  • Over 100,000 MWs choose CT 320 for main drive lubrication
  • Entering 13 years of service without an oil change
  • Runs 8°C cooler than other wind gear oils, for less wear and greater efficiency.
  • Generates up to 28% less foam than competitors.
  • Resists gearbox breakdown better, meaning less downtime.
  • Offers simple maintenance and fewer technical challenges for mixed turbine fleets.
  • Gives you control over your levelized cost of energy (LCOE).
Castrol Optigear Synthetic X 320
  • Reduces gear friction by 30% more than other available wind gear oils.
  • Delivers best-in-class surface protection.
  • Provides greater gearbox breakdown resistance, for less downtime.
  • Suited for high capacity wind turbine gears• Also ideal in oil-lubricated rolling element bearings. • Significantly slows any further damage in pre-micropitted gears
Castrol Optigear Synthetic X 320 AD
  • Additive pack dosage which is added to gearbox oil Castrol Optigear Synthetic X 320 to replenish additives and ensure longer life from the oil.
  • Minimizing carbon footprint (through higher life and less related waste).
  • Reduces HSSE risk (associated with oil change).
  • Lowers LCOE.
  • Can eliminate up to two oil changes of turbine main gearbox over the turbine lifetime.

Protect your critical wind turbine components

Services designed to drive your success

Castrol does more than simply supply the lubricants. We’re committed to driving your success with a range of services for wind farm operators.


Castrol Grease Flush optimizes maintenance and enhances revenue.

As turbines age, the main bearing failure rate increases, resulting in increased downtime, lower production and added expenses – impacting LCOE.


Castrol Grease Flush service combines:

  • Superior grease from Castrol.
  • Patented bearing flushing process from ONYX InSight.
  • Monitoring and intelligence solutions.

Helps to optimize maintenance cycles and enhance your wind farm’s revenue.
