Oil/Fluid Types

[Khronik]

been checking out alot of posts about motor oil and transmission fluid changes
guessing alot of it is based on preferrence but please clarify me on these, and how much I would need for DIY

Motor Oil: Mobil1 5W-30 Synthetic (been using this) = 5quarts?
Transmission Fluid: Redline MT-90 = 3quarts?
Differential: Royal Purp or Red Line?? = ?

what have you found best results using......

the capacity is only 3 quarts+? i thought it was 4 quarts+?

I see where this has been debated over and over again. This is from an FSM. I have read that it is supposed to be 3 5/8 qts. I have read 4 1/2 qts, 4 3/8, 4 5/8, etc. Let me dig around. But a safe thing to do is start low and fill until the dip stick is satisfied.

[EDIT]
The FSM states the capacity in imperial quarts. 3 imperial quarts translates to 3.6 us quarts which is right about 3 5/8 us quarts.

Supposedly, 1990 models require:

NA: 4 3/8 us qts w/ filter, 3 7/8 w/o filter
TT: 4 5/8 us qts w/ filter, 4 1/4 w/o filter

and the 1991-1996 models require:

NA & TT: 3 5/8 us qts w/ filter, 3 1/8 w/o filter

Weight: 10w-30

So, there you have it.
---------------------------

Transmission took me slightly more than 3 us qts to fill; was dry. FSM says it requires 2.8 liters or 4 7/8 imperial pints. If you do the math:

2.8 liters = 2.96 us quarts
4 7/8 imperial pints = 2.93 us quarts

Differential should be (according to FSM) 1.5 liters or 2 5/8 imperial pints.

1.5 liters = 1.59 us quarts
2 5/8 imperial pints = 1.58 us quarts

They SHOULD be as follows: (based on '95 model)

NA: 1.3 liters or 1.37 us quarts
TT: 1.8 liters or 1.90 us quarts

What makes the transmission and differential easy is that they overflow when full.
