5. Standard method for car fuel saving test: (the effect is more significant for cars over six years old) 5. ：【车龄六年以上效果最显著】

A). On the departing route, fill up the fuel tank (when fuel is visible) at the nearest fuel station to highway.
B). Put the mileage meter to zero.
C). Keep the speed at 100 Km/hr, but do not set the speed.
D). The distance is about 100 Km.
E). Upon arrival, get off the highway, fill up the fuel tank (when fuel is visible) at the nearest fuel station to highway.
F). Record the mileage, the fuel meters being filled, and put the mileage meter back to zero.
G). On returning, put the “BT-X Fuel Saver” into the fuel tank and wait for 20 minutes before departing.
H). Keep the speed at 100 Km/hr, but do not set the speed.
I). Upon arrival, get off the highway; fill up the fuel tank (when fuel is visible) at the nearest fuel station to highway.
J). Record the mileage and the fuel meters being filled.

The data for highway round trip may calculate the fuel saving rate for the first time you use the “BT-X Fuel Saver”. The best fuel saving effect shall be after the car has been driving for more than 100 Km after the “BT-X Fuel Saver” is place in the fuel tank (or when the air exhausting pipe presenting the steam) when the test shall be done again at the same road section to have much significant effect (since the original carbon accumulation in the car take a while to be cleaned).


A. 去程于距离高速公路最近之加油站加满油（以看得到油为准）
B. 里程表归零
C. 时速100公里，但不可使用定速
D. 路程约100公里
E. 到点后，下高速公路到最近之加油站加满油（以看得到油为准）
F. 纪录里程、加油公升数、将里程表归零
G. 返程将BT-X环保节油器置入油箱内待20分钟后始出发
H. 时速100公里，但不可使用定速
I. 到点后，下高速公路到原来之加油站加满油（以看得到油为准）
J. 纪录里程、加油公升数
以往返所得数据即可算出初次使用节油器之节油率，最佳节油效果应是在车子加入节油器行使1,000公里以后【或是看到排气管出现水气时】，于此时应在同路段再行测试一次，效果最为显著【因为车子原有积碳须一段时间才能清除】。
