EM-Z is supposed to improve gas mileage while reducing emission of automobile. However in reality the improvement on gas mileage was marginal if not zero. We were quite disturbed as EM-Z appeared to have worsened our test vehicle's emission. In our opinion if you would like to make your car smoother and more clean-burning, finding a good auto mechanic makes more sense.

EM-Z Field Test Report
EM-Z Third Party Report
EM-Z Automobile Conditioner is mainly designed to increase the fuel efficiency of internal combustion engines. EM-Z comes in two types: one is odorless clear light brown coloured liquid type, and another is white ceramic balls about 15 mm in diameter. When EM-Z in the liquid form and ceramic form are used together, between 10 to 30 percent of fuel saving is supposed to be obtained. It is said as high as 40 to 50 percent of fuel saving has been achieved for freeway driving.
A series of automobile
field tests was conducted on a 1989 Honda Civic Wagon
with a 1.5 litre engine and a manual transmission in the Greater Vancouver region between
June 21 and August 11, 1998 to evaluate EM-Z. There
appear to be a slight improvement (3 percent) in the gas mileage after three weeks of
the installation of EM-Z. However, in our opinion, it is not worth spending more
than 150 Canadian dollars on EM-Z , and going through all
the trouble to get a few percent of improvement.
The test vehicle's emission seemed to be worsened five times for hydrocarbons and 20 times for carbon monoxide at idle after application of EM-Z.
There is a corroborating report on EM-Z from a
third party. A businessman in Vancouver has been driving a 1992 Chevrolet Cavalier with a
2.2 litre engine and an automatic transmission for mostly commuting. According to his
record, EM-Z did not show any positive effect on the gas
mileage or the emission of his car.
Throughout the field tests we have been in contact with an employee of EMRO (EM Research Organization) in Okinawa, Japan that oversees the development and dissemination of new technologies on EM (Effective Microorganisms). We had provided him the test results as soon as they were available so that he could examine those. According to his advice we had made an extra application of EM-Z, and gone through the emission test. However, he has declined to be quoted in this section. He has also refused to provide us EMRO's official comments citing it lacks publishable internal test results or third party reports as EM-Z is still under development stage.
We would think the manufacturer of EM-Z, EM Sogo Net in Nagaoya, and EMRO have the responsibility to ascertain themselves the effectiveness of EM-Z with vigorous field tests before conducting a "beta" test in the consumer's market.
We would also believe, the consumers should be clearly informed of the nature of the "beta" test they are getting into that they are used as guinea pigs. For example, the nature of the beta test should be clearly advertised on Eco-Pure, the most informative Japanese periodical on EM. The EM-Z products also should be marked as "for field test only." They ought to remove the claim that "EM-Z saves gas from 10 to 30 percent, and cleans up the exhaust emission for 10 times" from the label of their product.
We also think if it is a "beta" test the price for EM-Z, 150 Canadian dollars for both EM-Z liquid and ceramics, is too high as there is no guarantee that it ever works. In short, the consumers were grossly short-changed by the irresponsible business practices.
Overall "Thumbs Down" shall be granted, not only to EM-Z, but also to the conducts of EM Sogo Net and EMRO.
