i get 10.6 litres/100km on my EL Ghia but i drive like a grandpa

10.9L/100km city driving
7L/100km highway.

Range counts to 800+ sometimes.

im not sure of the maths, but i know i can get nearly 5hrs of driving from 30ltrs of fuel (i had to do that a couple of times )

the best i got from the ea ws 506k's,,,

My El Wagon done 750kms p/tank on the way to Brisbane, around town though I'm luck to crack 550kms from a full tank. Premium dosent seem to go any better, except the car does run smoother (no rough idle).
My work car (AU III str8 LPG) is a dog around town, wont get muck more that 400kms, but open road will get around 600kms p/tank.

I have notices my EL will chew it more from time to time, both city and country driving but it maintains a decent count. I really notice a diffrence going from my local independant servo (s**t economy) to filling up at Shell or BP (always better). Bp seems to be the best I recon.

Try driving a BA same engine only heavier
