I would say the oil looks pretty good and the Fe is not THAT high considering the driving conditions. Even comparing to the linked site, 34 ppm in almost 11K miles. Not that many cited even went 10K yet some have Fe over 50 ppm.
Feel free to try other oils - but to call this a high Fe trend seems a bit strong.
