Hi, I did not dare mention additives on this site as Volvo don`t really agree with them, I think they want you to spend your money with them ALL the time. I had a 1992 2.0 Turbo 940 Sedan with slight piston slap which was the reason that i bought it cheap. I did not really worry about the engine as over here in UK the price for a new one was £1600GBP so I went against the grain and put a tin of your STP in the engine and it ran as smooth as a nut, it made the slap almost go away. Of course being a turbo i turned up the boost and it really flew. I ran it like this for about 12 months putting STP in from time to time with no problems or smoke out the exhaust. Regards
