Its all propaganda, A little Alaskan Ever Clear will go a lot further with performance.

 

I use Shell Nitrogen enhanced gasoline and swear that it gives my bike an extra 25 horsepower. Maybe 15. Okay, at least 8. Would you believe the same as any other gasoline?

 

I have checked mileage using several brands with the 06 ultra and the 2500 truck using the "same" standards. I have found that shell gas (93 OCT) gives me better mileage in both. I generally use 101 OCT Shell when I purchase gas locally and at times will mix this with the 93 OCT! the "girl" likes this go juice!

ask the Shell retailer where the gas comes from. Likely it comes out of the same terminal that all the other local brands come from. Local jobber (Huntsville, AL) here delivers to 7 different brands picking up at the terminal in Birmingham. Who knows what their gas really is?
