todays auto gas has s shelf life of rouhgly 6 weeks before it starts to
loose it,s octane value with ethnol,without ethonl that can be any
where from six months to two years. avgas will keep over 96% of it,s
octane over ten years and if you don,t belive me then go over to that
old plane that hasen,t moved in twenty years or more and long as the
fuel has not out (or stolen)it will smell as fresh as the day it
filled.and if somebody or anybody tells you that cant tell by the smell
then that person hes no nose or is an idiot
