As good as OE for less $$
A much more cost effective ATF for Subaru owners. Same as OE Subaru as far as I understand...

Idemitsu ATF Type HP
I used this fluid for a transmission service where the vehicle called for Type HP fluid. Shifting felt smooth afterward and I did not notice any leaks or issues. The fluid looked clean and poured easily. It is also significantly less expensive than buying OEM fluid directly from the dealer.

I only use Subaru Transmission Fluid
The automatic transmission from Subaru works much better than off-brand fluid.

Subaru OEM for Half the Price
I'm not sure why Subaru feels that its necessary to rebrand something a double the price, but that's exactly what they do with this ATF. Ignore the Subaru branded stuff you get at the "stealership" and just buy this. Its literally the same stuff in a different bottle. Speaking to the fluid specifically, I try to cycle 4 quarts through my Forester every other oil change and paying Subaru's prices would make that borderline prohibitively expense. This stuff is fine to use (the owner's manual specifically mentions it) and it is identical to the OEM fluid. I've heard good things about the Valvoline brand synthetic fluid, but I'm paranoid about using something that Subaru doesn't specially recommend since their vehicles are kind of "picky" about things like that, and I've noticed improved shifting after every cycle of this ATF. Is it the best? Probably not, but it seems to be getting the job done, is covered by the manual, and isn't too expense. Would recommend.
