Mobil 1 Synthetic Grease has good structural stability. The synthetic base oil used in Mobil 1 Synthetic Grease gives it good performance properties at both high and low temperatures. High structural shear stability coupled with a high performance base oil make Mobil 1 Synthetic an outstanding automotive grease.
