Erich,
I happily use detergent oil if the engine has been thoroughly cleaned during full rebuild, if unknown I always use non detergent oil.
In my experience both straight 30 and 20/50 work equally well when following the above rule in both the engine and gearbox.
With reference to the rear axle, I avoid using EP oils that are labelled ‘Hypoid’ but have happily used EP oil labelled ‘Hipress’ over many years without issue. The original spec D140 also works perfectly in my experience.
My first port of call for any questions like this would be the engine (or axle) builder, their advice is key.
