conservative.. 20mpg.... mine wont even do that on petrol...
Trigger, if you are going to paraphrase something I have said, please don't infer something I HAVEN'T said.....
I did NOT say, that 20mpg was 'concervative'.... I said that I got 'around' 20mpg, and then qualified by how much and in what circumstances.
What I said was 'concervative' was my comparison of gas running cost to derv running cost, which put the two within a penny a mile of each other....... that is NOT saying 20mph is 'concervative'........ nor departing into 'cloud cuckoo land'.....
.....even the cloud cuckoo land of official figures hardly tries to pretend it's that high .. dunno if the rangie is better than the discovery..

They only give one figure for the classics, where they give a range for the Disco & P38, and where they have used the same engines in the Disco, look like they have taken the lower one....
As I said, it's 'ish' and the figures can vary hugely; range on 3.9 Disco covers pretty much the entire range I've suggested I've seen from my classics, and as 'stock' the Disco has a bigger body and wider tyres...... which is sort of supported by the fact that the Rangie, with the same engines as the Disco, and the same power and gearing etc can clock an extra mph or to on top wack.
But it doesn't make a heck of a of difference either which way. Depends on what tyres you have, how, where and when you drive etc etc etc.
I am a bit of a 'tender-foot' in the 3.9, mainly becouse I am constantly conciouse of the fact that driving down the road at 60mph I'm chucking a kiddies drinks bottle full of jiuce down the things neck every minute!
I can almost SEE that fuel in my minds eye, dripping into the engine, like watching a leaking tap!
But I'm also an 'old fasioned' driver, with a very predictive driving style; I'm very light on the brakes and throttle, and steering, even though I drive Auto's,
I had an XR2, for five years, longest I've ever had a car, and the car I've cranked up most miles in. It was my Aunt's before me, she passed it on with 40K on the clock and all the bills she'd had for it. I did 80K in it during the time I had it. When I finally scrapped it, I looked at all the reciepts I had, as I'd kept them all too.
When I first got it, I had it completely serviced, and amongst the works done, it had a new set of brake pads on the front and two new tyres. I never changed the brake pads again, nor the rear tyres which were the ones it was wearing when I collected it. Fronts got changed once, at about 95K, astounding the tyre dealership who reckoned that most 'lads' barely got 12k out of them. The clutch 'went' at about 80K; and when pulled was the original item, and I'd worn the friction material paper thin. It had gone right down to the rivets, where they normally go 'pop', and beyond... I'd been so 'slight' matching the revs on changes, I'd never loaded it enough to break the friction material off them.... it had just got thinner and thinner and thinner, until there was virtually nothing left!
And that was a motor I didn't pussy foot about in..... still something of a 'legend' that I took the thing airborne off the Cock & Bear bridge in Nuneaton, just for fun...... with a police-woman in the back! (when I was young and foolish!)
Anyway, MPG figures I've got for my Rangies have been challenged many times; and yes, they probably AREN'T typical, but they are achieveable.
Bottom line is that diesel is around 105p/l LPG around 60p/l depending on local pricing. Not 'quite' the 'half price' often quoted, these days more like 40% cheaper, and you still need to factor in some unleaded for warm-up; but even so.
If you get towards top end of the 'quoted' MPG range for a Disco on Derv, you can expect to achieve towards the top end for a Rangie on Gas, (which in the lack of, we can presume wont be far off that provided for the 3.9 Disco) and the break-even will be around 18mpg on LPG..... And that I'd say is emminantly 'do-able.
