PROBLEM TO BE SOLVED: To provide an additive which modifies the temperature behavior of a noncrosslinkable organic medium such as an engine oil or a gear oil in uses at a temperature as high as at least about 100°C. SOLUTION: Rubber particles (crosslinked microgel) obtained by crosslinking a rubber such as polybutadiene, polyisoprene, styrene/butadiene rubber, acrylate rubber, acrylonitrile/butadiene rubber, an ethylene/vinyl acetate copolymer, polychloroprene, or epoxidized natural rubber are used as an additive for a noncrosslinkable organic medium such as an engine oil, a gear oil, a hydraulic fluid, or a compressor oil.
