no.
you are totally wrong here.

i never saw any car under testing to have more than a quarter or half tankful!

passengers and luggage in car while testing??
no way!
passengers are seated in cars just to check the comfort level while the car is stationary.
and luggage is put in just to judge the capabilities of boot!

and cars are not tested to judge the worst case scenario. rather they are tested for best case scenario!
so that buyers can get the best possible informationabout the car.

As for me:

I always do full tank. Infact more than full tank. Fill up the tank preferably on a surface where my car is slightly tilted towards right. Shake shake shake, and fill to the brim

Always top up till the auto cutoff .. around 40 - 43 litres
Stick to one particular fuel station.
Drive till the needle touches empty, which seems to be around 10litres of reserve for the Baleno.

Duration between top ups - 16-19 days, 450+ kms.

Will it help FE if I try doing the top-ups after 200kms, taking into consideration the losses due to evaporation ?

OT, the fuel needle hits half-way mark at 325ish kms .. then drops the other half in the next 125-150 kms !

Car: M800

Always fuel my tank till the auto cutoff is reached. i fill whenever the fuel gauge is at 1/4. i burn the fuel in around 10-12 days time since travel is not much plus the 800 returns a good 16-17 in city and 19+ on highway.

Thanks for all your postings. Following are the facts which has come up in our discussion so far:

So far, from all your replies, it is for sure that filling up the tank to its fullness is the best practise.
1. It might add extra weight to the car but will also add in stability to the car.
2. This would prevent the metallic fuel tank from rusting due to water content in adulterated petrol we get now a days.
3. This would also help in reducing the fuel loss due to evaporation.
4. Also read somewhere that a full tank will keep the fuel injector pump cool, as it will have to work less.
5. Only risk with full tank is that the Car with full tank is more prone to damage by fire in case of accident.

Some other best practices:
1. Always refill when the climate is colder (early morning or late night).
2. Always opt for Auto Cut-off mechanism for refilling tank to FULL (good to measure the FE).
3. Always stick to the same Petrol Pump Station, once you are convinced.that they give better quality petrol.
4. When not using the car so much make sure that the fuel tank is atleast half tank and above (to prevent fuel loss due to evaporation and prevent rusting of metallic fuel tank).

Cheers!

@saurabasu: You sure have come to some funny conclusions!

Really?... How does more fuel slow down evaporation?

yes, Its the fuel pump .. which is inside the tank itself.

Where did this come from?... we have discussed this on another thread. Didn't draw a conclusion there but the discussion was sure in favour of "fill to the brim".

no.
this auto cut off is not a reliable thing to be assumed as something to measure a thing!
quite often it gets stopped on itws own even when tank is more than half empty!
it can't be assumed as a measure point to measure anything!

to calculate the fuel economy it is better to rely on your car's 'low-fuel-indication-lamp'.

Good to know that the post amuses you !!

Sorry for the confusion, now I rephrase it to moisture instead of water. Adulterated petrol is likely to have more moisture contents due to contamination.

More fuel in the tank means less the empty space, hence lesser evaporation (though this loss is very insignificant).

Please correct me if I am wrong.

Since we are also discussing the time of refuelling, I thought it prudent to give a reference to posts 115 and 116 of this thread.

I fill once in a week for Rs.1000/-. I really dont know that filling it during early morning and late in the nights has advantage. But mostly I fill during the late in the evenings while coming back from work. Sometime during the lunch break at 14.00 hrs. I normally dont go with such close calculations.
