Post by: tommycon on 27 April 2009, 20:18:57

hiya,
 i`m thinking of buying a 2.5 auto on LPG, i know i used to get about 80 miles from a £20 with my 3L auto,
 has anybody got a 2.5 auto on gas to advise me on what i could expect to get to the gallon and what faults to look for.
 many thanks Paul

My 3l does a comfortable 300 to 72L of gas... Mixture of town and fast A driving. On a sensible run I saw over 350 miles with gas in the tank still!!!

2.5 sill probably be about the same TBH.

Check thoroughly it is a Sequential system and that the coolant feed is taken from before the HBV :y :y

 this 2.5 is fitted with a mutipoint system,, i really dont know anything about LPG so how would i check it is actually running on it rather than petrol???

Right...

Standard Omega checks to begin with. Paperclip it etc...

The switch will have lights and the seller will show you how it works. Once it's running on gas you should be able to hear/feel the LPG injectors working.

Do you know what make of system it is?
