I've been having a problem with my car smelling like rotten eggs when I blast through gears due to bad gas (lol) stinking up the cat. Switched to 93 octane, and no stinkiness! And I did notice with the gas I was using, coupled with the cold weather, my scanguage avg MPG dropped by 1.2

Octane ratings are very different between US and Europe, and I'm sure south Africa would fall under European standards... 91 us octane is equal to 95 Ron octane.. 93 us octane is equal to 98 European octane.
