My suggestion is to drain from the bottom drain hole as much as will pour out (about 3.6 quarts). Refill with Mobil 3309 in the same measured amount. Drive normally for about 100 miles.

More ideas: Pull all the spark plugs and see if any are black. Black means not firing or getting too much fuel. Check the plug gaps - need about 0.030 inches.

My 2001 V70 with Aisin AW50-50/51 automatic 5 speed had a rebuilt transmission installed at 168K miles. It was filled with Mobil...

The scale of the photo fooled me. I just looked at my 2001 V70 T5. It is a breather. The yellow cap has a little play to move up and down.
Sorry to mislead.
