Run Your Mercedes On Alcohol

[300EVIL]

While my independant MB tech was giving my baby an inspection last week I learned something very interesting. A guy walked into the shop and was talking to Harmon (my tech) about some emmissions problems he had been having with his Blazer. He couldn't pass emmissions, had no money and wanted a cheap fix. My tech told him to run the tank completely empty...... Then fill the tank with denatured alcohol???? In enstonishment, I said, "What!....... Sure you won't kill the engine!?" Harmon said he has done it on many cars with great success. They pass even with a cylander or two not firing.
Not like I would ever run my Mercedes or, for that matter any of my cars, on denatured alcohol. Does this actually work???
Wierd,
