I put £20 in the other day & only got around 20 miles, correct me if I'm wrong but shouldn't I be getting more that that?

Are you saying you were empty and put in £20 of fuel and then run it to empty 20 miles later ?

You need to clarify how you measured the quantity against the distance.

Re: 4.4 V8 poor fuel economy

It sounds like the fuel gauge is dicky. I put £20 in yesterday to an empty tank and it showed a range of 452 miles, or a prediction of nearly 100mpg! But I know that my fuel senders are up the spout and in need of attention. 2019 Range Rover P400e

2003 Range Rover Autobiography 4.4 V8 Java Black

Once I get it on the road properly I can then fill up to the brim & see what I'm getting. I did have an ambient temp sensor fault, checked it out & for some reason it was unplugged. I've connected it back up & now the car doesn't think its -40c outside I have ran it a little & seems to be better than before, could the temp sensor have caused an economy issue if it thinks it's -40c outside as trying to warm up the engine? 2004 RR 4.4 V8 Autobiography
