2019 Equinox fuel consumption

[Dr. Rocken]

My fuel consumption is going way up.
I was getting 22 to 28 and now I'm averaging 12 to 15 MPG.
Help any ideas?

Dr. Rocken, just joined this EQ forum today. Noticed your post, and since it is about six months ago, I'm wondering what you found to be the problem?
