I have a 1991 defender 90 petrol with genuine 62000 miles and it does an ozone killing 10 miles per gallon and I don't know what to do any help?

Jesus sounds like you've got a leak. Even the V8s do more than that. Maybe the choke is stuck on too

There are lots of things that can affect MPG. What tyres are you running, and at what pressure? Do you have a roof rack? Do you treat the accelerator as an on/off switch? If you do suspect the engine, does it start and idle properly when warm? if not check whether or not the manual choke works properly. Then the next job would be to check the mixture setting on your carbs.

I checked the timing and the carb, but I think it might be the carb leaking.

Make sure your calculations are correct, may be just a problem with your maths

How much? Wish mine cost 60 quid to fill. I get around 450-480 miles to a tank (depending on where i drive and/or tow) but is £135 to fill.

Assuming the price of diesel you are using is at £1.48, 130 miles from £60 is 14.3 MPG. Which is slightly lower than I get from mine, but I don't do much town driving.

Which, whilst not good, is understandable, you still havent answered the questions about tyre size and pressure, driving style, roof rack or other drag inducing items and it is after all a 21 year old tratter permanently in 4 wheel drive if you are only pottering around town and doing short journeys i am not that surprised at 14-15mpg.

I used to get 11mpg driving normally from my V8, and 7mpg when I was having fun

You should expect at least 16-17mpg from the 2.5 petrol, but to be honest the best thing you could do with it would be rip it out and put a Tdi in its place

Thats almost exactly half what my 200tdi is doing.
Engine on e bay 350 quid ish, another 200/300 ish to buy all the conversion bits if you cant make them yourself.
would pay for itself pretty quick

Do 2500 miles in the tdi having spent 600 pounds on the conversion and you would have broken even, which is 50 miles a week.

No roof rack normal defender wheels with full tread and appropriate pressure, no weight in the back and it's a petrol. 2.5 l. She old but not been round the block. 5 to 10 miles a journey getting up to about 50 miles an hour.
