Someone technically inclined jump in and answer this. Does the extra octane leave more deposits on say oil seals and valves?

I felt that smell for the first time with the A/C on today. However, it only lasted about 15 seconds and then went away. Maybe the blower draws in the smell whe it occurs, because I really don't remember ever noticing it with the heater (fan) off.

There is a TSB about this at: http://web2.airmail.net/emann/protegefaq/tsb/
2000-2003 All Models
DESCRIPTION
On some vehicles, a sulfur smell or 'rotten egg' odor may be noticed coming from the exhaust system. The odor is usually noticed after a cold start, fast idle, extended periods of idling and full throttle acceleration. Sulfur smell is not an indication of an engine concern and will not cause reduced driveability or durability of the engine or any of its emission components.
The sulfur smell or 'rotten egg' odor is caused by high amounts of sulfur in the gasoline being used in the vehicle. Sulfur is normally eliminated during the refining process, but the EPA regulation of sulfur in gasoline differs from state to state. Vehicles using fuel containing high amounts of sulfur will most likely emit sulfur smell from the exhaust system.
When high sulfur fuel is burned, there is a chemical reaction in the catalytic converter causing the sulfur to oxidize. As the vehicle is driven, the oxidizing reaction odor in the converter will decrease with mileage and age.
RECOMMENDATIONS
CAUTION: Replacing the catalytic converter will not eliminate sulfur smell and replacement will just extend the period of time needed for the converter to 'age' allowing it to reduce sulfur smell to an acceptable level.
Switch to a different brand of fuel and drive the vehicle for at least 100 miles. Monitor the decrease or increase in sulfur smell.
Do not add any type of 'fuel additive' as this could add sulfur to the fuel and cause/increase the odor.
Try to avoid extended periods of short trip driving or aggressive acceleration.
Request information from your local fuel dealers on the amounts of sulfur in their gasoline. Try to use fuel containing the lowest amounts of sulfur.
Visit the EPA and gasoline company websites to stay informed on any changes in fuel or environmental regulations. A website to check is:
www.epa.gov

ive had a MP5 since august (its now june 2nd) and never ever smelled that...that includes my normal HARD driving habits and one 2600 mile trip across the country (im about to add two more 2600 mile trips in the next month and a half)...as far as your technical question regarding higher octane causing buildups the answer is yes it does cause excesive buildup when the engine isnt designed for that octane...now if you have some performance upgrades (especially if your heavily modded) you need to up your octane but if your running a stock setup using octane higher than 87 is just a detriment to your engine and its lifespan will DEFINATLY be shortened (by how much varies)
i cant believe it took a whole page of posts before someone mentioned that rotten egg smell come from hydrogen sulfide gas (H2S)...lol

hey P5ARR,
try sunoco, they're the cleanest gas (at all octane levels) in the gta; the TSBs that are issued in the states can differ to those up here.
just my $.02
edit: on a related note, i had my first P5 for almost 2 years (july 5 01 - june 2 03) and never experienced any sulphuric odour. my new P5 (almost 100kms old!) isnt showing it at all yet.

If it changed when you went from 87 to higher octane, it's because the forumulation of the gas changed, besides the octane. You really should use 87.... find a brand that doesn't stink 
. I'm surprised it took somebody so long to post the TSB.....
