Lubex MasterGear 75w/80



The Lubex MasterGear 75w/80 is a low viscosity API GL-4 gear oil designed to minimise the problems of shift baulking at low temperatures and excessive noise when the oil is hot.

Highly recommended for synchronised manual transmissions, front wheel drive transaxles gear boxes, automotive hypoid and spiral bevel axles operating at low to moderate loads.

Features & Benefits

  • Oil seal life.
  • Durable gear surface life.
  • Corrosion protection to yellow metals under both wet and dry conditions.
  • Special oxidation resistant paraffinic base oils combined with high performance extreme pressure (EP) are added to ensure long service life to transmission drive lines.
  • The “stay on” properties eliminate gear train rattle, noises and effectively quietens the transmission drive line noise tendencies under conditions of low speed high torque, high speed low torque and shock loading.
  • The foam inhibitors avoid the natural tendency to develop foam in transmissions. Foam is undesirable because it promotes ineffective gear lubrication with resultant premature wear.


  • API GL-4
  • Suitable for service fill of GMH, Ford, Daihatsu, Mazda, Mitsubishi, Nissan, Toyota and all other transmissions requiring an API GL-4 (SAE 75w/80) gear lubricant.
