ExxonMobil said today that its Mobil SHCTM Gear 320 WT advanced turbine gear oil has been approved by GE for use in all of its wind turbines worldwide. This approval applies to all of the more than 50,000 GE wind turbines in operation today.

GE’s lubricant approval process is one of the industry’s most demanding and includes more than 300 itemized testing parameters built around ASTM, DIN and GE specifications. To obtain this approval, Mobil SHC Gear 320 WT gear oil underwent more than two years of field trials and inspections.

The approval follows ExxonMobil’s recent extension of Mobil SHC Gear 320 WT gear oil’s warranty from seven years to 10 years, which represents one of the longest warranties on the market. Any wind turbine operator who uses this product can now take advantage of this extended warranty protection.

“GE’s approval is a testament to the performance of Mobil SHC Gear 320 WT gear oil – GE is one of the top three turbine manufacturers in the world and they have one of the most stringent lubricant standards in the industry,” said Mike Galloway, industrial equipment builder engineer at ExxonMobil. “Backed by our industry-leading warranty, operators can rest easy knowing that this oil can help protect against the extreme conditions wind turbines face all around the world, helping them achieve their long-term reliability and productivity goals.”

Mobil SHC Gear 320 WT was developed in collaboration with leading global original equipment manufacturers and features a proprietary additive technology designed to provide excellent protection against common types of wear such as scuffing and micro-pitting fatigue. The oil also does not contribute to white etching cracks, which are costly to repair.
