Yep timing, plugs, leads and mixture need to be spot on for lpg to get reasonable economy. These things have been mentioned frequently on this forum, p.m. me if you need more specifics.

3.9 (supercharged), takes 58L (80% of capacity) and does 180 - 205 klms depending on how it is used that week.

The gas installer said that's about right as you use 20-25% more gas than petrol for the same running (uses a manifold injection system).

.....So, if you work out the cost of gas (86 cpl) versus LPG (130 ish cpl) in Tas atm, it's just not not worth the cost of converting (5.7k)

i use 70 ltrs of gas for 400kms with 2 persons and camping gear, with a 3.9ltr with 255000km and not pussy footing it on the highway. my km/ltr of normal highway driving and towing 700kg i use 21litres per 100km (on fuel i still use 20km )
