Don't forget deposit buildup on the exhaust valves, reduced effective 
diameter of the exhaust, catalytic converter damage, and 
carbonization in the combustion chamber(which leads to hot spots and 
raised compression, which leads to higher octane requirements or 
greater knocking danger).  Not to mention pollution.

I'd say that the "ignore burning oil" advice is rather poor.
