Drivers who speed when their car haven run in
-
What are the consequences?I saw a few whom i assume that their car have not run in yet cos it's new from the car plate i saw. -
speeding is okay but u cannot rev ur engine beyond 3k RPM.
but wat's ur defination of speeding anway? if you light footed u can hit 100km/h in about 2200 RPM -
but i thought on the day when i bought my car,the SE told me that we cannot exceed 80km/h?regardless the rpm.Originally posted by casshern:speeding is okay but u cannot rev ur engine beyond 3k RPM.

read ur manual..some car goes by speed, some car goes by rpm...
-
manual zoon anot? my manual say anyhow ride, as long as dun push the engine too hard and also dun drive at the same gear same speed for extended time.
nvr talk about rpm and speed. i tot engine nature all is the same, so should use rpm best gauge. 80km/h is just that normal car, 6th gear at 3k rpm should give you about 80km/h. Please correct me if i m wrong. -

the best way to clock the first 1000km or ard that is to go KL and drive ard to shop and relax...then when u abt to go back u should have clocked 1000km already...

haha later happily drive ur brand new car there come back window kena smashed n rims kn stolen i laughOriginally posted by ceecookie:the best way to clock the first 1000km or ard that is to go KL and drive ard to shop and relax...then when u abt to go back u should have clocked 1000km already...

Didn't know new rio have 6 gear? These spec sounds like Mazda6. Usually normal cars, 5th gear 3krpm would be about 100km/h. -
hmm..Originally posted by wbucket:Wah!!! Didn't know new rio have 6 gear? These spec sounds like Mazda6. Usually normal cars, 5th gear 3krpm would be about 100km/h.
i got post thread b4.. about how many rpm @ 100km/h
my old camry 5spd auto.. 100km/h @ 2000rpm
my new mazda6 4spd auto 100km/h @ 2700-2800rpm
i think 5 speed cars.. 3krpm will be 140km/h already ba.. i think also depend on car's capacity -
my mistake. 5th gear max in my rio. u ppl rite, 5th gear at 2k is abt 80km/h. 3k rpm give abt 100km/h. what car gives 140km/h at 3k rpm??
-
my friend also looking for a new car. I just got mine without much knowledge, so got a rio(like the design and price). So after getting it, got some thoughts about it. The max torque say at 4700rpm. does this mean that the car is most efficient at 4700rpm(efficient as in least waste of energy)? So am i rite to say a car with low max torque(like jazz at 2700rpm) is more fc friendly than a car with higher max torque rpm? then what about power?

eh camry got 5 spd auto meh? be it old model or current model i thought it has always been a 4 spd autoOriginally posted by zerocool85:hmm..

Another cannot make it SE...Originally posted by scotts07:but i thought on the day when i bought my car,the SE told me that we cannot exceed 80km/h?regardless the rpm.
The rpm is more important in engine internal wear, not speed... speed will affect other parts like axles, tyres etc..
If he say 80 kmh max, disregard the rpm, then why not u drag 1st gear till 80 and just drive on first gear at redline lor.
Anyway saw one article on the web (dunno if true) that engine should be rammed early on (first 20 km) for piston ring to sit properly. This fella claim that if you baby the engine, the piston ring won't seal completely and you will have poorer performance/FC and more leaks.
Theoretically, it makes some sense, but not sure if its proven. -
tried and tested...we did it with our car when it was very new....on the way to KL we just maintain 100-120km/h...then we relax there and shop...then when it was time to go back...the car had already clocked abt 1000km/h...so we speeded back....heh heh..did 170km/h....total mileage was ard 1500km/h together.....the serviced the car....Originally posted by Lambo:haha later happily drive ur brand new car there come back window kena smashed n rims kn stolen i laugh u know those pple
park at safe place and carparks to prevent thief.... -
my old camry leh.. really...Originally posted by alberteinstein:my mistake. 5th gear max in my rio. u ppl rite, 5th gear at 2k is abt 80km/h. 3k rpm give abt 100km/h. what car gives 140km/h at 3k rpm??
3k rpm 140
4k rpm 160
5k rpm 180
5.5-6 215-220..
and my old model is 5 speed leh.. i got count the shifts... -
So jus how much would it affect FC(or anything else) if a car is run in the 'baby method'? or has anyone tried reving e car hard for e 1st few times?
-
Can rev, but must be slow and steady.

Shiok hor, the new mazda6 got 6 gears. I also like it.

camry 2.2? that's really weird.. if ur old camry does have 5 spds then how come the present camry only 4 spd? a case of technological degenerationOriginally posted by zerocool85:my old camry leh.. really...
3k rpm 140
4k rpm 160
5k rpm 180
5.5-6 215-220..
and my old model is 5 speed leh.. i got count the shifts... from what i observe, the situation might be when u hit the 4th gear, after a sec or two when the car has a constant rate of acceleration, the rpm will drop 500rpm or so thus moving into overdrive mode and that might lead you to think that the car has shifted to 5th gear. this is just pure observation when I drive.

think i've come across a similar theory awhile ago. can't say i really buy it.Originally posted by guitarman1:Anyway saw one article on the web (dunno if true) that engine should be rammed early on (first 20 km) for piston ring to sit properly. This fella claim that if you baby the engine, the piston ring won't seal completely and you will have poorer performance/FC and more leaks.

i particularly believe in wat i personally call "progressive conditioning". unless u are running in a race engine, the methodology to follow should fall within the "safe" side of conventional run in techniques. subjecting the car to various throttle loads, initially keeping rpms below 3k and gradually raising the bar as it proceeds to hit the next oil change. while not fool proof, this does enable the piston rings and bearings to get accustomed to various tolerances before being subjected to regular "abuse".
its not like u can drive like a wuss at one point b4 the prodigal 1k servicing and ram ur engine sky high the next and expect the rings and bearings to sit in instantaneously ya know

Just like to see what you might think if for the new car you are getting, the SE said you only need to first service it at the 10,000km instead of the usual 1000km, 5000km, 10,000km. Reason he gave is they use "good quality" engine oil as recommended by their Japan counterpart.Originally posted by tailslide:think i've come across a similar theory awhile ago. can't say i really buy it......
By the way, it is the Daihatsu Siron. -
my rxz also got 6 gearsOriginally posted by ditzy:Shiok hor, the new mazda6 got 6 gears. I also like it.

For normal 1.6 cars
4th gear @ 3k rpm is normally around 80km/h
5th gear @ 3k rpm is around 100km/h
For 2.0 and above
4th gear @ 3k is around 90 and above
5th gear @ 3k is around 110 and above
But this really depends on the horsepower and throttle level.
As for run-in during the first 1K before servicing.. try to maintain around 2.5k to 3 k rpm for all the gears not juzz only to smooth run the engine, its oso to save your life. Coz during the first servicing, they will oso help you to tighten some of the screws so its better to go slow first if u dun really wanna see your trye running faster than your car. A new engine is juzz like you juzz started to light your ciggie, need to inhale a bit first before u continure for a deep in hale to smoke.
After your first servicing, den its time to slowly build up the rpm, go to 3.5 den 4 den 4.5 and so on. It is oso to let your engine get accustom to the power lvl .Dun go for a full blow immediately after your first servicing if u wanna have a longer engine life. There are some idiots i kno who juzz ramp all the way and less den 1 yr problems comes out for eg. How come the FC like increase. Engine like dying for more power etc etc...
So far i have tried on my lancer and its all ok.. Highest reach is 180km/h on 5th gear @ 5.5k rpm and its working fine. Take your time to build up the cars stamina.. dun b too hasty about it. I waited till 10K service den go for the 180. after the first servicing, i only go to 120km/h.
Have fun running in the engine of your car

i'd say, these SEs can recommend and claim a thousand and one things, but at the end of the day, the car is ur's, and we all know dat some SEs are plain ill informed.Originally posted by wbucket:Just like to see what you might think if for the new car you are getting, the SE said you only need to first service it at the 10,000km instead of the usual 1000km, 5000km, 10,000km.

not dat i doubt their credibility. sure, japanese engines nowadays can lay claim dat they dun need 2 be run in. its juz a matter of how much the owner cares to try. ultimately, ask urself who is gonna be respnsible if ur piston rings start leaking or ur bearings getting burnt as a result of following their advice?
