## Abstract

Alkyl-substituted bicycloalkyl ether compositions useful in the preparation of synthetic lubricant compositions are obtained by reacting an alkyl-substituted 2-norbornene with a monohydric alcohol in the presence of an acidic catalyst.

## Claims

### Claim 1

A lubricant composition comprising a major proportion of a mixture of 5- and 6-octyl bicyclo (2,2,1) heptyl tetradecyl ether.

### Claim 2

A lubricant composition comprising a major proportion of an oil of lubricating viscosity and in an amount to improve the lubricating properties thereof of an ether of the formula: ##STR6## wherein R is selected from the group consisting of hydrogen and methyl, x is an integer ranging from 4 to 18, y and z are integers ranging from 0 to 16 whose sum must be 8 to 22 and the sum of x+y+z must be 20 to 36.
