When to shift during regular driving

[RyanGphoto]

While driving around.. What RPM do you normally shift to the next gear when accelerating? I normally shift RIGHT above the 3k rpm mark (unless I am wanting to hear the engine or trying to pass or something similar). So I was wondering.. where do you guys normally shift when just driving around on leisurely drives..

I notice when shifting from 4th into 5th I hold the 4th gear a bit longer than the other gears because I have to go up--over--up to get into 5th, so I stay in 4th a bit longer..

What are your thoughts?

It just depends on so many different factors. I will say shifting at only 3k rpm does feel a bit like short shifting the car.

Now, I live in a hilly part of Washington, so if I move from 2nd to 3rd, or 3rd to 4th at 3k rpm. I'm asking the car to 'manage' even puttering around at 2k rpm or less. The moment there's some form of incline, I'm going to be lugging the engine and asking for it to provide low end tq, that really just isn't there.

For most cars this will put it into some actually engine damaging conditions. Low-Speed Pre-Ignition. Which is more common on direct injection and turbo charged cars, but in high-load low RPM you are not doing your engine any favors.

There's never going to be a "right answer" to "when to shift" whether up or down. But there is a 'good feel' for the car and some mechanical sympathy. I don't know how to give you the 'tools' to right feel, you can drive other manual cars (hard to replace decades of doing so in a short period) you could ride along with others as they drive.

You will notice differences, and not all of those differences will be explainable by what's "better", and some of those differences may even be induced by someone else being in the car. How I drive for myself may be very different than how I do when I'm keeping passenger comfort in mind, or inversely if there's a slight desire to show off. Did I NEEED to shift down for that turn? Or was it fun to know my passenger was going to hear the revs kick up and feel more force in the turn?

It depends on what I'm doing. If it's just gradual acceleration I'll shift sooner. If I'm going for quick acceleration I'll shift later to get the most from each gear. But wringing it out to get to forty miles an hour seems boy-racerish. So, yeah, 3-3.5k is about where I shift generally.

I kinda do it by ear, when the engine starts to get loud to the point that I feel like it’s excessive relative to the speed I’m going, I’ll shift. I’m guessing it’s around 3.5-4k
