Disclosed is a fuel additive which may remove varnish precursor species in a jet fuel. In particular, the fuel additive may be a multi-functional adsorbent which includes a 2-dimensional or 3-dimensional interconnected mesoporous or mixed micro-/mesoporous framework and a plurality of internal cavities formed in the mesoporous or mixed micro-/mesoporous framework and the internal cavities include charged sites to accommodate fuel contaminants for varnish formation, such as metal ions and heteroatomic contaminants. In addition, methods of preparing the multi-functional adsorbent and methods for removing varnish precursor species with the fuel additive are provided.
