Oil is of an extremely low octane (if used for fuel).  when the engine
starts sucking oil through the intake, it is mixed with the air fuel
mixture effectively reducing it's octane rating.  Even though you may be
running gas with a 93 rating, with enough oil you may be down to 80...
Like mixing kerosene with your gas... it lowers the octane.
