I would imagine helium works as well, but I'd prefer to have an engine that used less gas.

Agreed.

Did anyone catch the Southpark with the 'Smug' being formed from people driving hybrids and loving the smell of their own farts?

Helium and Nitrogen are non-flammable and will work fine but it is unneccesary. They provide no change in mpg for you car. Just keep your tires inflated to the proper psi and things will be a-ok.
