I try to use kleenheat whereever possible, but its true... LPG certainly aint what it used to be, I had a mate many years ago that ran his 308's compression ratio @ 13.5:1 on gas when it was straight propane... he'd be in a lot of trouble nowdays!
My observations from 6 months of dedicated LPG running a Falcon wagon -
BP Gas seems to give me a better range going by the Distance to Empty gauge - on the Highway about 875kms
Shell appears to be worse particuarly around town (North Western Sydney)
and worst of all so far was VitalGas from a Mobil at Tamworth (I think) noticed an immediate drop in range, kickdown more often going up hills etc.
So I thinkl I'll stick with BP as much as possible - especially since they give a 2c discount with their free rewards card.
On recent trip (Sat/Sun) From Sydney to Bundaberg I averaged about 13l/100km with a fully laden wagon, with 5 people on board - used 202 litres over 1550km - cost me about $80 for the trip.
I'm running a 351C with an Impco 425 mixer in my XE ute and I only get 21L/100kms around town and about 16L/100kms on the highway. That's on either Shell or Mobil gas. I'll have to give BP a try now.
Still, I've got a 351 as a daily driver and it only costs me $20 a week to run so I'm not too worried. I can plant my foot whenever I like and don't have to worry about the petrol bill!! If only tyres were cheaper...........
As for the 2c a litre more for BP, if you're getting better mileage it probably pays for itself anyway.
There are two types of fools.
The first, who thinks that because it is old, it is good
And the second, who thinks that because it is new, it is better.
How much does a straight gas conversion cost for a 351?
those figures make me think about getting gas. Ive only had my 351 for about 3 weeks so Im still 'enjoying' the power getting the tyres warm and running it hard off the light but i have to fill up nearly every 4 days on petrol.

Not sure what a conversion would cost, used to be approx. $1,800. If its and old 351 you will also need to change to stainless valves and hardened seats. An old motor switched to gas usually burns valves !
For $1,800 you can buy a lot of real fuel.
I had an Eb 6 cyl as a co car on gas. It was always underpowered on gas, particularly noticable in the Snowy Mountains and it used approx. 20% more litres. Cold mornings, ie 0 - 2 degrees, would be lucky to get 300km out of a 60l tank. Normally, doing 5,000 km a month it was cheaper to run on gas.
When I bought the car for myself, I took the gas kit out and sold itfor $500. At 200km a week as a private car it wasn't worth having.
Trust this helps

Reason: 5000 km per month, not per week
