Maybe and maybe not. On a very, very cold day or if you make a bunch of
short trips, the cat will run cold and can accumulate SOx. Then, when the
weather warms up or you are on a longer trip and the cat is really working
hard and starts releasing the SOx as H2S and SO3 AND you get downwind of the
exhaust, there it is! Until all of the SOx is out of the gasoline, it can
happen.

The gas you got may or may not have been high in SOx. It could have been,
or conditions were just right for the cat to adsorb more SOx then normal and
then desorbed it as you caught a whiff.

**** happens.

[Following other replies.]

I moved from a pretty dusty area to a clean area--then noticed the same
thing. I thought it was the heater core at first. It went away when I closed
the outside vents. In the end I decided it was the exhaust from other cars.

I've been told it's worst when people mix brands of gas on a 1/2 full tank.

I live in central Ohio and the ONLY time I have EVER smelled that rotten eggs
was when I was behind an older GM car.
At the time I enquired about that oddity, I was told it was because GM used a
"bead" type catalyst rather than Ford's "honeycomb"

We used to have a carbureted car that had a cat, it would smell like
sulphur when it was new. Went away the older it got.

I usually smell it on the freeway when driving behind newer cars that
are driving spirited. This would match the description someone else
gave, the heat is burning off the polution in the cats that accumulate
under cold/slow driving.

Question is; why do you smell it in your own car ? That doesnt' sound
healthy, it would mean there's somehow exhaust comign into the cabin.
Maybe have the trunks closing mechasnism checked out ?

I like Chevron and BP/Amoco. The "big three" like Chevron, too.

Yes and no. I have a buddy working at the port. If company A runs out,
they'll call company B and have a few of their trucks load up there.
Next week, the situation may be reversed. What makes the difference is
the additives each brand puts in after the truck is loaded with gas.

Case in point about 6 months back here in the Tampa area a batch of gas
was unloaded and sold that had way too much sulfur in it. Causing
sensors in gas tanks to go bad. The gas all came from one refinery in
the same tanker but was sold by at least two (Shell & BP) if not more
brands. **** hit the fan and the oil companies ended up paying for
repairs on the cars affected.

I use either Citgo or Chevron and have had no issues whatsoever with
any of our vehicles. Now if I use Racetrack, gas mileage goes down in
any of our vehicles we put it in to.

I've tried BP and Shell but they are generally $0.05 to $0.10 per
gallon higher than Citgo and Chevron. We are getting a BP down the
street. Maybe that one will be at a par pricewise with the local Citgo
and Chevron stations.
