Gas V Diesel

Ive decided to seriously consider this option, but i do need more info about it.

Currently a 1.8 Diesel 18,000 Motorway driving a year.
45L Tank and that gets 460 miles motorway driving.
So its pretty much £1 a liter to make it easier.

So for every 10 miles = 1 liter of Diesel.
or £1 for every 10 miles.

So for 18,000 Miles = 1,800 liters of fuel a year.
That means £1,800 on fuel a year.

Now if Gas is %50 cheaper ( In theory ) that would make
a Fuel Bill of £900

So if Fitting was £1000 + year Gas £900 = £1900
Were as a year of Diesel would cost £ 1,800

So year 2 would have a saving of £900 from the diesel
+ £100 over costs from the year before, so

Year 2 = £1000 in Gas and Not £1,800 if Diesel.
Year 3 = £900 and not £1,800 in Diesel.

Anyone have any links or advice?
As the numbers look great but what's it really like?

i had it on an old rover v8 3.5(last of the mk1 shape) range rover (sponsered by bank of dad) and it was well cool but i did mine with a calor gas type bottle in the back and could by them in lots of places but as for how it ran i found it pretty much the same, without doing any hard maths on road i found little difference but off road (mainly sand) she seemed to guzzle gaz the same but seemed felt a little underpowered. all in all the it was well cheaper, ran it on go go for 10 minutes then flicked a switch and of she went and cleaner to.

Mark Top Tip, buy a kit on ebay and away you go

I cant i have a diesel...

Just thinking down the road and getting some homework done.
I'm thinking either another fiesta petrol or focus.

Humm what would be the best motorway fuel economy engine?
I'm thinking 1.4 or 1.6 ??

Its all about saving money. ( In the long run )

depends on gearing or if u gonna go that small how about a polo bluemotion

bit bigger but honda accord, bigger engine but very economical

1.6 more headroom for motorway's, but make sure its over 100bhp. I know you're not looking for performance, just somthing that is reliable and get's you from a-b.

Maybe summit Jap? A Honda Accord would be very nice, but if you are wanting to stay with the blue oval, probably better off with a Focus given their lower pricing nowadays.

You can always pick up pre-converted Vectra's and the like if you were ever to make the jump; but as always, you're number one priority is reliability due to the nature of your missus's work, so it is important the engine doesnt miss a beat.

Hence I would go for Jap for petrol. Make sure whatever it is, it come's with the relevant certification's, as I think some insurance companies will penalise a non-certified installation.

The price of diesel is scandalous atm, at it is getting to the point where it is no longer any cheaper to run a derv then a petrol because the extra milage you make per gallon, you are paying upward of 40p for.

Food for thought.
I didn't realise about any official certification
May have to do some digging at the insurance to see if
the are any pit holes i need to be aware of.

diesel is the way....come to the dark side luke...i mean mark...

He already is derv haha

diesels are crap, well most ford ones are and french ones. always breaking, horrible to work on, dirty and the power (if you have any) is all in one big narrow lump.

germans might be different tho

Bit of a thought mate, there's a little garage around the corner from mine and he sells diesel for .85p a litre( don't ask me how!) . My missus drives a diesel an im thinkin of going to him, just haven't got round to it yet. Another thing to think about mate, as you've already got a diesel, is a unit which converts used chip oil into biodiesel, it was on fifth gear a few weeks ago an im sure they said its safe to use in a diesel with no modifications needed.
Just a few more options for ya anyway.

hell yes...until the injector goes!

I take it you mean the Biodiesel place... I used it a few months back and was rather good... but not so good for cold starting.

Me think's I will return to using it again in the summer, but I dunno just yet.

Not sure if Mark's can use Bio as not all car's can, but I did suggest it to him once when I was running it. Would need to find out if it is suitable for his car though.

my corsa is a diesel 1.3 cdti it nippy enough but lookin to get it mapped in the future which nearly doubles the torque figure so should be pretty quick then

i looooved my VRS's engine!

The cheapest way of doing it Mark(as I have recently done) is to buy a car already converted to LPG:) Then you get all the savings with no outlay for a conversion!

no substitute for cubic inches...diesel IS the way....

I was thinking that

Anything to watch out for?
A leak would be the obvious lol...

Make sure any converted car runs PERFECTLY when its on gas...most common faults include stalling at junctions and holding back on hard throttle...

It's also strongly adviseable to have the correct certification for the install; an install without the appropriate certification can cause you problems with getting it insured and can also lead to problems further down the line if the install hasnt been done correctly.

ther is some dodgy stuff on the market but if done right by a reputable company works well

i like the sound of a vrs they sound lke fun!

Be a bit warey of it atm, because there is suspsicion the government will be ceasing the tax break on LPG in the next year, to generate an extra £50 - £60 million revenue, as well as the fact that it is only around 16% cleaner then regular petrol and a recent government review concluded it should'nt be classed as a "green" fuel.

It looks like the future is not LPG after all; and diesel is set to hit £1.50 per litre by the end of the year (most analyst's are predicting it will hit it by November 2008)...

Bit of a problem with some bio diesels!
they have to mix it with a certain percentage of diesel, but depending o the mix depends how often your fuel filter clogs! Mate had his van running on it and was costing him a filter a month!!
And smells of chips!

He must be using very poor quality bio derv, or even poorly treated, used cooking oil.

The reason for the filter clogging is the thinning agents (solvents) cleaning the diesel system - shifting old dirty deposits though the system in to the filter.

First time of using boi diesel, its suggested you change the filter after a couple of tanks as that will be sufficient to catch all the shifted dirt in the system.

If your clogging the filter after that (more than a regular service interval) then change supplier as there is still crap in the diesel - there is nothing in bio diesel to clog a filter.

My lpg demon...540i manual 6 speed with lsd

Interesting to say the least.

I cant afford a H2o car at £50,000 lol

Humm Decisions Decisions...

£1.50 a litre

Looks like i will have to get the MPG Calculator out then.
