Overfilling theory (input needed)

[Draigflag]

I always brim mine until you can physically see fuel sitting right by the cap itself. It says in the manual to stop after the third click, but I'm so obsessed with getting the most miles out of my tank, Im not fussed about any risks. I like being able to do 320 miles before the fuel gauge starts to drop.

You might find people that do this are the same people that drive forever once the fuel low warning light appears too, yep I'm guilty of that aswell, I generally leave it a week or so when the light pops on, some people believe that running fuel that low is bad for your car too. Like you say, there are lots of theories out there, some prove people right, some prove people wrong it all depends if you want to risk it or not. I personally don't feel there's any harm in practicing either of these methods.
