I've had my car for 4 months, bought new. Never had to change oil, sitting at 9.500 km. I find that its recently consumed more and more oil as i got closer to 10k. On the dipstick id say I have about 25 % left until the bottom dot.

My first service interval at dealership is at 10k km and it includes an oil change. Should I just wait? I'm taking it im next week.

This is not a good practice. New or not you should check your oil at least once a week. By the time the light comes on it may be below a quart needed. Oil not only lubricates the motor it also keeps it cool pulling away heat. If your PVC valve malfunctions or an oil filter / gasket starts to leak how would you know to start looking for something that may have gone amiss? It's simple and quick to do there really is no reason not to. Also while under the hood you could see other things that may be wrong along a hose off or whatever with topping take the time to top off the washer fluid.

When you checked the oil was the motor hot or cold? If it was hot I'd add some because hot oil expands and will read higher on the dipstick when hot. Personally, I like to check the oil on stone cold motor that has been sitting overnight. I do this for a few reasons. Aside from the fact the owners manual says to do it that way; cold oil tends to cling better to the dipstick making it easier to get a good reading. Subaru dipsticks are notorious for being hard to read in my experience. Another reason is cold oil density is higher so it will read lower than when it's hot. A number of Subaru's I've owned had a notch in the dipstick a little bit above the high level mark to show how high the oil could be when hot. I'm not sure when they removed that but my kids Forester 2001 has it (see attached) but my wife's 2013 OB does not. Maybe it's a 2.5 VS 2.0 thing I'm not sure but two of my H6 motors had it as well. In short check it again when the motor has been sitting over night if you checked when it was warm, just to get a more accurate reading. If it's between the dots you are technically okay, myself, I'd add oil but that is more to make me feel better than anything else.

The oil I use is Mobile 1 this stuff here

Mobil 1™ 0W-20 Advanced Fuel Economy | Mobil™ Motor Oils

I use this filter since I always change my own oil: WIX 57055XP:

Part Details

Every new NA motor Subaru I've owned, I do the first oil change at 1K miles (1.6K km), 3K miles (4.8K km) then 5K (8K km) and then stick to 5K intervals. It's just the way I like to do it, feel free to say "okay boomer", If the shoe fits :) Cars use to come with break in oil but not anymore.

Also when it comes to the oil light AKA "idiot light", there are two different types on our car. Subaru's now have a oil pressure and level sensors. So the light coming on looks similar but there is a slight difference in look but a big difference and how it can effect your motor. See attached.

Your car will be fine, it's what the dealer recommends so you have nothing to worry about. A lot of people would argue what I do is not needed anymore, it's just something I do that definitely won't hurt. Seems in order to get the best MPG's modern engines use lower viscosity oils and tend to have higher oil consumption between changes now.

Your car is your daily driver I assume, if you were going to auto-x it that's one thing but normal driving your will be just fine.
