oh no. i am dead serious. my point is that no one ever addresses such rolling or mixed ages of fuel when talking about when diesel fuel or any other fuel will go bad. and yet reality is that few storage tanks are ever taken down to zero gallons before being refilled again. i certainly don't have any answer here mind you. like so many politicians, i just like to raise issues and point fingers. real solutions and answers are someone else's responsibility.Seems like assuming complete mixing you have 62.5 gal of two year old diesel mixed with 62.5 gal of one year old and 125 gallons of fresh. Is this like a high school quiz? LOL
