Very impressed off road but mpg poor

[davenlin]

We had a day out in Derbyshire on Sunday, did about 25 lanes and really enjoyed it the 2.0 sport did us proud, kept up with the modified discos we were out with, only let us down on the muddy stuff ( my fault for selling my mud tyres ) the only thing I am not happy with is the mpg, it's did 19 mpg and around town I am getting 14 mpg that's short trips, done a service on it filters , new plugs , brakes not binding , really don't want to get another diesel but unless I can get the mpg up a bit more I might have to any advice would be much appreciated Dave

[fudge]

may be woth changing the diff and gear box oils
other than that shove some injector cleener in it.
as well check that your front hubs are unlocked around town.

Im off today Dave, pop round and we can have a look over it!

That MPG sounds perfectly normal for a 2.0 sport. Both mine (including the current one) do that sort of MPG

[fudge]

well i sort of agree.. town i used to get 20-23 and moterway was 35+ tho (befor all the mods)

[4x4 bobby]

I get 22-24 from mine with the mods and Chrissy gets 26-28 as standard.

[davenlin]

I would not mind 20-23 around town but 14 is a bit low I was getting 16-18 out of the v6 and drove that hard , will nip down about 12 Bobby if that's ok

[fudge]

mine it was tho
some times i got pushing 40 on longer trips

[BoxCleva]

I would be fascinated to know how a truck which had a combined MPG of 23 when leaving the factory brand new arrives with you 20 years later and can almost double the MPG

[hipo1024]

I find that a flatbed can really improve your mpg a lot!

I never said you said your 40MPG was combined.

I don't care how light your right foot is a 2.0 sport can't manage 40 mpg. Can you tell me how you calculated this figure ?

[fudge]

filled my take up to the max near Edinburgh then took a 500 ish mile drive back home...
droped the tank to change the carrier when i got back. found about 20l in there (and yes i did measure it)
then did the simple maths

and i am not the only one who has had 40ish mpg out of theres
and just to add point my 2.3 super charged merc does about 40 as well. even tho the book says 35 max

[BoxCleva]

Did you remove the tank from the Merc as well ? I also struggle to believe you measured precisely how much fuel you had in your tank.

Regardless , you are deluded if you think you get 40MPG from a 2.0 .

[fudge]

the merc no, but that is mostly filled up. so i use from the top of the tank to each fill

and yes i did measure the fuel. as i was not lifting it up full of fuel so i have 4 gerry cans full of it sitting around as i fitted it.
but believe it or not. but if driven correctly and maintained right you should be able to get 35 on a motorway's i believe.
and if you look at different places some say 29 to 35 for max mpg
as mine got a service every 5k miles and that was everything... fuel/oil/air done

as well it all depends on what fuel you are using as well. since most super market fuels i found i get less mpg than a branded one, and again super is even better
and with my fronty i used to do one tank of normal, and one of super.

[BoxCleva]

You're changing your mind.

We have gone from 40MPG on a motorway to 35 MPG on a motorway

The @ 56mph consumption figures are exactly that. I.e. a constant uninterrupted 56mph , no stopping , no accelerating to move round a lorry, no slowing down for congestion and the accelerating back up to the 56mph. In other words it's nonsense and virtually unachievable.

Now, given that the 56mph figure for a 2.0 is in the low 30's MPG, and was conducted on a brand new shiny Fronty , what makes you think your 20 year jalopy with a new air filter and oil filter is capable of exceeding these figures ?

[fudge]

i am not not changing anything.
on really long trips i could push the 40 mark.. as in 300miles + and shorter ones 100miles + i was getting about 35

and remember that figure is based on the 5.13 diff not the 4.88 and running on 235/75 r15 stock tyres, not the 255/75r15's
as well i would like to point out the stock pressure for the tyres of 23psi.
thus if you add all the little things together you will find it adds up to a bigger difference. the tyre pressure being a big one
as well in 20 years the quality of fuel has gotten better.

Just my thoughts.
I have a v6 swb with a 2 inch lift 31 tyres, winch and winch bumper. I regularly go laning with Tom who has a 2.0 with the same mods. When we do the same journey ( motorway and a roads) we both get about 21 mpg tops.
That is driving like little miss daisy as Tom don't no how to put his foot down
I have also owned a 2.0 with a small lift and 31 tyres, and the best mpg figure I could get was 20 mpg. Generally it would be about 17 mpg with driving on the road and abit of laning
Your mpg sounds about right but with a good service you could achieve a few more mpg but not much.
Hope this helps

Thank you Colley.
