From my discussions with the Volvo service techs at my local dealership, I believe that Techron is the strongest fuel system cleaner that Volvo will advise using in the car for "over-the-counter" purchases and end-user treatments. One bottle will mix to 10 gallons of gas so you'll need to buy two of them (since our 700 series fuel tanks are a bit over 17 gallons).
I also fill up at Mobil with their premium fuel a few times a year (usually 2 or 3 tank fulls in a row). Mobil has the most "cleaners" added to their premium fuel mixture, and Amoco/BP Ultimate is the "cleanest" fuel on the market. Also, Chevron does mix a bit of Techron into their premium mixture.
Also, if you're looking to clean a lot of carbon deposits from your engine cylinders, the water sipping (aka steam cleaning) method works well. This was advised as an effective solution for removing carbon build up by the head mechanic at my dealership. Details on performing the steam cleaning operation are in the FAQ at: http://www.brickboard.com/FAQ/700-900/EngineMechanical.htm#CombustionChamberDepositRemoval
I've done this on my own vehicle and a few others with good results.
God bless,
Fitz Fitzgerald.
