I heard I should not wait for the enging (e.g. in a cold morining) before running in road, and that this can make sirious damage to the enging. Is this true?

no this is only true if you start it up and then rev it up to like 6k evreytime till it warms up. start it up drive under 3k and the engine will be fine unless its a diesel then i suggest at least a 5 min warming up

The "latest thing" I've heard is it's OK to drive off as soon as it gets oil pressure, and that happens within a few seconds.
I'm not sure "warming it up" for a period of time really hurts things that much, unless it is warmed up at a low RPM rather than a medium RPM.
Warming up at a low idle might keep things like cylinder walls and valve stems which are "splash lubricated" from getting lubrication as fast as if you were driving.
So with long initial warmups it's more of a "why do it if you don't need to" sort of thing rather than a "you'll trash your motor if you do it" thing.
The best thing is to drive away after a few seconds (as soon as the engine idles smoothly) and drive gently at medium speeds until the motor warms up. If you don't have a temp. gage you can tell it's warm when your heater works!

You can run your car while it's still cold but you risk doing [serious] damage to it. its better to let it warm up then to pay to have it fixed. It's like microwaving something thats been frozen.
Also in the winter, try minimizing the amount of short trips you take. When your car sits for a while in the cold parts start to develop ice on them and when you start up the engine, it melts this ice, forming water. If your car runs for a while the water evaporates and is fine. But if you drive for a little bit and turn it off again the water remains in the system and causes havoc.

ok. all of us is extremely accurate in the experience that they stated you may let your automobile warmth up contained in the nice and comfortable temperature climate. All vehicles run on fluids. gasoline, tranny fluids,ability steerage fluid,anti-freeze, etc. Now even as none of those fluids will freeze till at like -35 or so temps, they do get thick and sludge like even as chilly. once you first initiate your automobile they fluids are all contained in the pan and in case you positioned the vehicle in rigidity and hit the gasoline the fluid should not be the position it needs it really is why you listen vehicles "whining" even as they shy away contained in the morning because the flexibility steerage fluid has no longer lubricated the pump adequate and for this reason has to artwork harder. The tranny fluid is all down contained in the pan and by no ability lubricating the transmission and lower back once you positioned the vehicle in equipment it really is putting the tranny below pressure without lubrication and that is causing unneccessary friction on the tranny aspects.i'll go on continually. the striking answer is to commence it up and wait till you listen the engine extremely down and be conscious the RPM's drop it really is an staggering handbook to apply to understand in case your automobile is warmed up adequate. keep in options the fewer warm the temp and the longer it has sat there no longer all started the longer you may let it warmth up.,

You can start your vechile and go, just take it easy for 5mins till the engine warms up to operating temperture. unless you have an automatic transmission, you should warm it up for a couple of minutes or else you will have transmission problems further down the track. its more imprtant to warm up trans fluid than the engine. Keep your regular oil changes in the engine up to date and you should'nt have any problems with cold starts wear and tearing those vital rings and bearings.

First of all, use SPELL CHECK...it's your BEST friend.....It's engine, not enging..lol...Just kidding.
It REALLY is best to run the engine for a few mins to get the oil that's way down in the oil pan BACK up into the engine and to get ALL of the fluids pumping, so to speak.
You don't ALWAYS have to...it just makes sense to do so, especially in cold weather.

depends on the year of car, oil type, oil pressure, and outside temperature. If it's that cold--you should use a block heater. older cars without oxygen sensors it would cause excess gas to enter the crankcase and wash down the cylinders of the engine causing excessive wear.

A car typically needs 30-60 seconds to warm up. However if your car HAs over 75000 miles on it you should give it about 3 minutes....

When the oil pressure gauge starts moving, throw it in gear and go. Works for all my U.S. cars, maybe the foreign cars need pampering?
