Powered by CFM LEAP 1-C engines, the first Chinese-built large passenger aircraft to enter the market, the COMAC C919, used Mobil Jet^™ Oil II synthetic gas turbine lubricant for its initial test flight on May 5. The 79-minute flight took off from Shanghai Pudong International Airport.

On May 28, the Irkut MC-21 300 also used ExxonMobil lubricants for its initial test flight, which took off from the Irkutsk Aviation Plant, located in the Siberian city of Irkutsk, Oblast, and spanned 30 minutes at an altitude over 3,000 feet. The aircraft’s Pratt & Whitney PW1400G-JM engine was lubricated with Mobil Jet Oil II and its hydraulic system was filled with Exxon HyJet^™ IV-A^plus.
