On the Nulon site 80w-90 Gearbox and diff oil is listed for both the Puma and TD5 Defender diffs. For the TD5 an option of using the SAE 90 limited slip oil is also listed. My question to all is can I use the L.S.D. oil in the Puma. Both are API GL-5 oils the later being API MT-1 limited slip and hypoid diff oil. If so this would save me buying two separate lots of oil.
