Also, how often you should change the oil will depend on type (conventional vs. synthetic) and style of driving.

Well there's the owners manual, FSM, and Haynes, but I guess you're looking for real world experience, here's mine...
1999 SS M6 240,000 miles, daily driver and weekend drag/Autox about 20,000 miles/year.
Mobil 1 engine 5k or 8k EP
30-35k tranny M1 now redline
Dexcool/distilled mix about 2 years
Diff maybe 50k? M1 now redline.
Power steering maybe 30-35k M1 but next will be redline.
Brake and clutch ATE blue changed when dirty.

alot does depend on driving habits.
regular racing id change more frequently.
oil for me is 3k. cheap insurance. filters id go by my owners manual. if you have some type of open air intake thatll need periodic maintenance.

this is good to know, i just got my 98 z beginning of this summer and will probably put 5k a year on it, (garaged winters) and am approaching 100k miles...any other fluids/maintenance i should know about besides the list above?

I'm still not sure why some people change spark plugs based on a time interval. They don't collect moisture or degrade over time without use like fluids can.
As seldom as I drive this car, I'll probably leave those plugs in for another 15 years.
For me....
Oil- 1 time a year. Unless the car sees over 3k in a season (April till October)
Radiator flush- When I did the cam. In the next 5-7 years or until the next cam goes in.
Rear end fluid- Installed the 12 bolt, when I swapped 4.10's in, and when the rear gets 4.30's
Spark plugs change- Same time as cam, NGK's generally every 12k miles
Fuel filter- 2 years or 10k miles whichever comes first
Trans- M6 Clutch Swap time, A4 every 10k and a filter swap. Auto's are the ones IMO that should get regular changes.

It's hard to say without knowing how you use the car. I wouldn't assign specific time requirements to all of those. Some of them only need to be addressed based on mileage, as they don't "age" based on time alone. Fuel filter and spark plugs would be a good example, age alone doesn't matter. For example, you could have spark plugs that are 10 years old and are still just fine, if the car is only driven 1k miles per year.
Also, how often you should change the oil will depend on type (conventional vs. synthetic) and style of driving.

Not crazy at all. The owners manual doesn't even recommend a diff fluid change for the '99+ Torsen rears. '98 and earlier, with the Auburn/Eaton style, do mention about changing the fluid though.
My '02 still has the stock diff fluid after 101k miles. I don't race the car, it's a stock daily driver, and the rear is doing great (no abnormal noises, posi works fine, etc.).
If you plan to drive the car hard (drag/street/road racing, lots of mods with increased horsepower/torque/rpm), then I would recommend more regular changes.
Not hard at all, unless the tube fitting has become severly rusted. The other end is quick-disconnect, so that's super simple.

Bump .. I know I asked how often should I change the fluids , I pretty much got that question, now how many quarts/gal do I need for each of these changes? And would royal purple work for trans,and rear diff? Because that's wanna the only good ones we have out here at our store on base..
So how many quarts to change the following?
1)Rear differential-?
2)radiator drain-?
3)trans flush,changing filter and pan gasket too-?
And I already know about the oil so this advice will be great thanks

2) Radiator drain and refill alone will be less than 1 gallon. It's usually about 2/3 to 3/4 of a gallon when I do mine. If you want to flush the whole system, you'll need a couple gallons.
3) A complete trans system flush will require 2-3 gallons of fluid. The converter, trans case and lines all contain a lot of fluid. If you plan to do just a pan drop and filter change though, then 4 quarts should cover it.
