tank na lang kung can afford naman para less trip sa gas station.. lalo na kung tulad namen na loyal sa isang gas station, petron.. ever since we bought the car, un na kasi ang gamet namen.. unless paubos na ung gas tapos wala talagang makitang petron.. kesa tirikan kami, pa-gas muna ng 100 sa ibang gas station..

mas matipid sa gaso...
