    Abstract: The use of tetrahydrobenzoxazines I wherein R1 is a hydrocarbyl radical andR2, R3, R4 and R5 are each independently hydrogen atoms, hydroxyl groups or hydrocarbyl radicals,and where R2 to R5 may also form a second and a third tetrahydrooxazine ring, with the proviso that at least one of the substituents has from 4 to 3000 carbon atoms and the remaining substituents, when they are hydrocarbyl radicals, each have from 1 to 20 carbon atoms,as antioxidants for stabilizing mineral oil products and fuels against the action of light, oxygen and heat.
