Abstract: A lubricating composition comprises a polyisobutylene of molecular weight between 150 and 1500 and from 0.005 to 2 per cent by weight of boron trifluoride. Other additives, e.g. natural or synthetic hydrocarbons, may be included.ALSO:A lubricating composition of improved extreme pressure characteristics comprises a polyisobutylene of molecular weight between 150 and 1500 and from 0.005 to 2 per cent by weight of boron trifluoride. The load bearing qualities are set out in a series of tests. Other additives, e.g. natural or synthetic hydrocarbons and other lubricants, may be included in the composition.
