Say this advertised earlier for about £100, just wondered if any has had something like it done on their car and what people thought of it. (I’m in the UK so it might be different to what you can get over seas)
Seems worth a punt for that price, thinking of getting it for my B6 S4
Probably not going to do much if you use a fuel that has detergents in it.
don’t bother…no proof it does anything yet
you don’t need it with your multi port injection B6 S4. The gasoline being injected pre cylinder results in a washing effect on the valves, so any carbon tends to get cleaned out by the engine normally
FSI or direct injection engines inject fuel in the cylinder, bypassing the valves, and the carbon build up doesn’t get touched by the fuel.
What do most people use to clean carbon off the valves on their FSI engined Audis? Gasoline.
What did Toyota do to ensure their direct injection engines didn’t experience carbon buildup? Created an injector to wash the valves with…you guessed it…gasoline.
You’re good!
Brilliant, thanks for the replies guys
