Definitions

  • the dispersant is preferably present in the final fluid in an amount of about 1.00% to about 15.00 % by weight, more preferably from about 1.00 weight % to about 8.00 weight %, more preferably about 3-6 wt %.
  • the transmission fluid contains less than 5% poly-alpha-olefins (PAO) and is more preferably PAO free.
  • PAO poly-alpha-olefins
  • compositions of the present invention optionally, but preferably, contain a viscosity index improver (VII).
  • VI viscosity index improver
  • Preferred VIIs include, but are not limited to, olefin copolymer VIIs, polyalkylmethacrylate VIIs and styrene-maleic ester VIIs. Of these, polyalkylmethacrylate VIIs are particularly preferred.
  • the viscosity index improver is supplied in the form of a solution in an inert solvent, typically a mineral oil solvent, which usually is a severely refined mineral oil.
  • the viscosity index improver solution as received often will have a boiling point above 200°C, and a specific gravity of less than 1 at 25 °C.
