I just bought a Honda Civic DX and don't have the owners manual. I have been driving stick for 11 years now, but my boyfriend is arguing with me about when to shift. I would like to know the info that is usually in the owners manual about when to shift. Thanks!Thanks for all the info so far...here is the kicker--it does not have a tachometer! Having a speed would be the best info....I have driven hondas quite frequently, and know that they are hi-rev engines to begin with....so....he is saying that it should be shifted into 3rd gear going 25MPH, and that just seems to be too soon.
