Default Re: Regular, Super, or Premium Fuel? Thoughts?

I used to work in oil refineries. All gasoline is refined first, then the octane and antiknock compounds are added AFTER refinment. They have special one lung test engines in the labs loaded with sensors ,called "knock engines" that they use to monitor additive results.

I have also seen several different prominent brand names of tank trucks filling up from the same storage tanks.
