Lots of discussion about Subaru dipstick reading. Apparently on some, the tube traps oil. Here’s one guy’s solution:
"This morning, I went into the garage and pulled the dipstick. It read way over full (up into the twists of the dipstick). I wiped the stick, left it out, and went back into the house for a few minutes.
I then checked the oil again, and it read between the low and full marks. I added about a third of a quart because I’m 500-1000 miles from my next oil change and because I had a third of a quart sitting in my oil box.
So this is the drill–after car has sat a while, pull the stick, ignore the reading, wipe the stick and leave it out for 5-10 minutes, then recheck."
So there appears to be some stupidity on Subaru’s part, too.
