Re: [oletrucks] Octane inquiry/ Lead additive

[Terry White <twhite@bcbsal.org>]

Mike,

 I am not by any means trying to lead anyone to believe that I am  a
mechanic, but this is my experience.

I bought my 56 in late 95, drove it almost everyday for 3+ years using
 92 and 93 octane fuel. I was told that sooner or later if the head
did not have hardened exhaust seats I would lose compression.  Guess
what,   I did.  I have decided to put a newer model 292  because of
the lack of parts availability here in Alabama.  My advice would be to
use the highest octane you can buy, drive it till you get a noticeable
loss of power, then look at the possibility of a rebuild, chances are
if you have the head worked now it will only put higher compression on
the worn cylinders.

Just my thoughts..

                            How critical is it for these old engines
to be 
fueled with lead additives? Is the overall performance diminished if
only 
using an 87 octane with nothing added? I've been running my 235 for a
year 
now and have yet to mix anything in with a fillup. Lately I have
noticed a 
slight hint of exhaust smoke which was not the case last year. Oil is
changed 
frequently and it's been tuned up lately. Any recommendations on the
use of 
lead mixtures in the gas?   Thanks
