Do not read in an angry tone
How about the engineers that built the car and state in the manual that 93 is preferred and a minimum 91 is
required?
They did not say 91 is required but it is OK to use 87 if you so choose.
I am not for one second saying it will wreck the engine but if there was severe knock from using it then it a possibility.
