In accordance with the present invention, it has been discovered that additive gels can provide additives to a functional fluid over time. In accordance with the present invention it has been discovered that an additive gel comprising i.) at least two additives selected from the group comprising detergents, dispersants, acids, bases, over based detergent, succinated polyolefins or mixtures thereof wherein the selected additives when combined form a gel; ii.) optionally at least one additive comprising viscosity modifier(s), friction modifier(s), detergent(s), cloud point depressant(s), pour point depressant(s), demulsifier(s), flow improver(s), anti static agent(s), dispersant(s), antioxidant(s), antifoam(s), corrosion/rust inhibitor(s), extreme pressure/antiwear agent(s), seal swell agent(s), lubricity aid(s), antimisting agent(s), and mixtures thereof; resulting in a controlled release gel that over time releases at least one desired additive into a functional fluid when the gel is contacted with the functional fluid. Segun la presente invencion, se ha descubierto que los geles aditivos pueden proporcionar aditivos a un fluido funcional a lo largo del tiempo. Segun la presente invencion, se ha descubierto que un gel aditivo consistente en: i.) al menos dos aditivos seleccionados entre el grupo consistente en detergentes, dispersantes, acidos, bases, detergente sobrebasado, poliolefinas succinadas o sus mezclas, donde los aditivos, al combinarse, forman un gel; ii.) eventualmente al menos un aditivo consistente en modificador(es) de la viscosidad, modificador(es) de la friccion, detergente(s), depresor(es) del punto de enturbiamiento, depresor(es) del punto de fluidez, demulsionante(s), mejorador(es) del flujo, agente(s) antiestatico(s), dispersante(s), antioxidante(s), antiespumante(s), inhibidor(es) de la corrosion/herrum-bre, agente(s) de presion extrema/antidesgaste, agente(s) de hinchamiento de sello, ayuda(s) de lubricidad, agente(s) antiempanante(s) y sus mezclas; dando lugar a un gel de liberacion controlada que libera a lo largo del tiempo al menos un aditivo deseado a un fluido funcional cuando se pone en contacto el gel con el fluido funcional.
