I'm bring my syncro to Baja for the month of April and have heard that the
only unleaded gas available is 91 octane.  If this is really the only octane
available, it seems like I should tank up on 91 in  the states and get the
timing & tune redone (I use 87/89 now).  Am I correct?  It seems like I
would need to adjust the detonation for the van to run smoothly on 91.

Thanks much.
