After the Cottagers closed in on top-flight safety with successive wins at Tottenham and over QPR, Jol's men have managed only one point from the last 12 with back-to-back defeats against Chelsea and Arsenal.
Jol, though, insists his side will be out to press on again when they travel to Everton this weekend.
"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.
Fulham have not won at Everton in any of their previous 11 visits since returning to the top flight. Jol hopes to put that record straight.
He said: "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."
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."
