I have a Peugeot Boxer based van 2.2 , year 2010. Fuel gauge seems to be pretty accurate. My question is: How far would you feel comfortable driving once the "Near-empty" warning light comes on. I know i can do at least 10 miles once this light is on, but how much further? there is an ASDA 15 miles from my house and this warning light has just come on. I can save £10 on a full tank by making it to ASDA - it is on my route anyway so no silly deviating just to save a few bob. What would you do?
