Pump gas is really impossible to check or police . And that's because pump gas can be one of hundreds of combinations . There are numerous manufacturers of gasoline with their own combination of additives, and many thousands of gas stations in North America . A very few branded stations purchase and sell only their brand of gasoline . Most are free to purchase any gasoline on the market , depending on which brand is cheaper at the terminal on a given day . So the gasoline you buy at the pump , in most cases could be any brand and probably won't be the same brand that it was last week . And the standards for pump gasoline are fairly relaxed compared to the standards for race gas . The ethanol content in pump gas can vary 2 or 3 percent from brand to brand , day to day . And there are pump gasolines that have no ethanol at all . And to add to the thousands of possible combinations of gasoline , there are 2 or 3 choices of octane at every pump , all of which have a different chemical make-up .
So setting benchmarks for testing pump gasoline would be impossible unless you allowed a pretty wide variance or the sanctioning body restricted pump gas to only one or two brands . And even that would be very difficult to police due to seasonal and regional variations .
