I claim:

1. A triazole compound having the formula I ##STR13## wherein X is the benzotriazole residue of formula III or IIIA ##STR14## in which R is hydrogen or methyl.

2. A composition comprising a lubricant and an effective metal deactivating or antioxidant amount of at least one compound having the formula I, as defined in claim 1.

3. A composition according to claim 2 wherein the lubricant is a mineral oil or a synthetic oil.

4. A composition according to claim 3 wherein the lubricant is a mineral oil.

5. A composition according to claim 2 wherein 0.001 to 5.0% by weight of a compound of formula I is present, based on the weight of the lubricant.

6. A composition according to claim 5 wherein 0.02 to 1.0% by weight of a compound of formula I is present, based on the weight of the lubricant.

7. A composition according to claim 2 comprising one or more further additives known to improve the operating properties of the lubricant.

8. A composition according to claim 7 wherein the further additive is one or more of a further antioxidant, a further metal deactivator, a rust inhibitor, a viscosity-index improver, a pour-point depressant, a dispersant/surfactant and an anti-wear additive.

9. A composition according to claim 8 wherein the further additive comprises a phenolic or amine-type antioxidant.

10. A composition according to claim 9 wherein the further additive is diphenylamine, octylated diphenylamine, N-phenyl-1-naphthylamine or N-(octylated-phenyl)-1-naphthylamine.
