I always use Shell 93 in my 2019 GT. Shell 87 for my 2017 Escape. After many years of switching brands, I settled on Shell a number of years ago.
The Escape gets the best mileage with Shell out of other brands.
So I figure while I don’t care about mileage in the Mustang, the added cleaning...
When I had a 2002 GT, passenger foot well was very wet after a hard rain. Local Ford dealer eventually determined that there was no sealant for 12 inches or so on the right side of the windshield .
