Assuming you are using the recommended octane rating, has anyone noticed if their SAAB is particularly sensitive to certain brands of gasoline? I have a
9-5 v6, and I think it runs better on Shell....but this might be pure fantasy on my part.Rich

Taking a completely unscientific approach, I can say that my car prefers our local supermarket super unleaded. Based on doing similar journeys, driving conditions and similar styles over successive weeks on different fuels, I find I can achieve higher and more prolonged boost and Sainsbury's super unleaded. MPG is better, too.
A close second is Esso Supreme (again, a 97 UK RON fuel), then Total Excellium (I think this might be a 98 UK RON fuel), Texaco SUL and lastly Shell V-Power, with which my car misfires, gets little over base boost and fuel mileage down to around 20 MPG. Our FIAT, on the other hand loves V-Power :)

Well, I can't speak for the UK or other areas of the world, but in the all gasoline is of undefinable origins. That is, the oil companies pump gas into a shared storage pool and draw from it in equal proportions to what they put in. The only difference in gas at the pump is the additive package they add and how often and how effectively they keep the water out of their tanks at the station.
Still, people here claim religiously that their cars run better on certain brands of gas. I have my doubts since the only real difference is the octane rating and the detergents they use. As long as the octane rating is honest, that's out of the picture too. So, we're down to a difference in detergents - and if your injectors are clean, that likely does not matter either.
So, I've got my doubts :-)
