When to change gears?

Paki-share lang mga ideas nyo about shifting gears.
To start movement 1st gear syempre , and once the car is already in motion, 2nd gear agad, then cruising 3rd gear, tapos 4th-5th gear when trying to get some more speed.
My question is, at what speed km/h should you really change gears. Sabi nila when you reach 40 km/h dapat 4th gear ka na.
How about pag traffic?
Flooded streets/areas? 1st gear or 2nd gear.

Pls. post, post, post.

Actually, you should base your shifting on the tachometer (RPM) rather than the speedometer. Also depends on conditions and driving style. If you want to save on fuel, shift up when you reach 2000rpm.

If the engine sounds like it's about to blow up, it's either time to shift up into the next gear, or if you're in top gear... slow down. :hysterical:

-

The appropriate time to shift will depend on the engine and situation. For smaller gasoline engines, it's more appropriate to shift up at around 2500-3000 rpm (as long as the gears aren't incredibly long), while bigger gasoline engines and diesels will feel comfortable shifting up at 2000-2500 rpm.

On most cars you start in 1st gear... on some you can start in 2nd (L300, anyone? :hysterical ) with no problems.

There's no golden rule. In my old 1.3, I was in 4th by 50 km/h. In my 2.0, I'm in 5th. In the Focus diesel, I'm in 6th... :grin: ...as long as the car isn't lugging (naghihirap... or nagkakabayo...)... then you're in the right gear.

There is no hard and fast rules. Generally, listen to the sound of the engine and let it be your guide.

correct! tama si gerbo.

there are rules but its practically flexible, one can base it on the rpm

around 2k rpm ako mag shift depending kung kelangan ng extra power like pataas or mag overtake.

it depends... pero ang madalas kong napapansin, at 2000 rpm or even before it reaches 2000 rpm ang shifting

It depends on how do you want to drive..

race drive: shift each gear around 4000-6000 rpm. consumption is high, more engine strain.

Tipid mode: Change each gear below 2000rpm. Maybe higher than 2000 rpm considering you need more power to move at the right pace. results to better fuel consumption.

If your car is new, you can read the manual. most of them have description on proper gearing change.

Nice comment Niky..hehe!:grin: that is used in race style driving..:nod:

"If the engine sounds like it's about to blow up, it's either time to shift up into the next gear, or if you're in top gear... slow down. :hysterical:"

When you change at <1.5k rpm will it affect fuel consumption than changing at <3k rpm?

Also, when you coast on gear or when decelerating on gear would it affect fuel consumption rather than going neutral and just stepping the brakes?

Lastly, when the paper says max power 105hp * 6000rpm and max torque 102 ft lb * 4000rpm. What does it mean?

Thanks! :)

Depends if your ride can take it. Most gasoline vehicles will lug if you change up at 1.5k rpm, because that puts you at just 1k rpm in the next gear.

Cars don't use very much gas on coastdown. And if they're EFI, they hardly use any at all.

It means your car makes the most horsepower at 6000 rpm and the most torque at 4000 rpm. Which means that, typically, for best acceleration, you want to keep the engine revs between those two points in each gear.

Thanks sir niky!

Nag inuman kasi kami at pinag dedebatehan namin yung coasting on neutral vs coasting on gear kung ano ang mas malakas sa gas at mas matipid.

Ang argument ko mas malakas sa gas yung neutral kasi naka idle yung makina, kaysa sa coasting kasi hindi gumaganmit ng gas dahil sa engine cut of ng gas.

:)

Thanks po! :)

paano kapag mabilis ang takbo then medyo bumagal then speed up ulit. kailangan pa bang mag change ng gear?

depends on how slow and how fast you want to be, depends also on the engine.

if for example you are on 3rd gear * 4.5k rpm and slow down to 2.5k rpm you wouldn't change gear if you wanted to accelerate again. but if it dropped to 1.5k rpm and wanted to accelerate again, its better to shift to second and shift to 3rd * 4.5k rpm. something like that

You shift at torque peaks.

kaso bossing eh sira ang gauge ko, hindi ko pa kasi napaparepair kaya hindi ko rin matantya yung speed ko kapag tumatakbo.


dagdag din sana ako ng scenarios:

• 1. Let's say nasa 4th/5th gear ka, then biglang may tumawid pero hindi mo kailangan ng full stop. Ano ang tamang gawin? kailangan bang magshift gear after mo bumagal kahit tatakbo ka na ulit ng mabilis?
  2. Paano naman kapag, asa 4th/5th gear ka, mabilis ang takbo tapos suddenly kailangan mo na bumagal kasi traffic na pala(assuming hindi nakita sa malayo), kailan dapat magpalit ng gear? at sa anong gear, ok lang ba deretso 2nd or first gear?
  3. At regarding na din kapag decelerating ka na,let's say nasa 3rd gear ako then medyo traffic na, nalilito pa rin ako kung dapat na ba magshift gear pababa, kasi madalas eh parang kumakadyot* ang sasakyan ko kaya minsan hindi na lang ako muna nagshishift ng gear, kapag sobrang bagal na lang. (*sorry sa term, hindi ko alam ang tamang term eh)

Salamat...:help:

Magmatyag ka bro sa takbo ng engine mo. Usually what I do kung nasa fifth gear at me slowdown, I drop directly to 3rd. From 3rd to 5th uli if okay na uli ang trapik. Kung naka 3rd ka at slow down, you can drop to 1st directly. Maraming permutations yan. Basis talaga is dapat yung engine note mo ay hindi strained pakinggan.

ganito sa akin,
mabilis ang takbo at nasa 5th gear ako;
meron tumawid at kailangan kong bumagal; tapak lang sa brakes then hintay kung kailangan mag full stop or continiue di pa naman mamamatay ang makina, kung kailangan full stop tapak na rin sa clutch for full stop; kung clear na depende sa situation kung pwede pa rin ang speed ko sa 5th gear tapak na lang sa gas para bumilis uli, kung mabagal na change ka na sa aproprriate gear then proceed na ulit.

mas malakas ba sa gas ang engine break? or masama ito sa makina? kasi lagi ko ito nagagawa kung baga nasanay yung paa ko:grin:
