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?

15 mpg to and from town and 22 mpg at 70 on a longish motorway trip. Previous cars:
S-Max 2007-2013 (only diesel I've had, good car but expensive when diesely bits go wrong, so what's the point?)
Galaxy 2001-2007
Mondeo Estate 1997-2001
Sierra Estate 1993-1997
Uno Turbo 1987 -1993
Fiesta 1984 - 1987
Fiat 127 1982 - 1984

17mpg averaged on my 4.4 no matter what combination of motorway and country roads. "On first name terms with my local Dealer......now."

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.

18,8 mpg over the last 122000 kms (equals to 15 litres per 100kms)

2005 ajv8 4.4 so far 17.9 round town and 24 on motorway runs (driver only) at 70 to 80 mph.

Good luck with solving the issue

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

I averaged 17 mpg on the 2003 4.4v8 and am now getting 18mpg from my 5.0SC
