Research of usefulness of fuels for long-term storage is an important research of products of special use (meant for stock keeping as national or military reserves). Important fact is that fuels after storage should be used according to their initial use so their phisico-chemical and exploratory properties should remain the same during the whole storage cycle. Basic condition, enabling to foreseen that fuel will keep its quality at sufficient level in certain timeframe should be positive results of ageing tests. Below the doubts are presented whether methodology of evaluation is correct because of important differences in mechanisms of accelerated laboratory tests as well as real storage in typical conditions of storage tanks with large capacity. Differences in courses of chemical reactions and conditions of their initiation and course were pointed out. Scheme of equipment for marking content of existing gums, scheme of equipment for testing induction period, scheme of filtering and oxidizing equipment to test resistance of fuel to oxidation, effectiveness of collisions of molecules of reactants, scheme of chemical ageing process of fuels storaged in different temperature, function for different conditions ageing process of FAME, influence of value of potential molecules energy on initializing of chemical reactions are presented in the paper.
