err.... Year 2024 coming....
just start n drive ..... once you exited ur housing area/multilevel carpark...
the car is ready for speed.

Some say need to warm up

Some say no need, but drive from lower gear

Just sit inside warm up for awhile, nothing to lose

Ya understand now usually fuel injection no need warm too long. But the warm up for auto transmission gearbox.. I also confused want to wait or not..

Usually I wait till the temperature blue light off and go. Time around 2.15 minutes but rpm still above 1k. If need want wait till below 1k need take around 6 to 8 minutes feel like wasted fuel.. but the warm up till 1k actually for auto transmission.. don’t know want follow or not.. because confused..

I drive Axia since 6 years ago.

I will wait until the blue light goes off, then I move.

I don't wait longer. But sometimes if I have extra time, I wait longer.

Ok noted understand thanks for ur reply

TS ur car engine and gearbox both have ideal/normal operating temperature .

The faster the you achieve it the better so start and drive slowly until the reach the ideal temperature then drive normally.

Idling take longer time to achieve the ideal temp and will increase wear and tear, not reduce it.

Better use high quality gearbox oil and change more frequently if you concern about the longevity of the gearbox and this goes for the filter too.

modern car, no need. Perhaps just allow up to 20seconds for fluids to flow.

just avoid hard acceleration when cold, normal traffic driving is fine.

my 1980's car also no need warm up till like what u mentioned

modern cars got very powderful oil pump as design. Just a second or 2 for the engine oil to move thru the oil alleys and start lubricating even the most hidden nooks even when engine has been left to cool down overnight.

Why on earth do you want to wait more than 2mins before moving. Even my 90s wira can see engine oil start flowing at tappet/valve cover area almost instantenously, and this is using 15W40. Yours with 5W20/5W30 is even faster.

Stop wasting fuel already, and more reason so when govt is going to stop rebate on petrol/diesel.

Even when blue light temperature gone off I also drive slowly till temperature reach 85c
Gearbox oil I charged almost every 15k mileage gearbox filler just replace when 90k mileage.

Usually I wait blue temperatures off then go. Recently saw video said wait rpm drop below 1k for gearbox better protection.. that y confuse. Because feel wasted fuel wait too long..

easy, start your car, while u put seatbelt and etc, u can drive already.

after that, watch your temp bar or icon, while it still showing cold, don't push it hard, drive normally < this will help to warm it up faster.

If you notice, when start your car, RPM will be around 1500.
If you engage say Reverse, the RPM will immediately drop to around 1000.
I think the car does this to protect the transmission already.
So don't really need to wait till RPM drop to below 1000 to engage gear.

Usually I wait till blue light gone I started to move slowly

Yes on around 1500 to 1400. Ya and also noticed that when put reverse drop around 1k.

Waste of time & petrol to wait up to 2 mins or more for oil to warm up. Modern engine just start & drive. I hv been doing for all cars and nothing spoilt other than wear and tear parts. If wait for warm up, how many years will you save yr car parts. Negligible. More important to change engine & gearbox oils regularly and stop worrying abt the rest. If it wants to break down, it will eventually and stop listening to grandmother story.

Fuel still cheap...so wait if you have time and contribute to global warming a bit...

Actually, no need to wait.

Think about it. When you start the car, the engine rpm is way above 1k. If you drive at this rpm, your speed is not really that slow. Even 30 years ago many article already mentioned that it is safe to drive immediately after you started the engine.

my house is about 120m to the main road. By the time I reversed the car and enter the the main road the engine cold indicator is already off and during this time, the rpm is below 2k. Many article said that keep the rpm below 2k while driving in cold engine which roughly translate into below 60km/h at low gear.

Old carb cars yes. Modern fuel injection not really. The thermostat is there for a reason.
