Not fantastic if I'm honest, 28mpg average at say 133.9 fuel, would mean 21.42 pence per mile.

Which is what I get now, from the 2.2, my record was 10.5 pence a mile  (at 69.9p litre)

Once again, you are completely missing the point, trying to justify to yourself your own views

If you do the calcs on the petrol usage of TBE (the top few were purely petrol, no LPG), you will see its about 27p per mile


Additionally, remember, I don't have the luxury of cheap LPG. Brackley BP is the cheapest for 20 miles

Suggests an average of 22mpg on petrol?

I also don't have cheap LPG any more, as I rarely go past Asda at High Wycombe.

  57807         184         28.26         1.299         36.71                  29.5995

According to your figures you nearly cracked 30mpg, remember I was slated for claiming that from a 3.2 

Thats 19p a mile, so 4p a mile saving 

[Entwood]

There's also a huge difference in a 4 pot V V6 on LPG and the way you drive v the way Jamie drives ... the less fuel you use the smaller the advantage of LPG ...

Again, plucking figures to convince yourself.  How do you think I managed nearly 30mpg? By driving like you (due to the old dears in that back, coming back from Cardiff at 70mph), and notice it was a short fill - trying to see what MPG I could get . I'd expect to easily break 23mpg (easily) on gas doing that, so 69p*4.5/23m = 13.5p per mile being miss daisy, and at Asda fuel prices...

You need to compare like with like, rather that trying to convince yourself that you are saving by using petrol

I'd say thats about what I was getting from TBE.

Fwiw seeing between 21 and 24 mpg from mine, doing mostly town/local work only manage to get north of 26/27 on a motorway cruise at the limit, not often enough to have much impact on the overall average.

Coverting to lpg would mean paying less for the fuel in the first place, but would in no way mean buying less of it...

You are clearly not trying hard enough, Mr Al

Given your figures for petrol are not dissimilar to TBE's (no surprise), you can see from my figures how mpg would drop, as would fuel costs

[Entwood]

Just my quick input ...  last 3 fills, which include the motorway run to the lakes and back ..

Total LPG (ltrs) 118.66
Total LPG (£)  £83.09
Total Miles 583

Now that works out at 14.25 pence/mile.

As I was running on gas I don't know what MPG petrol I would have got, but at the average price of 126.9 p/litre (£5:76 / gall) I would have had to have achieved 40.43 mpg to get the same economy .. and to get that from a well laden 3.2 is just dreaming...

At 30 mpg the saving would be  4.95 p/mile
at 25 mpg the saving would be  8.79 p/mile
at the 23mpg the computer "thinks" I was getting on petrol the saving was 10.79 p/mile

I drive like miss Daisy and cant get anywhere near those figures in my 2.5. I did wonder if it needs setting up,but LD had a good gander at it not that long before I bought it and he was happy enough with how it was setup iirc.

Yours is not perfect by any stretch... Perhaps I should have another look at it soon
