Engine - multi-grade 20w/50 (Castrol GTX)
Automatic Transmission - Dexron type fluid (Castrol TQ Dexron O)
Final Drive - Very light bodied extreme pressure gear oil SAE 90 EP (Castrol Hypoy B)
What are the modern equivalents of these? should I use synthetic oil?
Thanks.

Hi Daniel
I would use a 10w-40 in the engine.

The best ones are the Gulf Competition, Motul 300V, Redline and Millers CFS. As a cheaper alternative the Fuchs XTR, Motul 6100 and Millers XSS are good choices.
These are good choices for the autobox

The Fuchs ATF 3000 is the basic choice (but still not a bad oil) and something like the Amsoil ATF, Redline D4, Fuchs ATF5005 or 4400 are the top choices for it.
I would use a 75w-90 in the diff

The Fuchs Syn 5, Redline GL5, Fuchs Sintofluid, Gulf and Millers CRX are the top choices, Fuchs Gear Syn is the basic option.
Synthetic oils give better protection and are more durable than mineral (including semi-synthetic) oils.
