Non Stop Drive limit

[han94]

Its not a problem for mordern cars. I drove my 09 Corolla with 280k kms on the odo, from Karachi to Islamabad non stop, only stopped for fuel obviously, and back from Murree to Karachi, again with fuel stops only.

MashAllah all went well with Allah Karam, not even felt small glitch through out..... Alhamdulliah

IMO, old manual cars (like before 2005s) should be stopped for a rest, or shifted to neutral after 3-4 hours continous drive. Still, if its cooling and gear system working fine, maintenance done properly n frequently, then no worries at all.
Humans, on the other hand, must take a break no matter what car they drive, if not on another course like weed, coc, or ice, etc

While all the records set by pakwheelers might be reassuring for OP that vehicles can operate for long hours and distances; one must be careful that we don't encourage long nonstop journeys. Please take regular breaks and stay safe and keep others safe on roads too.

next time try wheat biscuits and strong espresso

what is your reasoning for this?

[horticulturalist]

Reasoning is given in the sentence next to it.

[Xulfiqar]

a manual gearbox is aircooled and is splash lubricated only. I can understand this concern for an overheated automatic transmission - where you leave the engine running and trans in Park to let it cool off. (even that was done on ancient ones with no locking torque converter)

[horticulturalist]

Ok sir, apologies

[mohsin-212]

What temp is considered higher than normal for ATF??? I noticed in my car that temperature increases not more than 95'c and then cools down when fan kicks in. But cant find any concise figure about maximum temp and how it is controlled

[Xulfiqar]

the ATF is cooled by the engine coolant, ideal temperature of ATF is between 75-90C - if your ATF goes above 110C, then its been severely beaten up and its life is cut in half.

This is also reason to keep cooling system in top notch condition. To cool an automatic transmission, you need to leave engine running, so oil circulates and cools down in the exchanger.

I will say Rent-a-car-drivers/ Ambulance drivers / and ppl with foreign passport (because of better road infrastructure and better cars they get use to non stop long travels) like to go non stop.

In Pakistan long routes have beautiful sights to stop and look around the countryside.

Again : a true driver can only go non-stop. On long route having a stop after 2 - 3 hours is doing justice to your body and machine.

hmm

not interested in seeing cows poo on the roadside or be entertained by a useless Hino tractor puller with several million "ashaar" on it.

several million "ashaar" --- is our tradition now. I love reading them all along with my wife helps bringing back romance days to my life

It means in an Automatic you should take a break to cool down ATF?

[Xulfiqar]

not necessarily - unless you have overheated it. (you can overheat it if you load your vitz with 7 people with luggage and climb to murree with it)

[mohsin-212]

I generally use Torque Pro app during long drive to monitor ATF temperature and have set an alarm if temp reaches 95 degree C. But I found that it never exceeds that temp range

[burhanahmed1]

A good condition car should not have any issues after 1-2 hours on highways. On mountain roads, particularly on descent, yes, cars should be given a rest for brakes to cool down.

There are many components which have to work well for a safe journey.
Car engine
Car brakes
Car tyres
Human element (fatigue, drowsiness)

All these things have their limits. The problem is we don't know exactly what that limit for each of these factors is until that limit is crossed, resulting in inconvenience, or, god forbid, an accident. Only safe way for us is to assess the conditions ourselves and drive within the margin that we are sure is safe.

The old school drivers never switch off cars or trucks while taking breaks. They keep the vehicle idling saying it is useful. Now I got the reason.
