Relegated Rangers are unbeaten so far this season but next up face tough back-to-back road trips to Bolton and Leeds.
Midffielder O'Neil, who joined the Hoops from West Ham earlier this month, told the club website: "When teams come to Loftus Road perhaps we are seen as a big scalp with teams sometimes performing above where they normally would.
"We had it at West Ham, our home form really struggled in the Championship and our away form was much better with less pressure of teams coming at us.
"We go into each match looking to win. Bolton and Leeds are going to be tough ones but if we have a fully-fit squad available we go into every game with a decent chance."
