I got some odonnel's in early march and used bout half of itfrom there till probablylateapril early may. I got my car ready to run and i was lookin at the gas and it got a tint to it otherwise its somewhat darker than before which is wat happens when air gets to it . so i was wondering, is it ok to run it with the "tint" or has it sat to long and the fuel is gettin bad.
