What is the definition of "Bad gas"?

[Jerryl]

I searched the boards but could not find anything specific to my question.

I realize 93 octane is 93 octane, and nowadays it is hard to find 93 octane without the 5-10% ethanol. At times we talk about bad gas – What does that mean?

Gas with water in it or gas with less octane than it's sold for.

I'd second the Taco Bell bad gas syndrome. Have not eaten there in over 10 years.

If it is old AND not stored properly. Sometimes old gas gets that musty smell to it.

Why Taco Bell is still in business I do not know except it looks good on TV - WTH is the super finely ground meat they use

In my experience, bad gas can take two or three major forms (taco bell aside ).

First, the obvious improper or inaccurate octane labels. Many stories out there about 87 octane in 91 octane station tanks underground, due to human mistakes or dishonesty.

Second, fuel full of debris and condensation. All underground tanks have debris and condensation. My neighbor, a fuels expert for 50 years, has many rules he lives by when buying gas. For instance, if a fuel truck is at a station, he drives on by because refueling stirs up the junk in the underground tank, making it more likely you'd get bad gas. He times his refuling at his usual station to be after the fuel has settled a day or so.

Thirdly, Condensation in fuel here in the winter time will result in a frozen gas line....That is bad gas too.

Debris cloggs your filter and condensation is real bad when you are under boost. Most states check for these things, but some do not.
