I'm sure there are others using different oils in their NOX's 1.5T however, my buddy is using 0W20 in his 2018 1.5T NOX in our WNY seasons without issues or noises. Keep in mind that 0W20 motor oil are built(if you will) very, very well today. They're not 0W20's from years ago.
ATMOF, the 1.5T is a very quiet engine & excellent fuel economy(when driven like a human being) and the Equinox's since 2010 & the 2018 redesign, have been one of, if not my favorite in this segment for its everydayness, quiet & comfortable interior, absorbent ride quality and general feel.
I like the GM's(Equinox/Terrain) for their everyday normalness, rather than their ultimate(or not) capabilities, the way the Forester, CR-V & CX-5 are. The Equinox is just an easy CUV to live with.
Good Luck with your new NOX
