ABSTRACT:
An additive concentrate has at least one nitrogen-containing deposit control additive, a solvent, and at least one tagging material. The tagging material has a number average molecular weight of at least 15,000 and a weight average to number average molecular weight ratio of less than 1.5. The tagging material has a molecular weight distribution that is sufficiently different from the molecular weight distribution of the deposit control additive so as to be distinguishable from the deposit control additive. The amount of each tagging material is less than 1 weight % of the additive concentrate.
