I'm dumbfounded!....Trying to save on gas.
Okay, I have an e90 streptronic 325i. I've read somewhere here that using the "manual" mode helps to use less gas. Here's my question, how do you change gears on this. First of all I don't know how to drive stick. So my question is not really how to change gears, but when to change them?
At what rmp/mph should one change from 2nd to 3rd...and so on?
