Long story short, the company I work for took over a smaller one and some of the employees from the previous owners remained at the site. There was some hostility and tension from one of them particularly, her immaturity resulted in her termination. Fast forward a couple weeks and one of my coworkers had sugar poured in his gas tank last night and he was unable to drive home. His tank was less than half full, not sure of it's capacity but it's an older Cadillac so I'd imagine it's reasonably large. Would fill in it up to dilute the sugar help? Any additives that could go in the tank that would help dissolve the sugar?
