In my early days of driving I paid $17 for a 44 Gal drum (ie 200 Lt) at a time which was subtracted from the pump when I needed a fill up so long as I was in credit. GONE are those DAYS
Two weeks of $1.54 and 4 cents less with buyflies and now school has gone back its up to $1.97. However there are still operators selling at $1.65. Go figure.
