What is your Actual Fuel Efficiency?

Gansan · 28th July 2010, 09:35

I too top up my tank regularly after auto cut off, and I have noticed an interesting thing. The amount of petrol it takes to bring the level to the brim (after auto cut off) varies from 0.75 to 1.75 litres approx, even with the same pump/nozzle. Even after filling to the brim, if you wait long enough, the level still goes down. So I am beginning to wonder whether I should test it by the auto cut off method a few times.

In Mysore, we used to get 14-15 kmpl from our Maruti 800 4spd 2001, under city conditions. In Bangalore, we get just 11-11.5 kmpl.

Bangalore traffic is so pathetic that there is so much difference.

@Gansan: The logic is simple - the amount to top-up varies because auto-cut off can happen anywhere in that range. Auto-cut off does not happen consistently at one fixed point - it varies from nozzle to nozzle and even how far the nozzle is inserted. Top up will be more accurate in any case.

And you see the fuel level going down a bit mostly because the extra fuel that fills the pipe overflows a bit. It can also happen when the air bubbles that went inside the pipe/tank along with fuel comes up and and escapes.

PS: Top-up is not a recommended way of filling the tank - I do it only to test FE.

EDIT: In my new car (Punto) I don't have to do this ever, as the MID shows the FE always.

MID shows average speed of 22 kmph.

Agreed! I top up only before I go on highway trips and also immediately after I return, to check the mileage. At other times I will fill a flat 10 litres when I see the fuel level is at or below the half tank mark.

I hardly ever check my city average as I use the car mostly during weekends. Instead I just knock off 6 KM from my highway mileage figure to arrive at the approximate city average, which should be a safe bet!

I have driven my new ANHC-VMT now for over 2000 KM's and I had consistanly got the FE over or around 15/lit (Calculated by Tankfull -TankFull method).
When its 50% city + 50% bypass road (can't really call it Highway + Hinjewadi traffic) I get 17+ /lit.
When its 80% city + 20% bypass road I get 15+/ lit.

Every car of mine has been filled to the brim for every fill, all these years.

Linea / Punto MID figures are reported quite accurate. Can't say that about the Manza though as it has variations.

My Punto mjd, under bangalore traffic conditions+highway runs : 18.2 km per litre

VeluM · 28th July 2010, 19:02

Checked the City FE of my 2008 Chevy Spark. Stock tyres, 100% City, 100% AC (Yeah, I know it is Bangalore, but its to avoid pollution and keep the interiors clean) :P

Worked out to 13.249kmpl. Not bad, but used to be better. The clutch definitely needs to be replaced, will get that done early August and check again.

Not bad, considering Bangalore traffic.

My dad could extract 24 Kmpl from Punto MJD on a highway (well not exactly higway - busy NH47) drive of about 110 Kms.

On highway with 100% AC on, and even at higher speeds it gives me about 14.2 KMPL.

Mine is ANHC Automatic with wider tyres (195/60R15) and in 100% Faridabad with 100% AC on i am getting 10.5 KMPL.

Just visited the Faridabad - Mathura - Bharatpur - Fatehpur Sikri - Agra - Faridabad (375KM) and it gave 16+KMPL.

Anyone who owns the new Wagon-R 1.0, please post the FE figures. I want to compare it with that of Spark and see the difference.

TIA.

I am driving a Hyundai Sonata, the new one, and it is returning me 20 mpg,thats what the reading tells me. Its a beautiful car.

echo77 · 31st July 2010, 02:39

Wifey continues to break WagonR (2005) mileage records with her sedate driving. First time it has reached 18 km/l.

Last tank2tank: 529km / 29.34l = 18.03km/l
Petrol used: IndianOil XtraPremium
