Anyone else getting bad fuel?

[Roots-type]

Twice in the last month I've gotten what I'm pretty sure is bad fuel. Pinging in 3rd and 4th at WOT. Switched gas stations (I only use big, frequently used stations to avoid getting old fuel). First tank at the new station was good but then I got another bad tank the very next time I went back.

I'm not all that knowledgeable on fuel and where it comes from vs. time of year etc. Has anyone else been experiencing this lately? 93 octane btw.

I got a random miss code, probably fuel related. I do not know what the answer is. I asked Van about adding VP C96 as insurance, but he said maybe add a little, do not go crazy with it. Probably too much of a hassle to jug the pump gas, pour off the water and then into the car. We do have non ethanol, but that is where I got the gas in question.
