to whine a bit more when you back off. Sounds like a slight pinion whine.

I have nearly 100,000 miles and I expect some increase in driveline noise, but my brother in law's Legacy at about the same mileage is quieter.

The Forester may be a less expensive model with less insulation, and so more sound.

Is this fairly normal with this car? The noise increases with load but not much.

I was thinking of trying Redline oil because of all the good reports I have heard.

Any comments from you long time Subie folks?

Redline will probably make it quieter for a while, but after maybe 20k miles, Redline seems to let the noise back in. Not sure why. I am going to switch back to Mobil 1 next time, the Redline isn't worth the money.

Is Mobil1 too slick for the syncros? Anyone have any experience?
