Would you change oil before a LONG trip?

No. Pennzoil Platinum is solid oil, and 7 - 8k miles should be perfectly fine. Plus, those highway miles are the easiest miles for your engine oil ...
... Unless fuel dilution is a concern, but you are already running a 30 grade, so you have a bit of a safety net in case the oil is getting thinner from gasoline dilution.

If your Subaru is still under warranty, change the oil. Obviously your current oil fill can go longer than 5K miles. But despite most of the comments here, since the 2015 Subarus (I had a 2015 Outback) call for 6K oil change intervals using 0w-20 oil, I'd change it before your trip. You could be 2-3K over by the time you return home.
I would change the oil, less for the peace of mind (but there is that too) than that you should get higher fuel economy with the 0W-20... not a lot higher, but enough to justify bumping up the change interval 2 months.
No turbo? Mostly highway on the trip? You should leave it be and change on your regular schedule with the extra 2,500 miles. If you decide to do a UOA when you change it in OCT, I have a feeling you'll be (pleasantly) surprised by the results.

So logical its scary.

Would you recommend to change the oil before the trip? Next fill is going to be Miles Lubricants Syn 0w-20.
Thanks in advance.
Oil changes, especially if you do it yourself, are cheap and take 30 - 45 mins. I would jack the car up , put some new oil in and a fresh oil filter. Besides, if you have lots of stop and go sightseeing or other stuff going on during the trip, the oil will take a harder hit (street driving, stop and go etc). Just change it. Enjoy the trip and stay safe. Upload pics if you see anything cool.

Another way of thinking in my mind, if could go 50/50. Longer trips allow for longer ocis. Either add the miles to this oci or change it and you can go a bit longer on the next one because you started out with a long trip.
If I was going to change oil ~ before a long trip is a good time ~ I have a Frantz Filter on my F150 5.4 so the oil looks like honey ```
Send it

Agree with this.

Agree with this.
So OP, did you end up changing or not?

Non-turbo with low miles on the clock? Wouldn't worry about it, especially with highway miles. [censored], I just did a 1.2k highway trip with my car ('14 Fusion, 2.5L non-Ecoboost) at 109k and 5k on the last VWB OC. Changed it when I got back.
