I’ve been flying the PA-28 for couple of days on a multi-leg flight with AP+, i noticed 4 times the fuel has remained the same since take-off or decreased slightly (most legs are 3+ hours), but today was the first time i noticed it has given me more fuel than can be loaded, normally full tanks is 0447 endurance, i took off with full tanks, when i got turned AP+ back on, it gave me 0520 endurance and 114% fuel with mixture full rich. I have seen reports of decreased fuel burn with AP+ but im not sure if adding additional fuel has been noted. ( the gauges on PA-28 show 15gal each side).
