This is one of the few magic gas savers that sounds plausible.
I am no chemist but, as I understand it, platinum is a catalyst
and as such is not actually consumed in the burning of fuel.

True, but if you are 'injecting' the platinum into the air fuel mixture, it
is going out the tail pipe.

Platinum spark plugs seem to have worth and platinum catalytic
converters work for sure to reduce hydrocarbon emissions.

I think Platinum is used on spark plugs to increase lifetime, the catalytic
effect must be minuscule. On a converter, the platinum is fixed in place, is
not consumed, and can work continuously once it is up to temperature.

If this works maybe platinum coated rotors would help.

Very little surface area on the rotor, compared to a catalytic converter.
The mixture must come into contact with the platinum to have an effect.

Seems to me the mixture must be leaned to take advantage
of this. More fuel burned in the combustion chamber... more
air must be introduced.

However platinum is around $900 an ounce.

Bill, what do you think of cooling the exhaust gas to the
point where the water and hydrocarbons condense out to a liquid
and then separate the unburned  gasoline from the water
and recycle the gasoline to the fuel tank? The water can then be
fed back and used to help cool the exhaust gas upstream from the
condenser.

Seems like there is not much heat in the exhaust and a lot of
waste chemical energy when a car is going only 80 km/hr.
