Default Fluids, fluids, fluids...

So I have had my WRX for well over a year and have been on this site for well over a year. I keep wanting to change various fluids but hear this and that about all the options.

I am in college with a DD WRX, I am simply looking for what will work. It becomes impossible to choose when you hear all the good and bad about the options.

I am looking for:
- Coolant
- Transmission Fluid
- Differential
- Brake Fluid

I realize there are numerous pages and studies of all different variations of fluids but...I just want something that works for a spirited DD. I go on and read and hear that option A causes this problem, but option B doesn't, option C is too thin...etc etc. Its information overload! lol

Because I hear OEM has its downfalls and there isn't a Subaru dealership for miles around me.

unless you are tracking occasionally, subaru's OEM fluid is perfectly fine. The Subaru Extra-S transmission fluid is actually one of the better transmission fluids out there for your car anyway.

Here's exactly what I use:

Coolant: I buy a gallon from the Subaru dealer and a gallon of distilled water from CVS. I but the coolant conditioner from the Subaru dealer.

Brake fluid: If you are not headed for the track, it really does NOT matter. Get the cheapest dot 3 or dot 4 you can find. Use up the entire bottle.

Diff and tranny (for a manual): I use Valvoline 75W 90 non synthetic. Just under a qt for the diff. The rest of that qt and 3 more for the tranny.


There are plenty of other ways to go, but this gives you a start, anyways. It's also not all that expensive or difficult to do.

stick w/ Suby Extra-S and Suby super Coolant.

Brake fluid - Motul if you're feeling like burning cash, but really not needed

coolant- peak global, or the universal prestone. can be found everywhere.

brake fluid- castrol lma (easy to find and cheap), or order ate blue online(I really like this fluid)

tranny+diff- motul gear 300 expensive but good, if on the cheap get some non syn valvoline 75w90 (easy to find local) . Dont put mobil 1 75w90 in the tranny, its no good for our 5mt.

engine oil- castrol syntec 0w30 "german castrol", or rotella synthetic 5w40.

^^^ Yes - this is pretty much what I do too. It doesn't have to be complicated or expensive and nothing has broken in 70K miles.
