S6 Avant LPG conversion

[MacGee]

just recently got 30,000 mile S6 Avant. Great but just apprx 16 mpg. Anyone done LPG conversion. Is it possible, worth it and Ok for engine etc. Your thoughts please.

I'd get it looked at - my RS6 with a bigger engine and twin turbos bolted on, driven hard pretty much every day was giving me more than that (just).

[daphantom]

i was getting 14mpg out of my S6

[Reeso]

I'm getting around 20mpg on combined driving, a bit less if you kain it, say 15mpg and up to 24mpg on a long run.

Mate of mine has had his 54reg S4 LPG'd.

£2500 and he can't tell the difference between running on petrol and LPG.

Range is about 200 miles on LPG, savings are about 45%

Is it the same engine?

Sad , how to knacker up a perfect engine managment system,hope they are all out of warranty, and what a good repair bill you,ll get WHEN a component fails....hope the GREEN saving is in the bank account.!!

That's what I've never understood about LPG. If you can live with 200 mile range then surely you don't do enough miles to care about fuel economy? I'd be going to the filling station every other day!

lpg specialist has emailed with quote of £3000 + vat for conversion (2x5 cylinder packs). Bit excessive for my needs. My petrol tank only doe approx 200 miles, so lpg would double range. However, I would need to drive about 2 years before recoup of outlay. Looks like will have to keep destroying the earth!

Why do people buy cars with such big, thirsty engines and then worry about fuel costs?



Always confused me this one.

Cake and eat it springs to mind...want the performance but not the accompanying fuel bill..

Isn't that just part of owning a car with such a drastically big engine? The greater the performance, the greater the ownership cost will be? Surely.

Unless your hurling around in modified Jap Crap.

I apologise my naivety.

donutsina911: You knew your lovely RS4 was a 4.2 when you bought it and realised big petrol bills will follow your ownership...

Wonderful car though.

Yep - when I said cake and eat it, I wasnt talking about me I had no illusions about fuel when I picked up the Audi

[MacGee]

have driven V8's (TVR's,range rovers, etc...)before and didnt manage to go as low as this before.. not moaning ..just enquiring if any tricks to reduce my taxes to gordon!
when purchasing decided that if went for big diesel would prob pay £5k more up front(& not get anywhre near performance)...this pays for a lot of fuel. so no sour grapes.
