LPG is about 15% less efficient than petrol as it has a lower calorific value...

I run LPG and I average 15.3 on LPG, computer regularly returns 18mpg. 15.3/18 = 0.85

I don't work out the equivalent in a theoretical MPG, I work it out as Pence per Mile...

On LPG I return 22.3p per mile @ 15.3mpg

If I was running 250 miles on Petrol at 18mpg at £1.31p/l that would be:

250 / 18 = 13.89 gallons

13.89 x 4.54 = 63.06 Litres

63.06 x 131 = 8260.86 pence (£82.61)

8260.86 / 250 = 33.04 pence per mile

If I was to work out the equivilant:

Petrol Price = 131p per litre
LPG = 72p per litre

72 / 131 = 0.5496

15.3mpg / 0.5496 = 27.8mpg

But it is not a true figure and is purely theorectical and means nothing really....

Price per mile is a more accurate way of judging cost saving

Try explaining that to Martyn. Oh you just have. :D:D:D
 
I thought it was clear we were talking in equivalent MPG from the start. You can work it out as pence per mile or for a more general understanding convert to MPG as most folks find this easier to relate to for comparison... well i say most folks.....never mind wammers:rolleyes:

No you said you were getting X MPG on gas, a positive statement. That was not correct. You are getting LESS MPG on gas but paying LESS to do it.
 
Wammers, i do beleive i said MPG equivalent but if you want to be anal & pedantic then then you go right ahead fella.

My P38 always seems to attract interest & i'm usually met with the question 'i bet that drinks fuel' to which if i reply 'well actually on a good run it can cost as little as 18p a mile' would usually result in a blank expression. Now if i say, 'well actually with the LPG, on a good run it gives the equivalent of around 32mpg' ....that's something most folk relate to.
 
Fixed the passenger side heated front seat. Not that hard to do just a bit time consuming. The thermostat was broke on mine all the wiring was fine. Works a treat now. Wished I'd done the drivers side now but wanted to make sure I could get somewhere if it all went "Pete Tong" and I needed some other bits/tools. Perhaps next weekend!!
 
Just back from a few days in Paris.....undertaking initial deep clean before leaving down tomorrow for Dinitrolling

Well said pal
 
...but running costs are mostly due to depreciation..........by the time they get to this age.....its no more than running a super-mini......:)

If the cost of fuel concerns you, Range Rovers aren't for you. Stick to the Smart Car.

See that little gauge in the left of the instrument cluster? When it gets near the red bit, I'll put some motion potion in and pay the nice lady. Who cares how much they cost to run? That isn't the point, it is what they can do for you.

Yeah i know he is a real star. If i run my car on old chip oil at 45p a litre i can get the equivalent of 90 MPG on a good run. Or around 2.27 pence per mile. Up yours.
 
mine runs on a bio diesel/ cooking oil mix which works out about 90p a litre does that make mine a lean green enviro machine :D:D:D:D

Yeah you is green man. And if you get 28 MPG on a good run it gives you the equivalent of 42.28 MPG or 9.6 pence per mile. In gas guzzler parlance at least. :D:D:D
