Disco 4.0 V8 Consumption

What is it in real terms?

J S · 07 May 2008, 19:36

About 20mpg

People are getting around 300-350 miles to a tank i believe.

Depends on how it's driven and auto or manual - I would say 20mpg on a run but it could get as low as 14mpg in constant stop start traffic - then again there are so many traffic lights these days set to trap the motorist even a 1Litre Micra will do 0mpg sitting in a traffic jam!!!

I would get a DIY kit and gas it - still about 52p per litre - less in the right places.

I didn't know you could get a DIY gas kit. Are these DIY kits any good?

As for the economy, with petrol cheaper than Diesel and TDI's only doing 25 MPG it's a lot closer than one thinks in money terms. The Gas would swing it.

I guess there's more available power with the V8?

I find the real advantage of diesel is the economy on short hops to work etc. I drive mine without the turbo even kicking in most of the time and it's cheaper on fuel than Sixy's old 1800 Golf.

Don't you need an installation certificate for your insurer? Can you get this for a DIY installation?

And... didn't Mr Darling ("don't call me Darling") hint that tax might be phased in for LPG in a couple of years time (yes, I know he might not be in the job that long!)

OMG I feel the need for another slant on a Blackadder quote!

"You mean those kept in a vault in the Bank of England? Found 'em, nicked 'em, spent 'em!"

The kits are exactly the same as the ones the pros use. You can either have someone examine your installation and give you a certificate or some people who supply the kit will do it for you but they aren't cheap. I don't think you HAVE to have one anyway.

The ultimate setup is to have 2 tanks where the fuel tank used to go and a smaller petrol tank in the wing. No loss of ground clearance and no loss of boot space.

The V8 is FAR nicer than any diesel to drive - smooth - loads of power - quiet and you hardly need to change gear!!!

Actually LPG seems to be getting less popular so they will prob leave the tax alone - I hope!!!

Talking of Gordon and gold - do you know what the Brown Bottom is???

I was aware that the auction of OUR gold happened at a 20-year low, but I didn't realise that lovely phrase resulted from the debacle until I googled it just now!

20mpg ?? I used to use a LWB defender V8 at work and it did about 12mpg . That was the old 3.5 maybe the newer motors are better .

Send Mark Halliday a PM, he runs one.

I remember when he brought it he did some quite indepth calcs surrounding the fact he only does about 2.5K miles a year and should break even against the purchase price of a diesel in about 10 years!

I've done some rough work looking at a 4.7V8 landcruiser instead of a 4.2TD, and at 16K miles a year will catch up on overall cost at @3years

I guess what you're saying is the lower price of a petrol Disco against the higher purchase price of the Diesel. Yes?

I've had 2 v8 Rangies. The 3.5 got as much as 19mpg on the motorway and 12-14 pulling a transit van the length of the country. The other was a 3.9lt and did 18mpg on the motorway and about the same as the 3.5 when towing. I guess the 4lt will be about the same as these two. I actually found the v8 not to be a great engine for towing. It needs to be revved to produce power. The 3.9 auto also changed up a gear at about 50mph but if on even a slight upward incline and towing it couldn't sustain that gear and changed down again only to accelerate and do it over again...and again.

That's why you change gear manually with an auto box when towing............

Yup. I learnt that the hard way and it was going down hill. Dropped about 3000 ft. in 5 miles with a heavy camping trailer, and only used the brakes. Well they burnt out and boiled. New pads, new fluid etc. etc. Won't do that again.

back to certification of LPG installations for a moment...

Legally I guess you do what you want with your own vehicle within the construction and use laws, but insuring, and then years down the line selling the vehicle may prove impossible without the certificate: http://www.boostlpg.co.uk/driver_industry/Insurance.htm

An easy comment, Codders but consider it carefully and then explain how that will work.

You've turned into a bit of a doom and gloom merchant recently Richard.

Smile!

I have always driven autos like a clutchless manual. When you are driving fast on a roundabout in the wet the last thing you want is the engine to change gear when you don't want it to. Same goes for towing. You just lock the box down a gear or 2 to stop it hunting.

Going down hills again you change down to give some engine braking but it is less than a manual.
