I was wondering if 116 octane would still be considered gas, instead of fuel
-
That's kind of an ambiguous question - well not entirely but you don't give much context. You posted in the El Mirage forum... are you specifically asking if 116 octane race gas would be considered "gas" at El Mirage? Or are you wondering about Bonneville? Or what? Detail man, we need more details. Is the "116 octane" you're asking about even a "gas" or is it something else? I can make lots of assumptions but won't. Instead you should probably gives us some better specifics about your question.

Pg 20 and 21 of 2014 rule book explains it all.

116 octane GAS (leaded or unleaded, oxygenated or not) is GAS.
Add even .0001% alcohol or methanol and it's FUEL.
EDIT: Make that 10% alcohol given pump gas sold @ that level.

Rule book allows up to 10% methanol but defines what is not. To much stuff without typing it all.

Yeah...I thought the same thing until reading the rules.
Formula 1 had a gas that passed their standards with 84% tolulene :-o
Like to have that tested by SCTA :-D Hey it might pass :-D

Sorry, didn't take the advent of E10 and E15 into consideration.

When I was working with Dan Warner in impounds at El Mirage I purchased a Gasoline tester. It came with information on each brand and grade. The info was available continously on the internet. I would ask the entrant for his gasoline info (brand and grade) then sample their gas and see if it matched. If it didn't you were gone. I cautioned every one about mixing brands or the grades in the same brand as they would show incorrect #'s and be illegal.
I have no idea what is currently being done.....I personally always ran VP fuels at ther were the most consistent.
PS: Never give an instrument tech an instrument because he will use it............JD

As JL222 replied, in the current rule book there is a detailed explanation of how gas is tested and what equipment is used.

I always wondered if aviation gas would pass especially the 115/145, the 145 is the octane equivalent with a rich mix. I know you can get 100 octane at airports but don't know about the
115.
It was tough to get race gas in Fresno area for awhile as the speed shop closed down during the recession, but they reopened. When I lived in Santa Ynes I bought 100 octane for El Mirage
at the airport, we ran but didn't set a record so gas was never tested.
In the book Thompson Trophy Racers ''like before Reno air races'' it says the 115/145 with water injection was the equivalent of 170 octane :-o
One of the reasons we water inject :-)

ALL gas class record setters are tested to the rule book specs at El Mirage. There are two options available - pass/don't pass.
