The Cottagers guaranteed Premier League safety with wins over Tottenham and QPR, but they have picked up only one point from their last four outings to end their chances of a top-six finish.
Successive defeats against Chelsea and Arsenal have left Fulham with little left to play for over the last four games, but Jol insists his side are motivated to end the season strongly.
"People ask me 'is it easy to inspire your players or to motivate each other?', but if you saw us play against Chelsea and Arsenal you saw that we were very dedicated and very energetic to try to get results," the Dutchman said.
Jol also revealed he had spoken at length to Steve Sidwell after he was sent off for the second time in as many matches in the 1-0 defeat to Arsenal last weekend.
Sidwell saw red twice for reckless late tackles, and Jol added: "Hopefully that won't happen again in the future. What I said to him is private.
"It is a bit of his style, but if the team suffers then there is a problem. I know players want to win the ball, but there is a different way of doing it to this and hopefully it won't happen in the future."
Fulham travel to Everton this weekend hoping to end a run of 11 matches without a victory at Goodison Park.
"For Fulham, it's not an easy ground so we have to try to do some things differently and try to come up with a result," Jol said.
Winger Damien Duff is expected to be back in contention from his thigh injury lay-off, while combative on-loan Arsenal midfielder Emmanuel Frimpong is available again after being ineligible against his parent club last weekend.
Jol added: "We will have a look again at (defender) Sascha Riether (ankle) on Friday morning and (midfielder) Mesca (Tue Na Bangna) has got a knock on his knee, so he won't be involved."
