To properly do an complete fluid change you need to make a closed loop system that allows the CVT to pump in fresh fluid as the return line is disconnected and catching the old fluid. You can do a drain/refill, but that'll be roughly 4-5 quarts of fluid. Also, keep in mind that the engine has to be running when you check the CVT fluid level, unless you want a giant puddle of fluid on your floor when you pull the fill plug off.

In regards to fluids, OEM is never a bad bet. I'm also an AMSOIL dealer and offer CVT fluid is a premium fluid option. A few other companies are out there that offer this, but these are two that I know of that are compatible. Here is the full fluid capacity:

I think I may have asked this already but is the OEM fluid Synth? Also, have you used to Amsoil? I'm a PC so I can get it cheaper though I am no where near needing to replace yet.

Is the Amsoil the same color as the OEM?

I'm not 100% sure if the OEM fluid is synthetic, but with the disclaimer that its "lifetime" tells me it probably is. AMSOIL CVT fluid is amber in color. Subaru actually uses two different CVT fluid colors between the TR580 and TR690. One is amber, the other is blue/green.

I haven't used the AMSOIL CVT in a Subaru yet, but I have in Nissans with great results.

Thanks for answering!

Does anyone know which filter this thing uses? I saw a YT video for an older subie CVT that used one filter but when I look online at subaru parts, the filter looks like an oil filter but says it is a trans filter.

I just hit 30k and I'm toying with the idea of taking it to the dealer to have the fluid done. I'm not talking about a flush which they would charge an arm and a leg, plus a testicle too but a drain and fill.

Also thinking of doing the diffs but not by the dealer. Though I'm not sure if should do the subaru fluid or just go with a 75W-90. Can also get a 75-80 or 75-85 fluid too. Decisions, decisions...
