Fuel Consumption

**NvM** · 20-06-2007 02:04 PM

i get a fuel economy ranging for 5.7-6.5, car is running on 17's with BBK & turbo

& i've checked the range i get out of a tank & done the maths the fuel economy checker isnt screwed up

I got my fuel economy down to 5.6/100km. But that only happens after long trips. It slowly goes up as I do short trips to pick up people from nearby etc.

Love fuel consumption while cruising on the highway 8)

5.6?! what the hell..
my 'normal' drivin gets like 8.3L/100km..

prob cause u do alot of stop start driving. i know at least for me i just hit the highway & cruise at 80 all the way there

Yeh when I first got my car it was at 10/100km because all the trips i did were jsut 1km trips where there were heaps of stops.

i go on the m5 east alot..
yeah i guess the traffic to uni sucks, and i always have a habit of warming the car up before i go anywhere.
i still believe its quite high compared to other people

lol dude, are u running on 2nd gear on m5 or something?
I assume you're going to UNSW

Even with peak hr traffic, i only get 7.3 max.
But otherwise, 6.2 on average

My best record would be 5.2L with ultra granny driving. But it's really no point since it really inaccurate

180km a tank for my rx7.... (60lt) 500km+ for my civic (45lt tank)

PULP on both

My new jazz is throwing up really high consumption. I have ran 450km so far and my fuel tank is now empty. So it is actually using slightly more than 10L/100km! I can't see how I can get it down to 7L/100km...oh, and I am using BP Ultimate.

whats the best way to calculate the fuel consumption (L/100km) for a vehicle which doesnt have the trip computer?

i've been told to use this formula: litres filled into tank (ie. 39L) / mileage (ie. 450km) x 100 = 8.6

lol...is this the correct way?

Well, the computer on my Jazz was recording between 7L to 10L. But I did my own calculation. I pumped up full tank with BP Ultimate on my Jazz and took note of the mileage. Drove happily till yellow signal came up...drove for another 25km with yellow signal on and took my calculations from there. So I have clocked 450km since I last fuel and divide that by 42 litres (full cap for VTI Jazz) and I got my L/KM.
