I am of the belief that a good 20W-50 is better for the Rover V8 whatever the year it was made. Mine is a modern unit, i.e. it was only cast 5 years ago, but it is still of the same design and I firmly believe that it will be a little quieter, and a little smoother with the 20W-50 in it.
When my sump gasket arrives, I might try some of this and report back.

Classic XL 20W-50
Applications
Castrol Classic XL 20W-50 is a conventional multigrade engine oil of good all round performance, formulated with high quality mineral oils plus selected additives, ideally suited to older technology and classic car engines.
Castrol Classic XL 20W-50 is designed to meet the motor manufacturers' requirements for passenger cars and motorcycles running under normal service conditions, but excluding those equipped with catalytic converters.
The prime recommendation is for all pre-1980 petrol engined vehicles requiring a high quality product but with an older technology additive formulation.
