Obviously the KAAZ fluid is ideal. But it's also $50+ per can.

I used Castrol Hypoid-C 80W90 mineral gear oil and a bottle of Motorcraft (Ford) Friction Modifier. Works out to be around $20 per change.

KAAZ specifies mineral oil instead of synthetic. Capacity is about 1.5 qt. I changed mine every 2-3 track events and it always drained clean. If I were daily driving it, I would change it with every engine oil change.
