The main point of this story is, as long as you argue correctly and intelligently, you can win almost any argument. Granted this one is a little more complicated than my example, but you all get the point.
I love this argument. That's why I always ask why my manual added HP to my engine? 15% loss of crank to rw HP as opposed to 25% less of crank to rw with auto.

The higher octane gas usually causes a build up in the engine of cars not designed to run them. The slow burning fuel doesn't get completely burnt, which causes carbon deposits to build up. Hence why plugs are usually changed to a colder plug.
