API GL-4
SAE 85w90
for Manual Gear Box
Description

SEASON GWHEEL4 is a mineral gear oil [According to base]  for axle and hypoid transmissions calling for API GL-4 performance fulfills the requirements of a mechanical transmission gearboxes with moderate "extreme pressure" characteristics and is specifically developed to avoid corrosion .Even at very low outside temperatures SEASON GWHEEL4 offers the fastest possible complete lubrication during start off, outstanding gear efficiency and lowest power losses.

Advantages
  • Multi-purpose suitability both for running in and long-term applications
  • Very good load-bearing capacity, even with high load long-term stresses and resulting high oil temperatures
  • Excellent cold-flow properties; because of this no lack of lubrication when starting off
FEATURES & BENEFITS
  • Compatible with many gasket materials and other elastomers.
  • Prevents from corrosion with many metals normally used in gearbox manufacturing
  • Effective foam control even at high engine speeds and oil temperatures
