I asked the Lincoln Mercury dealer about this and they said that for optimum performance I should use a minimum of 91 octane but that lower grades right down to 87 octane regular can be used. When octane grades lower than 91 are used, the ECC (engine control computer) will automatically detune the engine to prevent knock although you will have a slight power loss. Using an octane grade lower than 91 will not hurt the engine.
