2017 Ford Fusion Sport
So overnight my car sat with 1/4 tank of 93 in it..winter blend sucks as it is and I often see my "minimum" value hit -1.3 or so on random cylinders under heavy boost...but today on an uphill I gave it the beans a little and saw -5.4, -3.3, -3.2, and -1.2. Needless go say I was pretty spooked. Did it just pull moisture over night with already bad winter blend? Or should I be concerned. This hasn't happened before.
