Hello you good Volvo drivers! I have a little problem! Every time I have fuelled with Shell petrol, the engine runs a little rough. The engine speed goes in the first course of the automatic and only when I stand up and down a little. When I filled the gasoline with additional actives, i.e. the super great petrol from Shell, the Volvo did it too. After a few days the small problem is gone again. Whether it is due to the old pins wherever possible, I don’t know. Or it is due to Shell petrol. That the Volvo engines do not like petrol from Shell. That’s what it is like. My ex-tigra only liked BP Super! What do you think?
