I believed that Daox explained that his gas mileage dropped as his Wisconsin winter got colder and colder, and that he took measurements showing his weather stripping treatment allowed the temperature of the engine compartment to rise. If his engine had been running too cold to get normal fuel economy and the weather stripping allowed it to run at a more normal temperature, it makes sense that the weather stripping could improve Daox's mpgs.
