Will A MK8 VW GTI make more power by using 93 octane fuel even if the car is stock? That was the question that I wanted answered. Seeing as I have already tested my wife's 2021 Audi Q3 with the previous generation EA888 motor I figured I already knew the answer. I put it to the test though to see if I was right and to help everyone else by knowing whether you would see any power or torque gains using 93 octane fuel rather than 87 octane fuel. Enjoy!
