    First you just mention oil weights and say it's ok to use those, then you say it's only ok to use the Subaru stuff. Which is it?

    Yes exactly. Only use the Subaru stuff for your diffs and tranny.

    Ah I didn't catch that. I'm a little slow.....

    I still wouldn't use anything other than the Subaru lubricants, STI or not. Subarus can get funny behaviors if you use difference lubricants.

    I will say Im running Motul and am extremely pleased with it. But i think its worth saying if your going to make a change away from OEM then be very conscious of whats going on with the car

    Was this issue ever sorted? I've just fitted an STi gearbox and transmission to my WRX and get the exact same sound as in your video, it's identical.

    Keen to find out what it was.

    I found if to be the real wheel bearing . If u fitted the tranny to the car I assume u put the wheel hubs in as well . Check the wheel bearings

    Yeah, I fitted R180 hubs as well. However before the hubs were installed I had brandnew bearings fitted.

    Interesting for you that it was a wheel bearing issue, you would think the sound would always be there, not go away when backing off or accelerating.

    Was this your car in the video? This is the video I was referring to above, my car sounds exactly the same. Whines when cruising (light throttle), goes away when accelerating or decelerating and it's road speed related (changes tone with speed and sounds the same at any given speed no matter what gear you are in).
