After the application of EM-Z the gas mileage appeared to have improved for about five percent. However, we cannot attribute the improvement recorded in this case to the positive effect of EM-Z. As for the effect on the emission of the vehicle, we do not believe EM-Z has shown any improvement.
Introduction Conclusion of the Report Application of the EM-Z Inventor/Manufacturer's Comments Add Your Comments and ExperiencesA businessman in Vancouver has been driving a 1992 Chevrolet Cavalier with a 2.2 litre engine and an automatic transmission for mostly commuting from his home in suburbs to his office in downtown Vancouver. About one month before he applied EM-Z to his automobile, he had started taking notes on the odometer reading as well as the quantity of gas consumed whenever he refueled. After the application of the EM-Z he has kept the gas mileage of his car for about three months.
At the beginning the car had run 86,000 km mostly driving in city. According to EPA (Environmental Protection Agency), 1992 Chevrolet Cavalier 2.2 litre with an automatic transmission has estimated gas mileage of 9.9 km/litre (23 miles/gallon) for city driving and 13.2 km/litre (32 miles/gallon) for highway driving. Before the application of EM-Z this vehicle has an average gas mileage of 8.5 km/litre (21 miles/gallon) for city driving that is about 14 percent short of EPA's estimated gas mileage. Considering the automobile's age and slightly poor gas mileage, EM-Z should have a best chance to show its effectiveness.
After the application of EM-Z the gas mileage appeared to have improved for about five percent. However, we cannot attribute the improvement recorded in this case to the positive effect of EM-Z. As for the effect on the emission of the vehicle, we do not believe EM-Z has shown any improvement.
The following tables are the gas mileage log and emission tests results kept for Chevrolet Cavalier.

After the application of EM-Z the gas mileage appeared to have improved for about five percent. However, in winter when the gas mileage before applying EM-Z was recorded the city traffic tend to be much slower as the day light is short and weather is rainy. Therefore, gas mileage in driving around Vancouver tends to improve as the season shifts from winter to spring. Accordingly we cannot attribute the improvement recorded in this case to the positive effect of EM-Z.

The emission levels has been showing fluctuation most likely caused by the varying conditions of the vehicle. Before taking the British Columbia's AirCare emission test on April 28, 1998 the vehicle took a "tune up" maintenance as its engine tend to stall at that time. Considering this and the pattern of the past test results, the lower emission recorded on April 28, that was about two months after the application of EM-Z, was probably caused by the effect of the tune up maintenance. In other words we do not believe EM-Z has any positive effect in reducing the emission of the vehicle.
The table bellow shows the application of the EM-Z.
| Products | Applied to | Recommended Dosages | Actual Dosages |
| EM-Z Liquid | Radiator Reservoir | 200-300 ml | 200 ml |
| Engine Oil | 50-100 ml | 100 ml | |
| EM-Z Ceramics | Radiator Reservoir | 5 pieces | 5 pieces |
| Gas Tank | 15 pieces | 15 pieces |
Prof. Higa recommends heavier dosages for an older cars that are 10 years old and/or more than 100,000 km on their odometer. However he also states that as EM-Z is anti-oxidant, too high a dosage may actually decrease the fuel efficiency. (Source: Issue 22, Feb. 1, 1998 Eco Pure)
