chan110 Posted February 26, 2012 Report Share Posted February 26, 2012 Hi, NEW here, pls can u help with the following: 1. I have a LPG Subaru Legacy - but would like a change, so looking at an A8 4.2 (or A6 2.7 bi-Turbo) - anyone got any of these? 2. Does anyone know which is the best LPG system for the A8 or A6? 3. Someone here mentioned abt corroding if drill into the aluminium body - is this possible? 4. What would I need to look for when buying a LPG A8 (or A6) or just plain buying an A8 or A6? 5. Costs seems to be a factor, my Legacy is expensive to maintain, but using salvage parts/indy does save a bit, have people here manage to source cheap 'reliable' parts and plenty of indy's in the country? Many thks! Link to comment Share on other sites More sharing options...
daljames Posted March 3, 2012 Report Share Posted March 3, 2012 Hi, i have a 1997 D2 A8 3.7 which i have recently converted to LPG in Australia. I went with the AG centrum kit which i bought off Ebay UK and had installed. I did the tuning myself as it comes with the software. So far, its only been 2 weeks, very happy with it. Consumption figures are around 12l/100km on petrol or 17l/100km on LPG around town, but i am a light foot. I absolutely love this car which i have had for over 6 months now.

daljames Posted March 4, 2012 Report Share Posted March 4, 2012 Will do. Update on the fuel now i have finalised the LPG map. I just did 2 return trips to work, 164 klms and used 22.4 litres of LPG so it works out at 13.7 l/100kms Link to comment Share on other sites More sharing options...
A8_Tony Posted March 19, 2012 Report Share Posted March 19, 2012 Chan, I recently owned a 2.8 A8 with LPG. And whilst the feeling of putting £40 of fuel in the car to then cover 250 miles felt great, having worked out the MPG, it seems it was returning around 20MPG. Not brilliant, but not too bad. Now, based upon some calculations I've recently carried out I reckon the following figures to be fairly accurate: [TABLE=class: grid, width: 500] [TR] [TD]Car[/TD] [TD]Tank Size[/TD] [TD]MPG[/TD] [TD]Cost/mile[/TD] [TD]Cost/15k miles[/TD] [/TR] [TR] [TD]A8 4.2 LPG[/TD] [TD]60[/TD] [TD]18[/TD] [TD]18p[/TD] [TD]£2688.29[/TD] [/TR] [TR] [TD]A8 3.0 TDi[/TD] [TD]90[/TD] [TD]33.6[/TD] [TD]19p[/TD] [TD]£2922.97[/TD] [/TR] [TR] [TD]A8 4.2 Petrol[/TD] [TD]90[/TD] [TD]21.4[/TD] [TD]29p[/TD] [TD]£4302.30[/TD] [/TR] [TR] [TD][/TD] [TD][/TD] [TD][/TD] [TD][/TD] [TD][/TD] [/TR] [/TABLE] As you can see there's a significant saving to be had. But, these figures were based on LPG at 70.9p/litre. I've seen gas advertised today at 85.9p/litre so this would translate as follows: A8 4.2 LPG Cost/mile - 22p, Cost/15k miles - £3257.04 Still a significant saving. The prinz systems are supposed to be the best, but you'll be paying around £2400 for a system to be fitted to the '8 of choice. Link to comment Share on other sites More sharing options...
Tipex Posted March 20, 2012 Report Share Posted March 20, 2012 The governments promise to hold duty on LPG fuel runs out this year, so anyone thinking of fitting an LPG system is very brave, it won't be long before the price creeps up to almost that of petrol, and one it does, expect most of the forecourts to remove the gas pumps as LPG will effectively be dead.

Having seen it go up by 20% in less than 3 months, I can only guess that this is already happening. I paid 69.9p in December, and now regularly see it advertised at 85.9!!!!!

Tipex Posted March 22, 2012 Report Share Posted March 22, 2012 Really? looks like it's already started then! I don't keep an eye on LPG prices any more to be honest as we don't have any LPG vehicles, mainly due to the fact we got fed up of having to replace the heads on so equipped vehicles, LPG and high mileage do not go hand in hand.

snapdragon Posted March 22, 2012 Report Share Posted March 22, 2012 On January the 1st, the duty rose on LPG by 6p/kg. On August 1st 2012, the commitment to lower duty on lpg ends. Link to comment Share on other sites More sharing options...
daljames Posted April 7, 2012 Report Share Posted April 7, 2012 My fuel consumption figures on LPG are remaining fairly steady at around that 14 l/100km mark. I have some stuttering at low revs in high gears. Usually when the torque converter is locked and engine doing around 1100rpm. Thats the only real issue i have. I love this car. Am getting a new VW Polo though for running around work and where parking the A8 is a problem. I dont anticipate the Polo costing all that much less in $$ terms for fuel.
