  • the four essential components in the form of active chemicals are present within the hydrocarbon oil in an amount in the range of about 0.5 percent to about 19.5 percent by weight based on the total weight of the functional fluid of the invention. Accordingly, the hydrocarbon oil is present in the amount in the range of about 81.5 percent to about 99.5 percent based on the total weight of the functional fluid.
  • the four essential components of the present invention could be included by themselves or in combination with other components within a concentrate.
  • the concentrate could contain from about 1 percent to about 99 weight percent of the active chemical with the remainder of the concentrate comprising a hydrocarbon oil.
  • the hydrocarbon oil is generally present in an amount in the range of about 81.5 weight percent to about 99.5 weight percent.
  • the individual essential components of the tractor fluid are present in the following amounts: the calcium salt is present in an amount of about 0.5 weight percent to about 5.5 weight percent; the EP/antiwear agent is present in an amount of about 1 percent to about 4 weight percent; the borated epoxide is present in amount of about 0.1 percent to about 1.5 weight percent and the carboxylic solubilizer is present in the amount of about 0.1 percent to about 1 weight percent, with all of the amounts being based on parts by weight of the active chemical in the tractor fluid as a whole.
  • the calcium salt is present in an amount of about 1.41 weight percent or about 3 percent with its diluent oil.
  • the EP/antiwear agent is present in an amount of about 1.7 weight percent; the borated epoxide is present in an amount of about 0.5 weight percent and the carboxylic solubilizer is present in an amount of about 0.25 weight percent of active chemical based on the weight of the tractor fluid as a whole.
  • the actual component utilized might be a calcium sulfonate complex which has been overbased with a calcium compound and then treated with polyisobutylene succinic acid or anhydride having a molecular weight in the range of from about 700 to about 5,000.
  • the zinc dithiophosphate this component might be a mixture of zinc salts of bis(2-ethylhexyl)dithiophosphate and 2-ethylhexyl carboxylic acid treated with triphenylphosphite.
  • This salt is preferably combined with a stoichiometric excess of zinc, i.e., the salt is preferably over-zinced including about 1.2 to about 1.4 stoichiometric equivalents of zinc.
  • the borated epoxide may be a product obtained as a result of the reaction of boric acid with 1,2-epoxide containing about 16 carbon atoms.
  • the carboxylic solubilizer is the product obtained as a result of a reaction of polybutenyl succinic anhydride with N,N-diethylethanolamine at a molar ratio of about 1:2.
  • these formulations may include other components depending upon its desired end use.
