由於小弟每天要開130公里上下班
所以任何一點省油方式都會影響到我的荷包
我開的是350z, 之前沒上班都開市區的話 加滿油箱 16 Gallon 開260 英里吧
後來上班開高速公路的話,大概可以開到360英里吧,差不多每4天半要加一次油 (NT 1700上下)
我想問的是,請問高速時,開多快是高速裡面最省油的? 我平均開80 Mile/Hr
另外一個問題是,我開的是手排的,我換檔都是介於2000-3000RPM裡面換檔,請問這樣對嗎?
還有有時候我開到45 Mile/Hr時我會換到6檔,此時轉速會低於2000,請問這樣會省油還是耗油?
MPG will increase when speed increase. however, it will decrease after certain speed. u can find out by cruise control on certain speed. for example, 60 miles. record the MPG. next time, try 65 miles, then 70, 75, 80, 85.
then u will find that MPG is at the highest at certain speed. for example, 70 and 75. then u can do more detail test from 70 to 75 to find the best MPG.
in the future, when u want to save some fuel, u can use cruise control at that speed.
btw, my car has the best MPG around 72-73 miles/hr.
