I travel pretty regularly and inevitably there is the moment on the trip where I have to refill the rental car gas. I pull into the filling station only to realize once again I didn't remember to check which side the nozzle is on. Did I get lucky on this one? Crap! Back up, Redo.

Until now....a colleague just gave me a little nugget of information that has instantly enhanced my travel life. Most modern cars apparently have a little arrow on the fuel meter indicating which side the gas cap is on.

It's amazing how this little nugget has been overlooked by so many. As I searched for an image to embed in this post I came across lots of similar posts including one by a sharp Ruby on Rails developer named Paul Gross.

I hope this odd little tip is as useful for you as apparently it has been for many of us.
