With a Unmodded 5.0 v8 in an EF ghia, on LPG- from peoples experience what should I expect out of a full tank of gas- on freeway at 100 with cruise?

My 6cyl 5 spd Wagon Never gets any less then 500k's from 70L LPG....so I am thinking a conservatively driven 5.0 should be around 400???

If your talking Highway, my 5.0 gets 500km/tank on LPG. Parnell system.

My 5.0L wagon with 80 usable litres and equipped with headwork, cam, exhaust etc gives me 500km +-30km. Thats with the Sprintgas system.
