Anyone Use 5th When Doing 60kph?

[SS8_Gohan]

hey everyone,

just wondering if anyone puts it in 5th, when going 60kph??

i'm thinking from a fuel economy point of view, less rpm, less petrol used? It's probably around 1700, 1800 rpm?

Is it bad, or make no difference, to use 5th when going 60?

[Mr. Oizo]

i do, mine sits at around 1500rpm

but if i want to accelerate, i have to put it into 4th

[Al]

Yes less revs, but more load and load also uses fuel. Anything under 80km/h i am usually in 4th

[SS8_Gohan]

so if you're cruising on say flat road, 5th is better, but if you start accelerating, it's better to drop into 4th, even if you don't want rapid acceleration?

[ylwgtr2]

excessive load on the gearbox such as your describing is no good for the gearbox and will lead to excessive damage

[akeenan]

as stated in the other thread

I would never use 5th gear below 80km/h

[Russman]

Think of economy as how far your accelerator pedal is depressed, not how many revs it's doing. 4th with less pedal is probably better than 5th with more pedal. It does make the motor and driveline strain a bit.

cool, i don't really even do it now... but was just wondering.... i do go to 5th in my pulsar, but that's a pulsar that doesn't really like doing 90kph... (1.6l)

[sammus]

not to mention the big end bearing

do you get that really low pitched sound when you go in 5th at 60

[Mean_R34]

60kph?

1st gear. hehe

[adznight]

Probably a bit to slow, 4th would be better. About 80 for 5th.

[Sass]

depends on the car im driving and the road... and the car in front!!!

but i probably would be in 5th

[GTRgeoff]

Just to get the exhaust booming and set off alarms......

[SKY 34]

60km/h I'm already in my 5th...

[sloutch]

At 60km/h if you keep it at 4th gear, the 34 revs at about 21 or 2200 rpms, doubt that takes much petrol. As everyone said, 5th is only after 80km/h. It'll really strain the gearbox if you put it to 5th at such low speeds. More harm than good done.

[R31Nismoid]

im 5th, have to be

100km/h im @ like 3200

does it depend on the car or the gearbox or anything or is that just generally speaking it'll screw it?

[sloutch]

I guess if you are talking about the RB25DET engine, those are the gears used. Depending on the gear ratio of something i presume? But correct me if i'm wrong on that part.

If i'm not mistaken, in my mate's integra, he revs at 3,200rpms at 100km/h. So i guess it really depends on which car ur talking about.

[Sass]

what?! taking car sh|t?! thats over my head!!!

I dont know guys, I beg to differ. With the same throttle control, at different rpm's, the power fc did show a slightly different injector duty cycle. Higher rpm's meant more fuel.
