Not all premium pump fuel is created equal. “Yes, it is,” you say, “the octane rating is right there on the pump.” Well, there’s more to fuel–even premium-grade fuel–than just the octane rating.
First, the octane rating of premium can vary: East Coast consumers usually have access to 93-octane fuel, while those west of …
There is now a trend to label 91 as premium and 93 as Premium+ or some other BS name. WTF, no Premium is 93.

Some states don't have 93, so 91 is Premium, like here in Oklahoma.
Although a very small portion of gas stations have recently started selling E0 93, but it's crazy expensive. And performance gain over 91 is marginal at best.

Nope. Technically regular is 87, midgrade is 89-90, and premium is 91-94. Nationally the two most common premium octane ratings are simply 91 and 93, with the most prevalent differing regionally. Companies are also allowed to use other marketing names, but the grades will still fall into these octane ranges. This means they're also entitled to use naming conventions to differentiate between their multiple premium offerings.
The grades vary a bit with location as well. Around here, it's rare to see 91 available anywhere. Most stations carry 87 / 89 / 93 locally. Some will have 90 octane E0 as well, either instead of 93 or in addition.
Generally speaking, you'll find 91-octane premium on the West Coast and 93-octane premium on the East Coast.
