In 2000, Force was sponsored by BP's Castrol brand, continuing the relationship between Force and Castrol that began in 1985 and lasted through 2014. After winning his fourth Funny Car title in 1994, Force earned the nickname of "Brute Force" from drivers, and even announcers such as Steve Evans. This nickname hearkens back to his early days on the track, when he drove his own unsponsored car, named "Brute Force". Force had a cameo in a 2004 episode of "King of the Hill" ("Dale Be Not Proud"), in which Dale Gribble donates a kidney to Force, after which it appears he does not need it.
