I had a Fairey OD in my S3 LR 6 cyl for 18 years and only once did it have to have some bearings needed replacing. I originally used ordinary gearbox oil in it but after a few hours it would be nearly boiling so I used a Moreys synthetic oil with no problems. A mod was done to the OD, I forget the exact details but it allowed oil to be thrown up to the rear of the OD to lubricate the rear gears/ bearings. As the S3 came with a gearbox temp gauge the drop in the temperature was noticed when using the OD. When the 6 cyl was replaced by a 186 and higher ratio diff pinions added I could cruise at 90km with better fuel figures that the standard LR 6 could produce.
Advantage was the OD could be used on all gears and in hilly country the 3rd gear with OD was often the best gear.
