That Egg Fart Smell

[carlo]

The egg smell is from the sulfer used in the fuel.

BP Ultimate & Optimax come from the same manufacturing plant. This plant uses oil from overseas which has a lower sulfer content. However Ampol & Caltex & Mobil use a local oil mix which has a higher sulfer content.. hence the eggy smell.

I heard Optimax has the highest sulphur content. The smell is sulphur dioxide and I get it after a spirited run in my S15. In my experience, Optimax is the smelliest. I don't think it's anything to worry about though, as Zahos said, some do it some don't.

i think its more to do witht he chemicals in your cat than actually a broken cat or your fuel... the cat's got reacting agents in it that neutralise certain gasses, I guess your one jus came with less of that...

maybe you should put it up on a hoist n punch your cat (hit da kitty hit it hit it ) and listen to see if it rattles. If it duz u'r cat guts are loose and are on the verge of goin into your resonator and possibly your muffler.

Sumhow I dun think you drive your car that violently to gut your cat... maybe its just the chemicals in your cat being wierd...
