calling all LPG converted calibras

[superfox233]

i know what your saying and agree with it But gordy is saying that he gets 55mpg now thats a good 10mpg better than most v6 that i know of,

No no no!! He'll be getting THE EQUIVILENT OF 55 petrol-miles-per-gallon..... In reality, lpg will give him about 20mpg (ish). But!! It costs half as much to buy in the first place. Ergo, if you see the price of all fuels being equal to one-another, he'll be achieving THE EQUIVILENT of 55mpg!!!

EXP.
£50 buys 50l of petrol........and will do 30mpg
£50 buys 100l of lpg..........and will do 20mpg.......but you have twice as much.......so will achieve THE EQUIVILENT of 40mpg.

Make sense?? I really cant explain any clearer than this!!!

RIGHT YOU ARE TALKING CRAP

MPG is MPG end of story

you cant say that buying twice as much fuel still gives the same MPG he may get more miles per £

if you use 1 gallon of fuel no matter what it is the amount of miles you get is your MPG
and if you use £1 of fuel no matter what it is the amount of miles you get is your miles per £

Now that is it as clear as it gets

[big_gordy]

right its either 35 galon or 45 galon lpg tank costs me about 25-30 to fill up and can get me from my house to billing without filling up!

does this help?

no not realy
is it 35 or 45 ? and how many miles is it from your house to billing ? then we can work out you LPG MPG

i dont know how many miles to Gordys, from billing, but my house to my brothers,so that is corby to carluke is 331miles, i use 3quarters of a tank of petrol, so i would say it would be near or so the same amount from billing to gordys asmaybe 340to350 miles

[Fraz]

360 miles from Gordons to Billing (give or take a couple of miles)

[Allys Cally]

should that not be a 35-45 litre tank

[Allys Cally]

never thought of that

[Fraz]

Right so you spend between £25 to £30 to fill your LPG tank up, current prices for LPG (from a website) round your area is .57.9 per litre …so even if you take the least amount

£25 of LPG = 43.17 litres …. 43.17ltrs = 9.5 Gallons now if I did my sums right …360 on 9.5 gallons = 37.88 MPG

Even worse at £30 = 51.8 litres = 11.39 gallons = 31.6 MPG

And did you not stop at the services same time as me and fill up the tank on way down this year?

so between 37.88 and 31.6 mpg so where the F*** does 55MPG come from

[Mark1]

Don't care what mpg it gets I'll never be putting it in any car of mine. And SE9's never came with LPG

RIGHT YOU ARE TALKING CRAP

MPG is MPG end of story

you cant say that buying twice as much fuel still gives the same MPG he may get more miles per £

if you use 1 gallon of fuel no matter what it is the amount of miles you get is your MPG
and if you use £1 of fuel no matter what it is the amount of miles you get is your miles per £

Now that is it as clear as it gets

I give up! Its all about THE EQUIVILENT COST AND THE DIFFERENCE BETWEEN THE EFFICENCY OF EACH FUEL!!!

I'll attempt ONE LAST TIME in THE MOST SIMPLEST of terms. Just for you!!


EXAMPLE:

PETROL: It will cost £1.00 to travel 1.0 mile. (100% efficient)
LPG: It will cost £0.50 to travel 0.8 mile. (80% efficient)


To work out the EQUIVILENT mpg:

PETROL: In the above exp, Lets just say you are achieving 1.0mpg
LPG: Again, using the same exp, You'll only achieve 0.8mpg.


THE "COMPLICATED" MATHS BIT:

Double the amount of LPG to match the price of petrol:
£0.50 x2 = £1.00

Respectively, double the mpg that you get with LPG:
0.8mpg x2 = 1.6mpg


THUS, THE EQUIVIELENT MPG AND COST IN THIS EXAMPLE IS:

PETROL AMOUNT FOR £1.00: 1 GALLON
PETROL MPG: 1.0

LPG AMOUNT FOR £1.00: 2 GALLONS
LPG MPG: 1.6


***OR***

THE SAME £1.00 THAT BUYS 1.0 GALLON OF PETROL WILL BUY 2.0 GALLONS OF LPG.
2 GALLONS OF LPG WILL ALLOW YOU TO TRAVEL 1.6 MILES.

PETROL MPG: 1.0
LPG AT EQUIVILENT COST MPG: 1.6

So what have we learnt today class?? We have learnt:
- That LPG at base cost price will only allow you to travel 0.8 miles
-But if we compare it to the same price as fuel, we will be able to travel 0.6 miles further!!
-So this means in 99.999% of cases, that whereas LPG is only 80% efficient compared to petrol but because you get twice as much for the same price, it works out to be cheapest automotive fuel to use for your car.

.............now if that isnt clear, I recommend you leave this topic and stop boggling your head with it because you'll never get it!! Its not as if its degree maths here. Just simple understanding!!

RANDOM LPG FUN FACTS
We can also state Jason Plato's recent argument about some BTCC cars using LPG as an unfair advantage as the engines are producing MORE hp than race fuel!! Another quick fact for you is LPG is used in the Palmer Jaguar race car at Oulton Park as it produces "around 50hp more than standard track fuel".

Now i'm not saying your standard road engine will produce more hp with LPG because it wont!! These race engines are specifically engineered for it!!

[superfox233]

You're seriously thick as F***!!

Read my last example. Again. Slowly. Very slowly in your case....

I'm not arguing. Just stating the logic behind the point of LPG. There is no argument. Its just the way it is!! Why are you throwing random variations like money off vouchers in there?? You've not lost pal. Just missed the point...........

[superfox233]

Just googled "lpg equivilent costs" and heres a few copied statements from people with half a brain who understand.....

"So far the van is doing 22 mpg...with lpg at half the price of petrol that's the equivalent of 44 mpg for a van...and LPg will add maybe £1000 to the value of your vehicle....and for an annual fee f £10 you can avoid paying any congestion charge...." http://www.navitron.org.uk/forum/index. ... pic=2192.0

"I'm over the moon with it ! There is no difference running the car on LPG or petrol. I have reduced my petrol bill by over half thanks to the cheap LPG prices where I live." http://www.lpg-cars.co.uk/customers/

just a couple. Do your own 2 minute search and then eat some humble pie.

[Fraz]

the problem is your doubling the MPG because the cost of the LPG is less than the cost of unleaded, so your assuming that you get more miles per gallon because its approximately half the price of unleaded

yes you will get further spending the same amount of money....but your not getting more MPG

so if LPG was the same price as unleaded ...does he still get 55 MPG ??

I had to work out the average fuel cost of our fleet of vans and at no time did I use the price of the fuel in the equation. it was all on how many litres of fuel it used in a month and the amount of miles in a month...however if I then wanted to work out what was the most cost effective then I would then have to get the total amount the fuel cost and work it out ....that is not the MPG though its the cost per mile

Miles per gallon is how many miles you get on a gallon of fuel ...it dont matter what the fuel costs.

If I buy a gallon of fuel at £10 and get 10 miles how many miles per gallon is that ??? 10 miles per gallon

if I then get a gallon of fuel at £1 per gallon and get 10 miles .. 10 miles per gallon

the bottom one is obviously the cheapest per mile ...but its the same MPG
