I had a bucket of group 4 synthetic oil left over from the race car days I’m gonna try to use up. For the first time in decades I didn’t have any gear oil for some reason. The stuff is nasty slippery and has good shock absorption or vibration damping characteristics.
Group IV base oils are made from polyalphaolefins (PAO), which are chemically engineered synthesized base oils. PAOs offer excellent stability, molecular uniformity and improved performance.
