Description
Castrol Optigear EP 150 High performance gear oil ISO VG 150
Castrol Optigear™ EP is formulated with Castrol’s Microflux Trans Plastic Deformation (MFT-PD) additives and increased load carrying additives.
MFT-PD helps improve performance when operating temperature and loads reach a certain level of activation energy, by enabling the micro-smoothing of surface roughness without increasing wear. The smoothed surface delivers optimum wear protection and an extremely low coefficient of friction, especially in applications which experience extreme pressure, shock loads, vibrations or low speeds.
Application
In Optigear EP the combination of MFT-PD low friction, gear oil-CLP and GL5 – FZG “Sprungtest” performance means this product range is particularly suited for applications where boundary and mixed film lubrication conditions occur.
Specifications / Approvals
- DIN 51517-3 (CLP)
Advantages
- Very high load carrying capacity.
