Title: LPG consumption
Post by: Solstice on October 26, 2015, 10:05:55 PM: Guys, some advice please, I have sort of acquired my parents 4.0 97 GC, it has had a multipoint LPG conversion and gentle bimbling is giving about 15mpg, throttle response isn't as crisp on lpg either, I'm wondering whether it is set up right ( I has a LPG Monaro a few years back and you really couldn't tell whether it was running on LPG or petrol).
Does the fuel consumption sound right, I'm sure if I wasn't being economical I could easily have it down to single figures?
Thanks

I'm getting between 13-17mpg.

It only ever starts and runs for a few seconds on petrol so it's not a case of 50 of those miles were on petrol.
