Planning for post-holiday fluid swap extravaganza...

I'm up on jackstands in the garage and ready to go.

And yes, I've searched the forum. Over time, what with the changes in types of lubricants and brand disappearance and new brand eruptions, there are a somewhat bewildering set of recommendations for fluids.

What's the collective wisdom now?

Brake/clutch fluid: I presume still DOT4, has anyone brand loyalty?
Engine Oil: I used Mobiil 1 10W-30 before, is there some new whiz bang oil?
Trans fluid: I've not a clue
Diff fluid: Still, not a clue. Synthetics?
Power Steering: renewed two years ago following leak repair during coolant system rebuild..should be okay, right?
And I'll probably flush and re-do the coolant. Last time I used Peak European spec. Anything new, anything to avoid?

And of course a couple other questons:

And as long as I'm under there, are there any telltale signs of incipient problems with bushings/guibo/etc. other than the obvious cracking and such?

LED bulbs were all the rage a couple of years ago on this board. Now, crickets. Have we ever settled on brand/numbers of LED replacement headlight bulbs and such? As long as I've got it up in the air, I'd like to update before roadstering season begins April 1.

I appreciate your advice, happy holidays.

First off, if you haven't already, I'd recommend reading Mike Miller's Lifetime Maintenance schedule (easy to find with Google). He's got great info on brands, weights, etc. and justifications for each. Based mostly on his recommendations and other peoples experiences, I've settled on the following (disclaimer: I'm no guru):

Brake Fluid: Pentosin or ATE

Engine Oil: I use BMW brand 5W-30. I get it thru dealer (with BMW CCA discount) or online for competitive prices. I think the bottom line is that if you change it frequently (12m or 5k miles), any good synthetic will be fine. Don't forget a filter. MANN are reasonably priced and have a good rep.

Trans Fluid: assuming a manual, Red Line MTL gets high marks and many recommendations.

Diff Fluid: Red Line 75W-90 (OEM weight), some guys like thicker because of driving style, tracking, etc but that will sacrifice MPG.

Power Steering: check your cap; if ATF, then Red Line D4 ATF

Coolant: I always go with BMW brand; costs a bit more but it's not worth the risk of incompatibility to me. I've heard that Pentosin makes an equivalent and might even be the OEM to BMW.

LED's. A bunch of guys on another Z3 forum I frequent recommend VLED. They look like good quality and performance. Not the cheapest but most of the Zed-heads swear by them.

ATE, used to use Super Blue.
Now only Type 200 is available.

Any API SN ACEA A3/B3 rated oil is satisfactory, older engines should use a High Mileage oil, though I just bought Amazon brand.
The factory oil in 99 was 5W30, how ever few oils match BMW brand for viscosity.

A ZF S5D 320Z uses ATF or MTL.
I use Redline D4-ATF mixed 50/50 with Redline MTL.
Changed ~ 30K miles
For differential, Redline 75W90 or 75W140, with LSD additive.
Changed ~ 30K miles

LEDs in any position except back-up lights trip the OBC bulb out warning.
