oh dear......oh dear........LPG face the facts from an owner of a punto 1.8 hgt (my previous car) .....cost me then £1400, tank fitted was a 40litre, my car did about 32mpg on petrol, I lost 15 -20% consumption (YES!) it was that crap (the higher you rev- you guzzle LPG). so I was always having to stop at an LPG site with a shitty range of about 200 miles ish
thats another
problem - still hardly any LPG sites - believe me this does get to be a complete pain in the rear - also takes longer to fill up (beleieve me this does pee you off - after a fast flow petrol pump) - also really annoying when one LPG pump - and you have to Q for it (!!!!!) ...this really will get to you (every day!!!!)
you do lose power - the guy that said you gain power is a LIAR!!! plain and simple.
I reckon on 5% power loss, at least!
LPG is only good for large engined motors - 3 litre plus - dont go near it for anything sporty/tuned.
And to cap my experience off - I had a blow back (basically a back fire)- whilst on LPG - My system was dual switchable, the inlet manifold exploded - loads of smoke - thought the whole car was going to blow up!!!!
(ON LPG a back fire can be catostrphic as LPG so explosive - petrol backfires as we know are just embarrasing - no damage!)
Seat will tell you to F**CK off - rip up ypur warranty - I kissed goodbye to a £1200 repair bill with sweet FA from Fiat - believe me I tried to get money back,via my solicitor - no joy.
I ended up getting the system taken off then selling the lump of shite!- at extra cost by another company - who then told me that the origianl system was nothing short of ilegal -yes if I'd had a rear end high speed -- BANG!!! bye bye me! no gas shut off valvle fitted , it wasnt even safe! the company who installed - have now gone tits up! so no comeback now anyway.
stay clear the industry is full of cowboys - AVOID - do not ruin a great car!!!!
GET A TDI 150 - dont ruin your CAR! ............... PLEASE
