The several experiments of Diesel vehicles using EFT were completed. The experiments were performed on chassis dynamometer and road driving test using test mode such as FTP-75 and LA-4. The experiments were employed to measure the effect eco-friendly EFT additives on exhaust emissions and fuel consumption efficiency. In this experiment, the following results are obtained by analyzing the data relativity between exhaust emissions and EFT additives. The value of exhaust emissions such as NOX, SOX, CO2 and PM were improved as Diesel mixed EFT additives at th ratio of 200:1. The improvement of resulting data value was best PM, NOX, SOX, CO₂and fuel consumption rate in the order named.

The two experiments of gasoline vehicle using eco-friendly treatment(Ecoburn) were completed. The experiments was done on traveling using the performance testing mode for chassis dynamometer and road driving test. The experiments were employed to measure exhaust emissions and fuel consumption. In this experiment, the correlation between CO₂and fuel consumption were found in gasoline vehicle. The following results are obtained by analyzing the data relativity between exhaust emissions and additives. 1) If the value of exhaust emissions such as CO, HC, NOX, CO₂were improved as gasoline mixed additives at th ratio of 300:1. The value of fuel consumption were worse compare to those of exhaust emission. The improvement of resulting data value was best CO, HC, NOX and fuel consumption in the order named. 2) The value of CO₂ were to be nearly proportional to the fuel consumption value.
