Does anyone using this fuel experience any unusual smell coming from car. Guys from work that are behind me say the car really smells bad. I’ve checked on the net and it says it’s sulphur and that because our cars are high performance the fuel is putting the fuel mixture under undue stress as they were not designed to use 99 octane fuel anyone got any thoughts on this.

They require 98 octane and can adjust ignition advance to deal with 99ron, i dont beleive that would put the fuel system under stress. Your problem if it actually a problem is something else.
Mine is fine on tesco momentum. Try a different high octane fuel if it bothers you and see if that is the same.

If it smells sulphurous (rotten eggs) it’s more likely to be the cats going home, if your car has cats that is.
Unless it’s whatever Tesco use to increase the octane?
