55 litres divided by 4.5 equals 12.222 gallons, 265miles divided by 12.222 equals 21.68 mpg,so how did you work it out to get 50 mpg??

Top of head that's about right. Remember your figure is looking at petrol. Price difference between the two is 135% (60p to £1.40) so around 50mpg seem right.

So Ray's correct in that your actually getting around 22mpg. What you really mean is that the cost of running your car on lpg is equivalent to around 50mpg lol.
As I've decided to keep the car until the end of 2013 (longest car I've ever owned by then), I'm revisiting this point with some additional background.
1. Had 300c on petrol worked without issue. Never had MIL light on, stutter or hesitation!!!
2. Had top of range BRC kit put in by a reputable lpg installer. During installation, I recall they stated they connected the lpg wiring loom incorrectly which "blew" the battery. They replaced the battery with a new one. Went to collect car and MIL light came on as just driving out of their garage. Took back and they found fault with ECU (blown as not responding) so they ordered new one from Chrysler which took 3 weeks (lucky as dealer also in Coventry!). They fitted and MIL light went off but then didn't put the EGR blue seal back on correctly which caused a vaccum leak causing MIL light to come on. They had car for 9 weeks by then so decided to take my car back and drive with small leak for a few days whilst they order the new EGR seal. They got new EGR Seal and managed to break it whilst putting the upper manifold on!!! To seal up the leak they used black manifold gasket sealant which sets and goes hard. Left garage at 8pm. Also changed one oxygen sensor as code came up for this (sealant they used clogged it up?) Other issues here about damaging bumper and filling in with "brush marked" paint and blaming Chrysler but won't mention here! Lost all faith with them - MIL still on.
3. Then had lpg system serviced by a guy I had used before. Really nice bloke who really knows his stuff (mobile he comes to you). Informed me that LPG installation quite good (apart from JIC LPG pipe exiting throughout metal (no insulation)).
4. He replaced the blue EGR seal and carried out service on LPG and Petrol. There appears to be no leaks but still get the p300 code and MIL stays on as stated above and flashes once in a while when stationary and stutters (on petrol and lpg). His notes state "Engine showing P0300 multiple random misfire on petrol and lpg. Bank 2 fuel trims at +18 indicating an issue and injection times varying from 2.7ms to 3.8ms rapidly".
5. He recalled that he stated that there was a recall for 3.5 due for sticky valves (I've run bottle of seafoam through vacuum pipe - didn't help but lots of cabon smoke!). Otherwise, the ECU may need updated software (as this was replaced and may not have been updated). Could be a faulty injector? Faulty spark plug?
6. Being doing this for the last 24k miles but runs extremely well. Service due soon but oil is still golden after 12k on lpg!)
7. Got Ray's details now as local from where I work and intend to call in New Year - but may take to Chrysler first to see if they can update ECU. Ray do you have equipment to do this?
I can update some cars,it all depends on what my monthly updates have been updated by the company and I never know until I plug it in to a car,up to now I can't update Chryslers but tomorrow ( apparently) is the latest update so you never know. As I posted earlier a mate had his Hyundai sonata LPG converted and had the same code and I put it out,it's worth a go on my machine.....Nowt to lose...if you get my drift....
Mines the dogs b0llox...lol,it's a socio 600 by tecnomotor from Italy ( where else ay,lol)...in my eyes and experience the best.....cost a bit...but worth it...I had the socio predecessor for 4 years previously and this one I've had exactly a year now....
