City once again appear to be heading towards an early exit from the competition after a dreadful sequence of results.
Wednesday's shock loss to CSKA Moscow left them bottom of their group with just two points from four games and facing failure to reach the knockout stages for a third time in four seasons.
The lack of progress in the Champions League has led to speculation that some of their stars may seek a move for a shot at glory elsewhere.
But Aguero, one of their most prized assets, is determined to take City all the way.
The Argentinian, who signed a new five-year contract in the summer, said: "Not only will I stay the four (remaining) years to make it eight here in total, I'll stay beyond that - until we win it."
Aguero feels it is too easy to point the blame at manager Manuel Pellegrini for the club's underwhelming performances in Europe this season.
City had hoped to build on the progress of last term, when they reached the last 16 for the first time, but they have struggled in a group that also includes Bayern Munich and Roma.
With the side also failing to hit their stride in the Barclays Premier League, Pellegrini has attracted criticism, particularly for his apparent refusal to vary tactics.
But Aguero, speaking at the launch of his autobiography 'Born to Rise - My Story', says everyone must take responsibility.
The 26-year-old said: "It's easy for everyone to suddenly decide it's the man at the helm who is to blame, but I would say in situations like this, when we haven't played well as a group, we are all in it together.
"It is not just the manager, and not just the players - we are all to blame as a group and we need to work our way out of this situation as a group.
"I have spent a lot of years in football and am aware that these things can happen - you get bad runs - and I am also aware that you work your way out of those bad runs and come out the other side positively."
City will be eliminated from the Champions League if they fail to beat Munich in their next match and there is a winner in the simultaneous clash between CSKA and Roma.
Even if they stay alive the task remains a tough one, but Aguero has not given up hope that the situation can be turned around.
He said: "The Champions League group table is not where we want to be, and not what we would have expected.
"But, despite all that, and despite playing four games and not picking up one single victory, with the two that remain we could still do enough to be able to put things right by qualifying if we win our two games.
"But none of the games have been the real City and I guess that if we don't turn it around in these last two games you would consider it to be the worst Champions League campaign the club has had."
