Good to know. Thanks for feeding back. I'm still in doubt as to replacing the L-sond should give me any improvement though. >BTW, what miles per litre(or UK gallon) do you get? Some people on here say >that the 25 miles /UK gallon(4.54 litres) is too low. I would be interested >in your findings. Actually, I reset the display everytime I fuel up, 'cause I'm kind of keen on consumption, however I'm in metric-land, so I don't know if these figures make sense to you. Normally on day to day LPG driving, I get 12 to 13 L. / 100Km's. That is when I still had a job, and would commute 2x35Km's a day , of which 25Km on a 80Km/h dual carriage way with roundabouts and trafic lights, and 10Km on motorway up to 120/h Nowadays, with more short trips & city traffic it goes up to a fearful 13 to 14.5 L/100Km. On a long motorway trip (drove up and down to Paris on one day recently, totalling 800Km's at up to 150KM/h+ some city and congestion trafic) I reached 11.5L / 100Km average, on LPG. The last long trip through Germany, at somewhat higher speeds, but on Petrol (no LPG available there) I got down to 9.5 to 11 L / 100Km. That's with a no turbo SAAB 9000 2.0CSi 96 kW (130 hp) from '95 (X-posted into alt.autos.saab)
