Over a long-term fuel log, you'll get an accurate average by writing down exactly how much was added, but for a single tank, you have to compensate for the amount of fuel between "clicks."

Also, with such a low amount of fuel, it's extremely hard to get an accurate MPG measurement. Just an extra 0.32 gallons to make 1.5 drops it down to 41.6 mpg.
It was at the very top of the "E", as it usually is. I'm anal and make sure I fill it the exact same way each time. I do three clicks: the first, fast fill until it clicks, then I ease on the handle and let it flow slow until it clicks again, then one last easy, slow flow for the last click. It doesn't overflow, and always comes out at the very top of the "E".

But I get what you're saying though. I'll be taking a trip in a month where I'll be able to better see what type of MPG I get. I hope it's close to this good if not better!
