Fuel Economy - What do you get out of a tank? (3rd gens only)

[doddski]

i been playing around with excell spreadsheets and the like for my fuel economy,
i get it to work out based on actual and T/c average /100km fuel usage a projected range i could get out of a tank.

These figures i came up with over a combined cycle of city and highway style driving per tank - cant give you ratios... they are 'combined figures' as to me they represent a more real value of how much fuel i use

AVERAGE range: 663.45km - based on a full 71L tank

Worst range: 613.07km (based on a fuel average of 11.2L/100km)

BEST projected range: 729.14km (with a fuel average of 9.74L/100km - calculated, T/C said 10.0L/100km)

when i fill up the tank, i always reset the meters, and each time i fill it up, the DTE is telling me 600km+ till empty estimated.

My funky lil excell spread sheet tells me also, that the worse fuel econ figure iv gotten, is 11.2L/100km (11.58L actual), and the best ever of 10.0L/100km (9.74L actual)

i dont use the a/c much either coz im mostly running around town getting in and out of the car a lot.

only mod in the last couple of weeks - the Sports Lukey Exhaust, and that seems to have increased my economy too even with me driving it to be able to hear it better...

2002 TJII LE. Completely stock. 80/20 City/suburban driving i generally get 450(ish)kms per tank.
Actually pleasantly surprised at how good the Magnas are fuel wise. My old (1L 3cyl Swift) got destroyed and i was dreading the fuel bill for a 3.5 V6.... but no issues. If only the price /L would drop back below $1 where it belongs

Around town 10.3 l/100k and on a recent trip to melbourne 8.3l/100k. I usually drive fairly steady no thrashing or fast take offs.

Mostly city driving, anywhere between 10-14L/100kms - depends on how bad traffic is, number of shortcuts, etc. 01 manual TJ Sports. Managed to get 8.4L/100kms on a run from Adelaide Airport> Salisbury> Glenelg once. Don't have any highway figures I've taken notice of.

Just to throw something in from a completely different perspective...

I average about 17 miles per gallon on mostly around-town driving using premium (91 octane) gas. I'm paying about $4 US/gallon right now.

Ok, on your mark, start the conversion... ;-)

for the aussies
Its about 14/100km
and just over $1 a litre. lucky!

i do about 98% driving around town, short trips etc.
consistently getting around 12.7 - 13.4 /100km
thrash it a fair bit, tried driving like a nanna. but for short trips it makes no difference.

Premium's 95 or 98 RON here - 91 is the lowest RON petrol, so you're not really running premium at all

17mpg = 13.4L/100kms, not that bad, and that works out at $1.214/L... we're paying ~$1.50/L.

Wrong, US system for Octane is different to Aus. 91 Octane in is called PON (Pump Octane Number) or AKI (Anti Knock Index).

87PON in the US is equiv to 91RON in australia. 91PON is about 95RON and 93PON is around 98 i believe

1 us gallon is about 3.8 litres, we are paying AU$1.35 a litre so it roughly equates to about AU$5.10 a gallon which is a little more than you guys.

17 miles per gallon converts into about 280miles's per tank, which is about 450kilometres. Pretty average range for a diamante/magna
