The article you are referencing talks about using premium fuel in cars that were designed to operate on regular. The limited information in that article came to the conclusion that using premium in a car designed for regular provided little or no benefit as far as fuel economy or performance.
Your car was designed to run on premium. While it is true that the engine management system will be able to compensate for lower octane in most cases, it does so at the expense of fuel economy and efficiency. In other words, the car will run but not as well as it should.
Why even go down that road? There’s no benefit to it, and a real although small chance that the car may suffer.
