Have been using Cerma engine & fuel treatment in my wife's 2017 Equinox. It had 30,000 miles when purchased. I have noticed better acceleration when merging onto the interstate. This vehicle has the 2.4L 4 cylinder engine which is somewhat under powered. We typically keep a vehicle for 8-10 years so I use Cerma oil, gas, & transmission treatments to reduce friction, heat, wear, & deposits. The GDI fuel injection systems are famous for problems with carbon deposits on the intake valves and cylinder heads. The life of the transmission should be extended from less wear.
