5VZ-FE engine
I've used standard Castrol 5w30 changed at 5k intervals for most of the last 235,000. No problems.

Manual Transmission
MT-90 (same)

Transfer
Redline 75w90 gear oil

Differential (looking to replace it)
Redline 75w90 gear oil

Chassis
One size fits all... Yes, you're supposed to use two different types though (moly and non-moly).

Brakes
NAPA DOT4

Clutch line
NAPA DOT4

Steering
Use Dextron type ATF, as it says in the owners manual and right on the cap. Sometimes I use synthetic on my wheeler, but I don't know if I've ever even replaced the PS fluid on my T.
