International Aircraft Manufacturers rely on ExxonMobil lubricants for recent test flights

ExxonMobil lubricants were recently selected by international aircraft manufacturers COMAC and Irkut to support the first test flights of their respective COMAC C919 airliner and Irkut MC-21 300 aircraft. 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-Aplus. With nearly 600 million hours of on-wing experience, today Mobil Jet Oil II is used in more than 50% of aircraft in operation. Its popularity stems from its proven ability to help deliver outstanding engine cleanliness and component protection.
