In a discussion about maintenance on my 2005 Jeep Liberty CRD, a long standing member of a forum insists that a conventional gear oil is the way to go in a differential. When pressed for reasons, he cited that conventionals last longer in diffs and Currie (the manufacturer of his axles) will void their warranty if synthetics are used.
What are the differences between the performance and protection of synthetics and conventional gear oils? Which is better or worse and why?
Please help me understand.
