Oil Change - First time on a subie

Looking to do an oil change for the first time ever on a Subaru. 2021 Sport 2.5. Its the second change, the first the dealership overfilled the oil and also screwed up a basic thing such as rotation. Its my wifes car, i told her i can just do it.

For the record, i am very mech inclined, wrenched all my life, but i know nothing about these engines so i thought i would just pop the question, is there anything i should be aware of doing an oil change on the crosstrek? Any weird subaru black magic that has to be performed, or just drain, change the filter, and fill?

  1. Is the drain behind the plate on the bottom?
  2. Torque spec for drain plug?
  3. Do you need ramps or jacks to reach underneath or is there enough clearance?
    1. I ask because i have a bad back and just doing homework upfront rather than crawl underneath, which is a chore for me at the moment
  4. Thanks in advance

I use ramps when doing an oil change. You'll see the drain bolt based on the cutout from the plastic cover underneath the engine which you can't miss because you'll see it as soon as you look up.

The torque spec for the plug is 30.8 lb but someone can correct me if I'm wrong. There's nothing hidden involved while doing the oil change, pretty much the same process as any car.

OK, so dont drain the cvt is the consensus.
It may sound like the tire rotation was a bigger thing than i meant. Im pretty strict on my car care, always done all of my items for all of trucks and suv's, by the book, because i know it was done right. They rotated front to back, instead of diag because they said they are directional. the G91's are not directional. Not really a big deal on a new car, i just dont like when things are presumed, thats why people hate dealerships, laziness. Really my only complaint was the overfilling of oil by over 1/2 qt. Tires was just a byproduct of my frustration.

Drain plug torque is 29 ft lbs. The drain plug is through the plastic skid plate at an angle but can be accessed without removing. Have never lifted the car to change the oil but if you are having back issues, might be good to do. Crack the filter loose and let it drain a bit so the oil does not go everywhere before fully removing. Easiest oil change of all the cars I have ever owned over the years.

I always cross tires on one end. When you have a clunky AT type tread, it is critical to even the tread wear. The outer lugs wear on the front tires so they need to be reversed to even out the wear. You cross the tires to the drive wheels. So on the Crosstrek, the rears cross to the front and the fronts go straight back.

so when you guys do your tires, what are the jack points? on the forum ive found theres a cross member behind the oil pan, and in the rear to use the differential, is that correct? That would mean placing jack stands on the pinch welds, which ive never had a good experience with

I’m a new Crosstrek owner and I plan on doing my own maintenance with the help of this forum and YouTube. One thing I got from a forum link to a YT video was how to prime the system which has an inverted oil filter. Press the accelerator to the floor and turn the key to start. The engine should not start and after a brief period, the oil light should go out indicating oil in the filter. I hope I described the procedure correctly, but it would appear to be an important step.

Consider buying a Fumoto Valve, or a Stahlbus Valve in the future (I have a Stahlbus). Change your oil with white gloves on then and in a very short time. If not Subaru is incredibly easy anyway. Don't drain the CVT. If you can see your toes while standing straight you can probably change your oil without ramps.

Fumoto:

Stahlbus:

Did we mention the CVT...don't do that.

Easy peasy.

Did my first oil change on my 2021 a couple months ago. Can’t wait to use my Fumoto valve and drain line on the next one. Especially since it’s at an angle and splashes oil from the grids on top of the oil drain tub since it’s hits them sideways instead of straight down like my 4Runner.

I did my first oil change on my (new to me) 36K 2018 6MT today. I took this opportunity to replace the drain pan bolt with a Fumoto valve. I purchased the one with the extension. It's still well above the plastic skid plate. I filled up the filter with oil to the top and let it sit while I drained the oil. This allowed it to be absorbed into the filter. When I went to install the filter, very little oil dripped out. I used the pressed accelerator (and clutch, in my case) procedure to turn the engine with the battery until the oil pressure light extinguished. I then started the engine. After a minute run, I let it sit, then checked the level. I know that I'm going to like the Fumoto, but I know I'll miss the opportunity I had today to lubricate my ratchet when I dropped it into the oil drain pan.

I’m not big on it in general, I just saw one video where a guy said the chain tensioners work from oil pressure, dont know if thats true or not. My Tacoma has an inverted filter and it’s been fine for 120000 miles with no priming, not even sure if there’s the ability to do it. But, different car.

Ill just do the procedure

I put a Fumoto on all my Scoobies, makes changing the oil a snap.

All good advice above, the only thing I'd add is before you start the car the first time, prime the oil filter. Because of it's location, up top, you can no longer pre fill it before you install it. So now you need to do this to get oil in there before you start the motor.

Push the gas pedal all the way to the floor and hold it
Turn the key / press button depending on your system - and let it crank a few seconds.
Putting you key to the floor will prevent the motor from starting it will just turn over with the starter, this will get oil in the filter.
Next release the gas pedal and start the car and check for leaks at the oil filter or at least that's what I like to do.

FWIW WIX makes very good oil filters and they have the proper bypass pressure. I've been using them for years on my Subarus and get very good results with my oil analysis. I change my oil between 4-5K. Rockauto.com has great prices I get them by the dozen. This size fits three of my 4 current Subaru's.

Thanks for the filter recommendation. Although the filter is installed inverted, I have found that I can fill the filter with oil and let it sit while I add my engine oil. By the time that’s done, the filter elements have absorbed the oil so that I can invert it for installation without losing a drop. I then follow your procedure for priming. I don’t know if my process helps, but I’m sure that it doesn’t hurt and may reduce priming time a little.
