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

[Muteki]

KF verada gets 550-800 per tank my fiance drives that one.
TJ series 1 advanced magna with 2 1/2" exhaust gets 600/tank pretty consistant me driving. (mine)
TJ series 2 executive wagon stock chockers with audio and 18" rims gets 800km/tank roughly seems to float between 8 and 9ltrs/100 (mine)

TJ Ralliart Magna also mine varies allot depending on who is on the road and who needs to be shown how fast a magna can be ^.^
I can get it to sit as low as 7.2/100 and even lower when drafting off my fiance's mums car 4.2/100 =P usually tho it gets around 10.2/100 as an average of 6weeks.
If I avoid 100/110 zones and only go with the 80 zones to work I get a consistant 7.9/100.
And if i go on car cruises a tank averages around 11.3/100 but it boots hard not too many commodores it cant show up effortlessly.

Also my brother and his mate's cars
TF executive 3.0 wagon we consistently got 6.2/100 that car was a freak. on a long road trip to Melbourne we would get 1100km from a tank I think it must run on vapour too?

TE altera sedan 3.0 he gets 650 a tank 'he's worse than me feet are made from lead i think'
KH sedan 590-650/tank
VRX S2 600-700/tank

and finally his mates car

TL AWD VRX ahh.. this is funny the ralliart flogs this thing through corners and that was the selling point /shame... ok so
his car uses 10.5 if he drives like a granny and if he drives with us a nice little figure of around 14.8-15.5/100 that thing drinks fuel.

so there you have it 9 cars and the average fuel for all nine just for shits n giggles. 9.22/100
