I just purchased a 1993 100CSQW about a momth a go.  I am sure this
question has been addressed before, but I couldn't find it in the archives.
Is it necessary to use premium fuel (93 RON) in this V-6 engine.  Will it
cause damage to the engine?  My suspicion would be that under easy
acceleration there would not be any damage to the engine.  I suspect that
because the timing would be retarded by burning a lower octane fuel, that
the fuel economy would suffer?  How much?  I would appreciate any and all
input
