Looking at some bigger 4x4's

Lots of V8's from the landrover stable going with LPG conversions


Question is are they viable, or are you still paying big fuel bills even with LPG

I did a quick calc on paper,

Petrol on a 90 litre tank returns approx 432 miles £120

LPG at 70L would return 264

so effectively I'd need 2x fills of LPG to achieve 528 miles £103

and after 4.5 fill's id be on a free 70L

Now that's on paper, what are they like in the real world

Or do the savings get mullerd?

multipoint kits are the only systems worth getting. The savings should be around 40% if fitted and working properly. Need any info pm me.

I think you need to do your sums again, it wouldn't take 4.5 fills.

Over 2 fills you save £34 and do 190 miles more. so after 4 fills you have done 380 miles more plus you saved £68 so then you get your free fill plus your 380 miles, and £17 change.

I think.

i had a 4.2ltr Range Rover - converted in 2001, and ran it on LPG for 6 years

problably went thru less than £100 worth of petrol in all that time - saved me an absolute fortune (its started and ran on LPG 100% of the time)

but I had a masshoosive 120ltr tank in the boot - and on a cool day could get over a 100tlrs in the fvcker

this gave a decent range

fuel consumption was slighlty less (10% or so)

my brother has self converted all his cars apart from his WRX (about 7 in total) and makes very good savings currently he runs a 3.9 V8 Disco

Thats what i was looking at , what MPG does he get from the LPG?

I'm seriously considering converting my BMW 530i as well..

I'm getting absolutely mullered by fuel costs at the moment, getting about 200 miles for 80-85 pound fill up, depending on what the forecourt cost is at any given day. At 1000 miles per month, my wallet is hurting.


It seems as if LPG makes sense on cars with large petrol engines. I wouldn't bother if it wasn't a large petrol engined car I liked and intended to run for a while - I've seen conversions done on things like astra's, and you'd need to do astronomical mileage for them to make sense.

LPG on my BMW would mean the difference between being able to keep it, realistically, or selling up and getting something different.

Also, there's the psychological issue of paying near as damnit 100 quid every time you go to the forecourt.

It might take a year to recoup the costs, but it will be less painful to fill up immediately, which will make a big difference psychologically IMO.

This is it in a nutshell

TheWaterboy

I ran an 80 series Landcruiser auto 4.5 petrol which had been converted with a 90 litre under slung tank. It roughly did around 15 mpg and at the time LPG was around half the cost of unleaded so in real world figures/money costs it was doing 30mpg. Compared to the 4.2 diesel Landcruiser that do no more than 20 - 22 mpg on more expensive diesel it worked out in my favour but only due to the fact that the previous owner had bore the cost! People say you loose power on LPG but I didn't notice any loss, the only drawbacks are finding LPG filling stations and the actual time they take to fill the tanks. If you register you have converted to LPG you are congestion charge exempt!

he gets roughly 150 miles to £50 woth of LPG

he lives in London so that does include a bit of town driving - which kills consumption

and as someone who ran a 4.2 V8 on LPG for 6 odd years - I totally concur with Henrik

it just takes some of the pain away - on a day to day basis (and quite nice driving it with a fuel gauge that does not visibly move when you are doing 75 on the mway

mart360

It wouldnt be on a daily basis for me ....

Weekends & trips out...

Typical, the one i had my eye on has gone, so now to keep looking,
Seen another, nut its a slightly lower spec, and i think it's single point injection (which he states is the best one lol ...(dont you just love ads!))
or look at a diesel

Similiar to my brothers - make sure you check for the "three amigos"

Very common problem and can be masked by removing the bulbs

Such a shame they did not fit the mechanical diff lock, I believe the mechanism is in the transfer box - just no way to engage it


Also check for the Porous block syndrome - I am not sure whether it effects the 3.9, it certainly effects the 4.0 4.2 and 4.6 - classic sign is the rock hard upper radiator hose when engine up to temp

mart360

Allready aware of the 3 fellows lol ....

Cheers for the heads up on the porus block, will remember that if i look

Not anymore you dont. we run 3 LPG vans which upto the start of last year were free. now they are the same as any other vehicle. The reason being that electric vehicles are MORE fuel efficient.

TheWaterboy

Doesn't really surprise me. Running LPG used to be a viable proposition but like all good things the Government catch on and take away any benefits
