Looking to change gearbox and differential oil to help smooth shift at cold.
BMW state 75W 80 gearbox. 75W 140 differential
Oils changed by previous owner 11 years and circa 20 K miles ago.
Looking at previous posts and some going back several years ago and noticed some Castrol products have been replaced.
Anyone thoughts on suitable current premium oils that stand out from the crowd for smoother changes,and have experienced great results.
