Motylgear 75W90

Motylgear 75W90



  • Specially recommended for gearboxes hard to shift and/or noisy earboxes.
  • All mechanical transmission synchronised or not synchronised gearboxes, gearbox/differential, transfer gearbox and hypoid differentials without limited slip system operating under shocks, heavy loads and low revolution speed or moderate loads and high revolution speed.


  • Standards: API GL-4 / GL-5, MIL-L 2105 D
  • Extreme pressure lubricant for an efficient anti wear protection reinforced with synthetic base stocks for a better resistance at high temperature and longer life span.
  • Stays in 90 grade after 20 hours shear test as required by SAE J306 Standard, Specially designed for racing vehicle gearboxes : Road race, rally, Endurance racing
  • Very high lubricating power which decreases friction and wear.
  • 90 grade at hot temperature to provide outstanding oil film resistance at hot temperature and/or to reduce transmission noise.
  • Fluid at low temperature to allow easier gear shifting when the gearbox is cold.
  • Less effort required on the gear lever to shift the gears.
  • Suitable for any type of seal and yellow material used in gearboxes design.
  • Anti-corrosion, Anti-foam.


  • Oil change: According to manufacturers’ requirements and adjust according to your own use.
