Engine oil: 20w50 oil. A good brand like royal purple. I now add in a bottle of cam break in fluid as well as it contains ZDDP which our old hydraulic flat tappet cams need

Gearbox fluid as far as I understands from looking in my manual is 80w90 gear oil (I have auto so a bit different)

For the diff it's the same as the gearbox but if it's a limited slip you will need an oil with lsd additive in it.
