I could be wrong but i think its more along the lines of running it empty, not just to the light on, then fill.
Even with that in mind, my 51, 52, 54 and 08 lagunas i used to wring dry as they would last about 60 miles on warning light, never had a fuel issue, many other issues yes (but thats par for the course with renault
) but never fuel, when i picked this V70 up, it was ran down to the last 25ml, the jalopy corner garage evidently didnt want to waste any more money, this does have an issue thats sort of fuel related, i have to give it gas to start it, been a long time since ive had to do that with a car...
