Help my Landy is drinking fuel!

Hi I have a Land Rover discovery 2 TD5 AUTO.
It has a 2 inch lift and is on insta turbo mud tyres. I had a stage 1 map according to the person I brought it from too along with a straight pipe.

It seems to be using alot of fuel. I get about 70 miles to £30 if I’m lucky. A friend of mine has driven it and says it doesn’t have the pull a TD5 auto should have but I’m not used to land rovers!

Any help would be much appreciated!! What’s your thoughts??

Land Rovers play mind games. This could be one of them.

What do you suggest to do?

The auto is more sluggish than the manual. The insa turbo tyres might also have raised the gearing depending on their size. Might also be worth checking the brakes aren’t binding or callipers sticking, which could cause an increase in fuel consumption and a lack of power.

You're a psychologist, aren't you?
If so, that's cool. We could use one around here.

But back to your question.
If you are an empirical type, I suggest burn it with fire. If you're of a more metaphysical ilk, try smudging with sage and prayerful fasting.
Welcome.

70 miles for £30 ??
16.25 liters (?)
3.5 gallons
20mpg .... I think 25 to 27mpg is about 'normal' so your 20 could be a result of the larger tyres, remap and a heavy right foot .... and/or any of the issues @Knappster mentioned.

Drive it like a grandma for the next week or two, try to not brake unless you need to stop, avoid heavy accelleration etc, cruise, it's not a hot-hatch.

Also worth giving it a service. A new fuel, oil and air filter together with an oil change works wonders.

70 miles to £30 what is that in mpg? and did you test it brim to brim?
Don't expect much more than 26 mpg, in general running around.
The lift will make little difference, but if the tyres have a muih bigger running circumference, it will.
But I would suggest you ensure the MAP/IAT sensor is good. I have only just changed mine after owning it for 8 years.the difference is incredible.
Mapping it can be a snare and a delusion. Do you have the original ECM? If so you could plug it back in and see if that makes a difference.

And don't forget the centrifugal filter!!

I put a straight pipe on mine it made feck all difference, to get more horses or torks out of the exhaust you need to change the whole system, as I did on my D1 300tdi. Where it made it far more driveable and if anything improved the Mpg!

Sounds like around 20mls to the gallon slightly thirsty but its an auto with big tyres so low 20's are probably to be expected.

Don’t mention the mpg If you bump into those Juststopoil types

This was back in July, mine was standard engine and ECU and just a straight pipe and a sticking front caliper....

They all do that sir

18mpg for my old auto Td5. Mud tyres, loads of weight etc… it’s normal sorry

I wish my series e 109 petrol was that frugal, I could use it more.

Col

Sounds about right

My V8 P38 was cheaper to run than my Auto Discovery, a depressing thing to learn when I bought it to be more frugal.. ooops.

V8 did 22mpg mixed driving and my D2 did 20 on dizzle which as we know is more expensive LOL and it was bone stock

D2 Auto with bigger tyres i'd say yours is doing about right,.

My dead stock D2 Td5 auto does about 26 mpg on average. A bit better on long runs but not much.
