Fluids
So, I run all Redline as we are a dealer for them. I believe that their gearoils DO all have the friction mod. that is available separate in them already. This is the crazy thing though, after 15,000 miles I did not really like them. I could feel a lot of ring backlash. So, I switched to what they call their "shock-proof" gear oil (lt.wgth) and man do I love it. Now, if someone could help me with which brakefluid to run (currently Valvoline Synthetic) and PLEASE a good ATF fluid for our tranny, I would be saved. After 150.00 my cost worth of Redline D4 and Merc 3 mix found it to be a waste and thought I broke the car! '00 RS sedan. thanks.

consensus
Yep. I heard the 4eat is a bit funny with full synthetics. I just had the tranny flushed with regular ATF and kept that in there. Seems to work all right but man, that tranny sure does suck! Besides the interior falling apart and NO dealer/manufac. support, it is the ONE thing I hate about the car. I don't know about the rest of you with the auto, but mine seems to try to shift to 4th within 50ft or so. Coaxing a downshift makes me look like I'm trying to race the guy in the Cutless Supreme EVERY time! It's either all or nothing. I find I have to autostick the car in order to keep it in the pwrband and it sucks! I wish someone would rewrite the shift code in the ECU for these d%*n things!

has anyone tried valvoline's ATF 4x4 synthetic blend Dexron 3 in their Auto trans WRX?
I realize that though the thing holds ~10 quarts, you can really only add 4 or 5 without special equipment, so it's best to add something compatible with dino ATF Dexron 3
Any thoughts on Mobil 1 75W90 for the auto's fr and rear differentials?
I agree that factory coolant is most likely best for this radiator.

Both my dealer and their lead shop mechanic said WRX models in particular should use the factory Subaru fluid (which they sell in gallong jugs as well) and nothing else, because of this danger. Normally I would be skeptical, but the mechanic pointed out that they could actually make more money selling a brand-name fluid to customers -- they would just rather take the loss and avoid replacing radiators under warranty
For the record, I run factory subaru coolant (which is premixed 50/50 with water) + 1 jug of distilled ionized water + 1 bottle of Redline Water Wetter.

I know that this is totally a noob's question, but how else are noobs to learn if they don't ask.

Thanks!
I use Amsoil product in my WRX. The exception has been the manual transmission. I use regular dino oil as of right now. That may change in a week or so... I use their ATF for power steering fluid, 5w-30 series 3000 oil for the engine and their 75w-90 gear oil for the differential. I use the stock oem oil filter as it is inexpensive and works very well.

Anything better?
I use that Castrol Synthetic for High Mileage oil for my 94.. would there be anything better for the engine than that?
Transmission is usually done by my subaru mechanic... so i have no idea what he uses.
Coolant: cheap walmart stuff..

I use Mobil 1 synthetic all the way; 10w-30 engine, 75-90w trans and rear diff. One thing I notice though is when I'm in a stop and go traffic, I start grinding into 4th gear and sometimes in going into 1st gear too. I have to ease it into 4th but in freeway speed where I guess the transmission is getting cooled, grinding dissappears. I also use Preston pre-mixed coolant and add Royal Purple water wetter. I guess I'm just lazy.

Switch to a less slippery gear oil and you'll get rid of those grinds. There's just no reason for a modern transmission to grind when shifting.

I did my coolant change recently and used the Peak Global 50/50 premix. No compatibility issues and no need to add water. Whatever coolant you use should be phosphate and silicate free, so check carefully. You can't just use whatever is on the shelf, it may "work" in the short-term but over time may cause problems.
