I found this on-line for local gasoline. Will check other brand gas stations.
As of December 20, 2015, Peninsula Co-op petroleum sites will have the following ethanol contents:
•Regular Gasoline (87 octane) 10% ethanol, known as E10.
•Mid-Grade Gasoline (89 octane) 5% ethanol, known as E5.
•Premium Gasoline (91 octane) will not contain ethanol.
•Marked Mid-grade Gasoline (89 octane) and Diesel will not contain ethanol
Seems not all are the same for having the higher octane no ethanol, so I will have to look at them on site to get the latest info. They have changed over the years, even since 2015 apparently.
