Has anyone here got a 4.6? and if so what would be the average mpg? is it
around 14 or less?

Whilst not having the 4.6, the word 'economy' & Rangies dont go together!

I would think ( a 3.5 does around 12-16) it would have to be less.

mmm as I thought!
I am looking for a V8 ES but people seem to be asking silly money for them
or they are bad examples when I go and see them, the amount of people who
list them on eBay as "perfect" and "all electrics work" and when you get
there they are piles of sh**!! and travelling from Anglesey to anywhere is a
pain.

There's a 4.6 Hse rangie on eBay at the moment ( lots of toys) but I'd be
looking to gas convert it - but if it's barely into double figures anyway
it's still going to be expensive.

The search for a Disco ES V8 goes on!!! what was someone saying on here
about rocking horse sh** and hens teeth?

Never been, but it does look like it could be a pain!

Are we talking about a P38? If so, as you frequent here you will know about the slipping liner problem
that affects nearly all 3.9-4.6 V8's & basically makes it scrap metal?? Not interested in a diesel?

It's like anything with any car, condition is king along with service history. I'm no expert, but with
anything Landrover make - you learn real ****ing fast!

I did not realise the slipping liner issue was so frequent!! - and I thought
it was mainly on the 4.0 and 4.6 and the 3.9 in the Disco up to 1999 was
much better.

I have a 300Tdi now but want an automatic, I think the 300 Tdi would be to
lethargic in an auto. and I was looking to get a V8 and gas convert it
(£1000) and then I'd have the 180Hp and the equivalent economy.

There are a number of V8's out there with over 100K on them without the
slipped liners, so the train of thought is to get one with the lowest miles.

is there an easy quick way to spot the onset of the liner problem, on
viewing a car especially as very often in a private sale you don't drive the
car very far.

It affects all 3.9-4.6 engines from what I see! Yes, it is common & costs a packet!

The V8 is a nice engine, but from what i see has as many problems as any other!

Well, in theory yes, but practice is never like theory!

From what I read, a good test drive whilst keeping your eye on the actual water level in the tanks etc is
a good way.

Have you tried www.rpiengineering.co.uk or maybe .com. A good (if a bit scaremongering) source of V8
info!

I'm sure one of the chaps in the know will be along shortly to blow my theory into the water!

You'd be wrong then :)

Mine (1997 RR 4.6 HSE auto) averages 17mpg, mostly on 10-mile commutes with
the odd longer trip and a fair bit of towing (1.2 tonne caravan and 2.2
tonne trialler/trailer combo) and some off-road. Best ever was 22mpg, on a
fairly leisurely solo motorway trip; worst was about 14, towing in hilly
country with a deadline to meet*. Driving style - well, I don't thrash my
vehicles any more (except the wife's Focus, which is a hoot), but I don't
hang around either. Keep it around 80 on the Mway and it'll return 18mpg.

Bigger engines aren't always less economical. The fuel management on the
4.6 is much better than on the 3.5/3.9 Efi, and way better than the 3.5's
carbs.

HTH

* A lie. The actual real worst was 6.3mpg according to the trip computer,
while checking that the woodland/quarry section of an event we had organised
was actually driveable by a road vehicle. Total distance was about ¾ mile,
so it probably wasn't representative.

Sounds OK to me, even better than the 3.9 Disco! are they a nightmare to gas
convert do you know? I know the tank would have to go in the boot due to all
the suspension "gubbins" going on underneath

90ltr "filled" torroidal with external multivalve will fit in wheel well in
boot, done 3 of these now. Problem is the electronics on the vehicle, go gas
injection if it's a later thor system with the "rams-horns" inlet manifold.
If it has the single large plenum intake, then a cheaper closed-loop vapour
system will work perfectly adequately if set up properly.
These vehicles are known to have plenty of backfire issues, most are caused
by ht leads breaking down or defective coil packs.

What sort of age are you looking at ? We got a Disco ES 3.91996/7 (I
forget!) with Gas conversion , twin belly tanks afford a fill of around 60
litres so I guess they are 40 litres each tank. Gives us around 120 miles on
gas.

From my learning from the group the slipped linners seemed to effect the 4.2
and 4.6's. I've not heard of it being an isssue on the 3.9's and this along
with the gas conversion was insrumental in my decission to purchase this one
instead of a P38a which I like the look of but there reputation proceeds
them.

On autoroutes we got 18 to 20 mpg towing a 1300 kg large caravan plus kids
and lots of 3 week holiday stuff. Consider that along with the less than
half the cost fuel and forgetting and difference in LPG / Petrol efficiency
then your looking at equivelent to 40 mpg cost wise.

We purchased the car with the conversion already fitted.

Typically we get 14 mpg. Larger engines aren't always more thirsty because
you don't have to go up and down the gears as often. Anything over 3.5
Litres and if economy is an issue then stick to diesel.

It is an issue on 3.9/4.0/4.6 in the Range Rover, but not the 3.9 in
the Discovery. This is, I am told, due to the Rangie having the ECU
programmed to keep the mix quite lean. This makes it run hotter...

Our 3..9 Discovery has twin 35 litre tanks which gives us a filling capacity
of 58-60 litres - depending on the time of year and where we go for it.
We can manage (on a good day) 130miles which is 10mpg. Our old 3.9 Range
Rover used to give 18-20mpg as does our 3.5 90.

So the Rangie ECU keeps the engine mix lean. If I took it out and inserted
it somewhere, would it do the same for me?
