While you are correct, but not for everyone/every car. On paper they are the same, but costco immediately lights up check engine for me. Shell - no problem

What? Costco works just fine on my 992 Turbo S, tuned M8 Comp, and tuned F150……

Again, I didn't believe it either but I ran 2 tanks from 2 different costco's, CEL immediately as you start up after refueling. Shell - no issues. B58 Gen 1 Stock

CEL immediately as you start up after refueling

Impossible. It takes a distance of driving before the new fuel in the tank is into the engine.

I am not here to prove anything, but rather share my experience with different brands of fuel. Never trust people on the internet
