The Gers are already 11 points clear of their most dangerous rivals at the top of the division after winning their opening 10 games in the third tier.
And Ally McCoist's full-time charges are virtual certainties to win the title and complete the second stage of 'The Journey' back to the top flight. Indeed, there is growing talk of them completing a perfect season and going the entire 2013/14 campaign without drawing or losing a single game.
Nevertheless, Mohsni is still keen for the Ibrox club to put more distance between themselves and third-placed Pars with a win on Wednesday night.
The Pars can leapfrog Ayr into second spot if they draw or win the rearranged match and the Gers defender is keen to avoid that. He said: "It will be a good game against Dunfermline. They are third in the table now so it would be good to win. If we can do that, we will put a bit of distance between us and them.
"We do not relax and take things easy even though we are ahead at the top of the league table just now. We want to do well and win in every game that we play in.
"It is nice for us to do well in the cups. We got to the final of the Ramsdens Cup last week and also won our Scottish Cup game against Airdrie on Friday night.
"But the most important thing we must do this season is win the league and promotion. We must not switch off in any game that we play in. We must focus and concentrate in every match."
Mohsni and his team-mates suffered a scare in the League One game with Brechin City at Glebe Park last month after returning to action from a two-week lay-off. Having conceded just two goals in the 10 games leading up to the Brechin match, McCoist's men let in three goals in 45 minutes and were lucky to win 4-3.
The defender does not think the Glasgow club - despite having a far bigger budget than their league rivals - can afford to take any game lightly.
He said: "The game with Brechin showed us that we have to concentrate every time we take to the field. If we don't do that then we will suffer a bad result.
"Rangers is a huge club and any defeat is unacceptable so we must try to win every game that we are involved in even if we think the result is not important.
"We still get huge crowds despite the division that we are playing in. A lot of fans come and see us every time that we play. So we have to make sure that we give our all for them.
"We are on a good run at the moment and we want to keep that going. We are confident that we can get the result we are looking for against Dunfermline on Wednesday if we play the way that we know we are capable of."
