Re: alfa-digest V7 #958 - Gas Octane and '82 Spider

    Read the owner's manual.  The stickers inside the gas cap lid on the 
older Alfas are a bit confusing with PON and RON ratings and strange symbols 
that not longer seem to correspond to the markings on the gas pumps.
    An 82 spider should run fine on 87 octane.  My Milano Gold 2.5, my 
Alfettas, my 82, 84 and 87 spiders all do fine on 87 octane.
    The mid 89 and newer spiders with the Motronic engine do require 91 
octane.  My 91 spider owners manual requires that.  The sticker inside the 
gas cap lid says, "Premium Unleaded Gasoline Only."  I run 91 octane in my 82 
now that I have fitted it with 10:1 compression Motronic pistons.
    So if you made a typo and have a 92 spider rather than 82 as you typed, I 
suggest you either stick with 91 octane or read the owner's manual and draw 
your own conclusion.

 Hi again.  With the gas prices being as high as they are here in the Bay
 Area, CA, I had a question about gas octane.  In my 82 Spider the gas cover
 states and I should use 91 and above rated gasoline.  Is this absolutely
 neccesary or can I get away with say 89?  What are people's experiences
 with the spider and different octanes?  Thanks again
