all gasolines, the contents thereof, including octane ratings and ethanol percentages, are regulated by our federal government for defense department reasons. think about it. we can't have superior and inferior gasolines for use by the military in the event of a call to arms, foreign or domestic. and you can bet your bottom dollar that the military doesn't scrimp on quality gasoline for their vehicles. meaning that gasoline, formulated and quality controlled by the government, drawn straight from privately owned oil company storage tanks, and has had nothing added to it by any oil company, is the best.
and if any particular brand of gasoline wants to add something to the gasoline so as to legally permit their multi-hundred million dollar advertising departments with budgets amounting to, on average, about two to three ($200,000,000-$300,000,000) million per oil company per year, to claim superiority is accomplished by THEN tossing in some kind of mumbo-jumbo additive. it's as simple as that.
in the end, it's all the same gasoline with various government mandated octane ratings and ethanol percentages. and then the premium oil companies top it off with their special advertising sauce from their tanks. but the truth is that it simply can't make it better, for if it was the military would have it in their base gasoline formulation to begin with. IOW, the special sauce simply cannot make it better than the government's formulation. as the military would require it in the base gasoline to begin with!
and BTW, fun fact WRT how much our government is willing to pay for the best in military equipment and it's performance...
the price of ONE, repeat ONE, of the best bombers (although it doesn't burn gasoline) in the U.S. Air Force, the B-21, is about $700,000,000.00 dollars. so the chances that the government formulated base gasoline (i.e. the cheap stuff at the discount gas stations) is not the very best available, is practically nil.
