Synthetic wind turbine gear oil
Wind turbine power generation capacity and turbine size are both increasing, which drives wind power’s competitiveness by reducing the levelized cost of electricity. However, increasing power generation increases the loads on the gearbox and bearings, which increases the stress on the lubricants needed to protect the equipment.
Going up-tower costs your wind industry customers money. That’s why they want long-lasting gear oil that minimizes maintenance while enhancing equipment life and reliability. Lubricant manufacturers must formulate lubricants that improve gearbox reliability by providing advanced micropitting and wear protection, as well as foam performance, so your customers can extend drain intervals even in more extreme operating environments.
We can help. Our SpectraSyn Elite metallocene polyalphaolefin (mPAO) synthetic base stocks are higher performing base stocks providing a higher viscosity index (VI), excellent low-temperature performance and enhanced foam performance compared to conventional polyalphaolefin (cPAO)-based formulations. These performance advantages help formulations meet and even exceed demands for next-generation wind turbine gear oils.
Due to the advanced performance of mPAO, over 40% of the HiVis PAO market has converted to it. The initial-fill wind turbine gear oil market has essentially transitioned to mPAO-based formulations.
Initial-fill market evolution
Wind turbine gear oils have evolved from a mineral oil-based (MO) industrial gear oil, to an advanced micropitting cPAO-based wind turbine gear oil, and now to an advanced micropitting mPAO-based wind turbine gear oil tailored for extending drain intervals even in extreme operating environments. This performance difference over cPAO-based formulations is transitioning the initial-fill wind turbine gear oil market to mPAO-based formulations.

We’ve developed multiple tools for formulators to ensure proper formulation solvency:
- Co-base stock selection and treat rate
- Additive package/components selection
- Use of dispersants

As you can see, our fully formulated gear oil solution demonstrates excellent solubility after six months at ~0°C.
Additionally, we’re working with additive companies to enable formulators to capitalize on mPAO by:
- Optimizing base stock and additive compatibility
- Progressing industrial gear oil testing and industry approvals
