The Bluebirds head to Craven Cottage looking to pick up their first away win as a Premier League club, knowing a defeat could put them in the bottom three by the end of the weekend.
Fulham currently occupy a spot in the relegation zone after taking just four points from their first five games.
Their stuttering start means Jol's position is already under scrutiny, but Mackay believes their Capital One Cup win over Everton shows the Fulham manager and squad have more than enough ability.
Mackay said: "People have an opinion in football and these days with the social media aspect it is highlighted even more.
"But Martin is an experienced manager who has a group who have just gone and beaten Everton on Tuesday night. It just shows you the strength of the team.
"They are a club who have been in the Premier League for a good number of years and they are very stable.
"I was present at a couple of games on their Europa League run. I was a guest for the games against Juventus and Rosenborg and it was a great atmosphere.
"They know exactly where they are, and invariably the fans are pretty middle of the road people in terms of their expectations, I would imagine."
While Cardiff enjoyed an eye-catching win over Manchester City just two games into their maiden Premier League season, they have now gone four matches in all competitions without tasting victory.
Mackay knows there is still plenty of football to be played, but is relishing the task of getting back to winning ways and securing a landmark victory.
"We realise it is an away game and that's tough as you have seen every week," he said.
"But we are relishing going up there even though it will be a tough task.
"I know the individual skill that at least half a dozen of their present team have got and they have five or six individual match winners and an experienced manager, so we have a task in hand but we are looking forward to it.
"Every week there is a challenge in the Premier League and there is no easy week.
"If you ever start thinking like that, then good luck, because I am not sure you will last very long.
"It's about making sure you treat everyone with the same importance and it is the same as last year.
"We go through the structure and game plan and go in with the correct attitude which we should every week."
