Mobilgrease XHP 221 is an extended-service lithium complex grease from the Mobilgrease XHP 220 series, built on ExxonMobil's proprietary lithium complex manufacturing technology and designed to outperform conventional greases across a wide range of applications and severe operating conditions. It combines excellent high-temperature performance with superb adhesion, structural stability, resistance to water contamination, rust and corrosion protection and a maximum recommended operating temperature of 140°C. It is the NLGI 1 grade, built on an ISO VG 220 base oil, with a dropping point of 275°C, a worked penetration of 325 (0.1 mm) and a water washout loss of 8% at 79°C. ExxonMobil recommends it for industrial and marine applications, chassis components and farm equipment, where it provides excellent low-temperature performance. The data sheet recommends it for applications requiring Fives Cincinnati P-72 and states that it meets or exceeds DIN 51825 KP1N-20. It carries no builder approval on the data sheet.
