Can I use a higher octane than 87 in my 2018 Subaru Forrester?

Yes you can.

Same here

Why not?😁 Minimum requirement is Regular gas. They say the higher the octane the cleaner the gas. Better for engine, less junk kn it. Unless you have my Forester XT which requires premium gas😭 I cant complain. My little guy moves when needed.

I use a full up with 89 every other tank full on my 2014 forester.with 60,000 odometer runs great.
