disco average mpg

just doing some sums to see if we can afford to run a disco and need some
help.
if we get a 300tdi manual diesel, no aircon and driven carefully what mpg
roughly can i get in these condition's-
40% city driving
50% dual carriageway
10% motorway

i am working on 27mpg. is that a realistic figure?

Yup.

Mine's a 300Tdi '97 manual 3 door, we get about 30-32 mpg on long runs,
drops to about 28-30 mpg 'normal' use around local area and drops to about
26-28 towing the caravan, fully loaded with kids and about 400 kilos of
gear. We don't, howver, do much city or town driving though, except when
passing through .. .

In reality we get anywhere from 420 to 350 miles to a tankfull, but we
mostly fill it or look for a station at 1/4 full or less. It really doesn't
seem to matter what we do with it, the fuel consumption overall hardly
varies. The only time we get low mpg figures is when using low box
off-roading, and once when towing 2 horses and their horse box from Wales to
Doncaster against the wind, when the mpg dropped to 24 ish mpg.

Paul Hi,

the four years fuel consumption data for my 1994 model year 200Tdi Discovery
five door vehicle is 13.7 litres per 100 Km.

BUT it is a Camel Trophy vehicle weighting 2800 kilos (instead of the 2000
kilos that civilian Discos weight), has a HUGE roofrack with four rooflights
and a huge plaque at the front and rear, plus webbing, a huge bullbar with
two more lights mounted at the front and also relatively taller 7.00 X 16
tyres instead of the factory specified 205 X 16.

So this fuel consumption average may not reflect the true value for civilian
specs Discos.

Take care

I reckon. You might get it slightly better than that - I think ours is
averaging about 30 now, after a bit of tweaking and fettling.

Tyres tend to be on the pricey side compared to ordinary saloons - Just paid
310 for a set of 4 for mine. most of the ordinary run-of-the-mill spares
are available cheap, though, and the insurance is not too bad either.

I get more than 30 from the old 200Tdi. Long trips only, mainly main roads.
They have the aerodynamics of a filing cabinet so over 70mph I guess the mpg
will drop a lot.

What tyres did you get Austin? On your advice I just got the Pirellis and
they were only 120 for two. They're very good so far.

I get about 23mpg from mine. With the aircon switched off mostly.
It doesn't seem to make much difference on how I drive, but its mostly
nailed.
I havent the patience to drive it economically for 400 miles.

My 12litre 380hp 38t truck gives 9.87mpg every week, by the time I've
finished driving that every day I relish every mile travelled at over
55mph so the poor Disco gets a bit hammered.

I once tortured ours into returning about 22mpg, but that was hammering up
the M6 foot-to-the floor into a gale.

actually, that's pretty bloody good for a 38T wagon. Not that long ago they
were doing well if they got 7 mpg. How much of the mileage is full-weight?

I was taking into account the stated driving pattern - if you drive it hard,
you'll not get so much.

There are however badly tuned ones out there - ours now gives more economy
and better performance than when we bought it - and I had it performing
better still a bit back, without apparently hurting the mpg; but it was just
a bit smoky, so I've backed it off a tad again.


Apart from the obvious, checking the valve clearances frequently helps; the
EGR thing can misbehave and TBH is better off blanked off providing it
passes the test like that, the intercooler can get full of crud which
restricts it (next thing to play with, on ours, in fact).

Also, some of them seem to be set a bit "slow" on the injection pump, which
makes for a nice clean exhaust but no performance, and the pump timing can
usefully be advanced a bit from the book figure, IME.

P> i am working on 27mpg. is that a realistic figure?

Hello, Paul!

Posted the same sort of question here about a year ago - and I'm now happy
to reciprocate

In a year of varied driving just over 23mpg.
However the main journeys are her commutes of just a few miles to work and
back (and home for lunch)
Only a few miles and through the lanes hardly sees top gear.

On a run, can get up to 28mpg.
With the Horse Box - It's not cheap - dropped to around 21mpg

Hope this helps

Buy one anyway - you'll love it!!


Not so Clever Trevor.

G'day Paul....

I gotta 1997 Defender 110 TDi300
Just completed 3500kms down through NSW and west to east through Victoria
.. Mountains, plains, traffic, speedlimit on highways ( 110kph) , Cities, 2
wheel dirt roads, rain and shine. ... My wife and self, Loaded to the
gunnels with camping gear, food, water, fuel etc. Kept accurate records
from _all_ refills and finally filled at station near home on return.

Quite confident in average ( for _my_ vehicle) was 28.9 mpg. .... so I
reckon 27mpg for yours would be pretty close to the mark!

..... frodo.

Our 1991 200 Tdi Disco only has about 85,000 miles on it and with a
mixed ratio of mainly country road driving, a few long blasts down the
motorway and the very occasional trailer and light off road work it's
averaged just a tad under 30 mpg over all. If one really tries to
economise, using the sort of techniques they used to employ in the Mobil
Economy Run (Showing my age), we can get 34 mpg

paul .
you should get between 26 and 36mpg , the higher figure will require
you driving at 50mph as this speed in 5th gear is when the turbo isnt
under much load and not adding a lot of extra fuel .

another factor depends on what tyres youre vehicle has fitted and what
diameter they are compared to normal fitment tyres .

a vehicle fitted with 205x16 tyres will show higher MPG than one fitted
with say 7.50x16 tyres .

i think the standard tyres for a discovery are 235x75x16 and with these
youll get correct mileage figures and speedo readings ..

some owners fit different sized tyres and then this will alter readings
from the oddometer in one way or other .

with the 300tdi , when the turbo starts pulling it adds extra fuel
along with normal injection and this can have a marked effect on fuel
comsumption if you drive with the turbo pulling hard all the time .
if you keep the revs lower and drive at around 50-55mph thats when you
see best mileage figures .

some people play around with the fuel metering levels on the injector
pump and if yours has been turned up to increase power it will reduce
fuel economy .

on my 300tdi i backed off the fuel metering and gained an extra 4mpg ,
i have the metering set a little low as it wont accelerate at low
speeds [below 25mph] ] in 5th anymore and i have to drop gears but i
have no black smoke out of exhaust even when floored in 5th gear going
uphill .

the turbo fuel metering can be adjusted by rotating the diaphragm at
top of injector pump and the fuel metering can be altered by a screw at
rear of pump .

it is unlikely youll need to adjust the fuel metering unless you have
serious problems left you by previous owners attempts at a performance
diesel tuneup for all out power .

to measure fuel economy easily use a GPS and check youre speedo against
it over a short trip , say 10 miles or 100miles , then you can
determine how much the speedo is out by and work out a correction
factor if youre speedo is out a little .

on a trip to work with mine i have say 10.2miles reading on the speedo
and 10.9 miles on GPS track , approx 7% lower mileage on oddometer than
ive actually done , hence i have to add 7% to my oddometer readings
when calculating MPG figures .


i use non std 7.50x16 tyres and they are mud terrain type with new
tread and somewhat larger in diameter than original tyres were that
were fitted .

Driving in bare feet was one I remember... No coasting was allowed, and it
was all down to sensitive use of the throttle. Decent burst up to cruising
speed, then backing off the the minimum possible setting to maintain it.

or people setting it so bloody low that it won't pull off without stalling
unless you rev the nuts off it.

Which is about what ours was like. I don't expect to stall diesels on the
flat.

During the Mobil Economy runs, I think they used to do Lands End to
John'o'Groats if my memory serves me? They used to get remarkable mpg's
such as 50 mpg from things like Zephyr 6's (6 cylinder 2.6 litre cars
that typically returned about 26 mpg) with a crew of two and lots of
interesting non standard gauges and controls that would have included a
vacuum gauge.

Essentially it was just about driving with the utmost care to minimise
sucking fuel, such as avoiding braking and accelerating! Using motion
inertia by finding that perfect balance between momentum and throttle,
ensuring the vehicle is tuned and as smooth running as possible, tyres
at optimum inflation. The vacuum gauge was the crucial fuel flow
indicator in those carburettor days. I fitted one to a Ford Corsair GT
in 1967 and wondered at the huge change in fuel flow that could be made
by the smallest change in throttle without noticeable difference to
speed. Using such driving techniques I once returned 56 mpg, two up with
luggage, from London to Poole in a 14 year old Morris 1000 at reasonable
cruising speeds (speedo indicated 70 on the M3)

When I bought my Disco (200tdi) with 114K on the clock and full history
I filled the tank to work out what I was getting to the gallon and it worked
out at exactly 30.9 MPG which was mixed motoring on A roads and around town.
I expect that if I am doing a steady 56 (yeah right) it just might return
somewhere in the reigion of 38-40 mpg? who knows...

about what we get from the 300 TDi after tuning it nicely. I dunno about
the steady 56, never seem to do that
