Re: Fw: Exhaust

[John Courtney <dendrite@sbt.infi.net>]

Several of you have responded to my posting regarding the rotten egg smell
(which I suspected was secondary to a suphar product and a result of the
catalytic converter).  Uniformly you have all suggested that I change to a
higher octane or different station.  Here's the scoop regarding this . . .

I do not use the same stations routinely.  I rely on Amoco, Marathon, and Sunoco
for my gas.  The Octane ratings used in my care are exclusively HIGHER than
93.   I have also used Chevron with Techron x 2 over the past 2K miles.

Any new thoughts?

Thanks.

John
