i can confirm from experience that on a 200 tdi i can do 65 miles from the light coming on to running out of diesel , i drove past 1 garage and tried getting to my local asda to save 1p a litre and run out in between . cost me a lot more cos the guy in the garage charged me £10 for a fuel can ,rip off bastard but lucky enough i put some diesel in and she started on first turn of the key
