The methods and test kit of the present invention provide a fast, inexpensive, reproducible, simple, and accurate method for optimizing the dosage of an asphaltene dispersant antifouling agent for a given crude oil containing asphaltenes. A method is provided wherein a sample of the crude oil is diluted with a quantity of an aromatic organic solvent. To the diluted crude oil is added a known amount of the antifouling agent being evaluated. A portion of the diluted crude oil containing the antifouling agent is removed and mixed with a quantity of a liquid paraffinic hydrocarbon. The concentration of materials which remain dispersed in the liquid paraffinic hydrocarbon is measured. The inventive methods are useful to evaluate a single dose of an antifouling agent or may be used to simultaneously evaluate a plurality of doses in order to determine which dose is most effective for a given sample of crude oil.
