They all do that sir. My Roadster gauge is useless. I use the oddometer to judge when to fill

Whilst you might not have been able to fill it up as much as you estimated, you car is probably doing more MPG than you first thought. I find my fuel gauge can drop suddenly within a few miles, then as soon as I find a constant speed it rises again. At best the fuel gauge is an indication of some petrol in the tank, often beyond that hopeful note of optimism , I tend to rely more on the miles travelled since last fill up and my conservation MPG estimate as my more reliable gauge of remaining fuel, as I don't need the onset of remaining range anxiety.

I thought you just did or did you not note the mileage? I just fill every 200-220 miles as the avg mpg is around 29. Yours should be far higher of course.
I guess you are after the real end mileage possible, I just don't take the risk and start looking after 200 miles.

I do as John does and fill up at 200 miles knowing I probably have another 50 miles in hand at 23mpg with my 1999 Plus 8 - as the fuel tanks appear to vary if you really must know the capacity fill it up and pump it out using a small 12 volt pump and 5 gallon drums it will be the only way to know.
Most of us run on the odometer method I think you'll find.

Take out the spare wheel, accurately measure the tank and cube up it's volume, however as some have found you can't always get a Morgan tank properly full due to venting issues as you pump petrol in
