The winger's return to the starting line-up has coincided with back-to-back wins against Southampton and Sunderland this month.
Those victories have given Rangers a fighting chance of meeting Harry Redknapp's 37-point survival target, and they go to Villa Park just four behind their fourth-bottom hosts.
Hoilett told the club's official website: "At training - around the building - everyone has that extra confidence.
"It is making us work harder each day to get ourselves out of the relegation zone. Everyone has the same motive - working hard as a team to get us out of the trouble.
"We are now looking forward to the next game and keeping the run going to get the points we need to lift us up the table.
"Saturday is going to be a six-pointer. Aston Villa are in the same position that we are in. It is going to be a scrap and a really important game.
"We are back in the fray. Back-to-back wins in the last two games have got us back into the race for survival. With our remaining fixtures we have a fighting chance to stay up.
"I've looked at the remaining fixtures and it is possible. We have a run of games that we can win. We have home fixtures we can win so I am trying to remain focused and work towards that goal."
