I think I'll remove my iridiums and replace them with the cheapest platinums and see if this is true.
Platinums will work and the mileage difference will not be significant. 1-2mpg either way. But. Platinums get brittle (because of waste spark ignition) and break. In the engine. Where the party's at.
