What brand fuel do you use in your Euro?
I know there is a limited range of petrol suppliers who hold premium but I was wondering what do you guys use in your Euro's? The reason why I am asking is I changed from Mobil Premium to Shell Optimax last weekend. The car is running MUCH smoother on Shell Optimax than it ever did on the Mobil Premium, I have no idea why but I am serious, the Euro's motor is much quieter and there is more power than before I filled her up with Shell! Any ideas why? I mean they are the same Octane rating right?
Anyway I am not complaining too much, but I know what I will be using from now on :D
