    What's the rev counter for?

    Why do I need to know how many revs my car does?

    Its been bugging me for 20 odd years.

    If its a manual car it is quite useful as it is a good indicator about which gear you should be in and when to change. Cars used for racing only have a rev counter and not a speedometer.
    If its an Auto its less useful

    The rev counter tells you how many times you reverse when trying to park.

    I thought it counted 1 every time you went past a church

    But I can tell what gear I need to be in because
    It's obvious, you can hear it in the engine, you know what speed you're doing, etc etc ... Seriously does anyone use a rev counter for gear change? by the way my car has a thing that lights up to say move up a gear... I know this cos I wondered what was happening .... When my husband was driving..!!! S why does my car need the rev counter, which I don't need and the gear change up signal which my husband does need!

    It is also used for counting how many revolutions you make on a roundabout before finding the correct exit.

    Audis have a far more useful feature. They automatically turn into pub or curry house car parks when you are trying desperately to drive home.

    D they call a txi for you as well?

    Anyway, back to the topic, what's a rev counter for? How have I got thru 20 odd years of driving, without ever referring to it?

    For the perfect gear change, right on the optimum of each gear.

    So, how many people actually need that or refer to it in every day life? I'm not being disrespectful, I'm just interested to know why motor manufacturers think we need it? Does anyone on here actually use it? Been clogging up my dashboard for two decades. I could have an extra mirror, or something.:)

    It's so that knob heads with their boom boxes on full blast know when to change gear - they can't hear the engine screaming its knackers off.

    Actually I use it occasionally when accelerating hard - not essential but a nice to have feature I would miss it if it wasnt there - why would you want a mirror in the middle of the dashboard?

    I use the rev counter often to decide when to change gear after reading an article about it. Most people don't change gear quickly enough and so waste petrol climbing up the gears. As a rule of thumb I believe it said you should change gear at about 2500 revs in a petrol car but only 2000 in a diesel car. If you do it by listening to an engine generally people change at a higher rev than that and over days, months, years that can make a really big difference to petrol costs. I'd say give it a go but you've got your light :)

    It's also handy for when your car stereo is on so loud you can't hear the engine :)
