well like anyother engine totally depends upon the maintanance
generally are more sensative thats it i have seen an rx8 done more than 100k km and still running perfectly frm lahore to multan or gt road
so it totoally is a myth which so call experts here at pakwheels keep on saying rotary dies at 50 k km ye sit does if u dont keep changing the oil n leave engine with no option but to seal
SO TAHTS ABOUT IT
