You need to try harder James... I couldn't have gotten 450 miles from £100 of petrol more like £130

Would cost me about £80 in LPG mind

A good example of how you cannot compare the fuel economies of 2 completely different drivers though Especially as the figures I quote are based on what I would call "taking it fairly steady"

I'm lucky if I see 270 out of a tank now, even if 3/4 of the tank is done at 80mph cruise

The most I managed on petrol was 300 miles or so, although I did only run about 4 tankfulls through before LPG was fitted... I remember the surprise when the light came on at around 290 miles the first time though

You are all just fat gits, I've yet to get less than 300 

So far 320 - 340 ish....

Not done many long runs in it really, off to Norfolk next week, but with 2 bikes on the roof & boot full of camping gear going to be bit crappy in mpg

Where are you going to?

As for being fat... I think it's more that we push the loud pedal a bit harder It revs to more than 2000 RPM you know

[tunnie]

Main routes are Brackley to West London, which is mostly dual carriage way & motorway. Also do few runs of West London, down to Kingston upon Thames. Cruise usually spot on 80mph with cruise set, when on the motorway for the 75 mile run back.

If I'm honest it rarely revs above 4k, much like my 2.2 

Other than that, avoid braking as much as possible, by looking ahead. Quite a few short cuts around here, to avoid lights and be stopped for a few mins.

I would think it more economical to sell yours and buy an already converted Omega for likely the same price!

But you are buying an unknown entity Assuming the op has got his up together and done all the main problems that occur then he might have to do all that again on a new one

[Strangechap]

That's a good point. I've already checked mine out and serviced it, done the breathers and rocker gaskets etc so I know it's sound, plus I was fairly specific about what age and spec I wanted. I've not seen any others come up with LPG anywhere close.

I dropped the car off with the guy this morning. Lovely bloke, very knowledgable. Explained what he would do and discussed what my commute was like as he would take that into consideration when setting the system up. He showed me a BMW he had in for some work that he had converted about 6 years ago. Still going strong. I had a good look at the quality of workmanship and it was spot on. Everything neat and tidy. If I hadn't know what to look for, it would have looked like it was there when the car was made.

So I'm in his hands now, we will see what I get back next weekend! Thanks for all your advice chaps. No one jumped up and said 'stop, you're a fool!' which reassures me somewhat.

You need to get a 2.7 CRD Jeep, much better on fuel............

[05omegav6]

Tunnie you're missing out on the best third of the engine

The noise as it pulls through 5k on the way to the red line is worth every bucket of fuel

Might explain why there are so many broken autoboxes though

[Radar]

Keep us updated Strangechap and hope it all goes well

Here's some maths for you:

The current "combined" fuel cycle for the PFL 3.0 auto Omega is: 23.7 MPG.

£100 x £1.41 = 70.92198582 litres divided by 15.60096476 gallons, times by 23.7 MPG =   370 miles per £100.

Now, using the same maths above and knocking off 4mpg for running on LPG (guesstimate) will be 19.7 MPG.

£100 x £0.78 = 128.2051282 litres divided by 28.201744 gallons times by 19.7 MPG = 555 miles per £100.

So according to these calculations, you will gain an extra 185 miles for every £100 of LPG you buy compared to petrol.

Which means you would have literally cut your fuel costs in half. (Half of 370 = 185.)

Hope this helps...

[albitz]

Dunno if Im missing something,but to cut fuel costs in half you would need to achieve 740 miles per £100 (2x 370).

[Kevin Wood]

Yep, no way will LPG halve fuel costs. It can reduce it by up to 50%, IME, which is actually what your numbers are saying (370x1.5 = 555).

What Kevin said.  Your figures show that you are making a saving of 33.3%, not 50%.
