I must admit none of my Mogs have had a fuel gauge I trust.
The roadster is a novelty as when full it shows full not 3/4s.
It is then very lazy in moving for the first 100-150 miles.
Then it gets a bit faster & hits half and after that it is like Usain Bolt heading for empty.
I do what I have always done on a Morgan filled at 1/2 or 200 miles whatever comes first.
