Fuel check question

[Mike Croley]

A couple of other items to keep in mind concerning race gas . One , the color does not and can not determine whether a race gas is legal . A perfectly legal fuel can be off slightly in color due to small variations in batch production . And the color blue or purple can describe many brands and octanes . I know of a blue race gasoline that's 100 unleaded . The color is merely a guide , if the fuel you're claiming to have is supposed to be red but the sample you're submitting is blue , there's a problem . Renegade 110 is purple , Renegade 112 is blue , Renegade 114 is turquoise , Renegade 116 is red , Renegade 120 is rose .
Race gasoline kept under ideal conditions has a shelf life of approx. 1 1/2 to 2 years . Once it's been opened , about half that long . Fuel that's stored incorrectly can go off in far less time . Race gas stored in metal drums or cans lasts the longest , race gas in tanks less so , and race gas in tanks that are open to the atmosphere much less so . Plastic jugs are actually the worst way to store race gas .
And lastly , there is race gas tech and then there is race gas tech . A local track may miss a fuel sample that should be thrown out . Fuel tech at a national event rarely if ever misses one .
