Any additive added to the fuel will enter the engine via the fuel injection system where it will be burnt. If it removes any deposits there are only 3 routes for exit. One is the exhaust, then there is the engine breathing system and thirdly it ends up in the lube oil . And if you have one of the more modern engines fitted with an exhaust filter I would guess it may get caught in there.
Is this the reason its a good idea to swap the fuel filter on dervs pretty regular?
