The former Manchester City defender has enjoyed a run in the team since Harry Redknapp took over at Loftus Road and Rangers are so far unbeaten in 2013.
Redknapp takes his current side to face his former club West Ham on Saturday with the R's still two points adrift at the foot of the table.
QPR have taken four points from their last two league outings, against London rivals Chelsea and Tottenham, and Onuoha knows that the positive results must continue.
"The manager said before the game that if you keep winning it is a good feeling to have and you go into the next game always thinking about the previous one," he told QPR Player.
"We have to believe we can get something out of every game we play between now and the end of the season otherwise we will have no chance at all.
"We are in good form which makes a difference because we haven't been in good form at all this year so hopefully things will go our way."
