Of course it would have nothing to do with the recently increased ambient air temperatures would it? I mean, it's not like it wasn't <10ºC for most of the last tank of my fuel and it's now consistently >10ºC is it?
Do you brim the tank on your cars at every fill up Tom?
No, nothing to do with the temperature seeing as it was the same day lol! I know the mpg reader isn't totally accurate, but I can't fill up after every drive obviously and for it to change by 5mpg there has to be some noticeable change occuring there.
Yes I always fill my cars to the click, with the same pump, at the same station. You're not gonna much more accurate than that.
