Warming the motor

[the lane]

Do you warm your motor up every time before driving off ? and if so for how long ? I ask this as a matter of intrest as I was told, as long as you don't go over 2000 rpm the motor dosen't require pre warming.What do you think ?

Hi,
There is already a large thread on this, the FPV section i think ? a search should find it.

cheers

unless im late for work

I warm the car up for a few minutes. If I don't have time, I drive with about 5% throttle until it gets to operating temperature.

I warm up the GT but not the AU. The GT starts at 2000rpm basically so it needs warming. The AU I dont worry about.

I warm it up for a few minutes, mainly because I live 300m from the a 100kmh highway which I use every day. So its a bit of a necessity, I dont feel liking belting along the highway with a cold motor. I always try to take it easy for the first 5 min with any car im in to get the oil up to temp.

It is my belief though that good quality oil at a relatively light weight is probably more important for the motor however.

*In fact with my car, it get's quite insane when cold, it idles at 1900rpm and wont shift into 4th for the first 90sec or so.

I no longer warm up engines while standing. It's always done by driving off slowly (but not one of those "holding up traffic" iceholes) until the engine feels ok, temp gauge is where it should be and by then the diff/gearbox will be close to right temp.

If, as one post said, I lived near h/way then I would have to do a partial warmup before running at h/way speeds.

With my race motors, they had to be warmed up in the pits, especially the methanol ones. I personally believe methanol is very hard on cold engines even though I had no troubles with scoring cylinders or marking bearings.
It was done on jack stands with the trans operated in all forward gears and reverse and sometimes was idled through pits to staging lanes to help warmup.

The oil is only a tiny part of the problem.

The clearances for all the mechanical parts need to be right and they only come right when the motor/drivetrain is at temperature.

Idling engines for very long periods of time causes destructive cylinder glazing. There's no argument with that.

It's then stands to reason that idling for shorter periods will have the same effect but will take longer to do damage.

No group of people will ever agree on this whole issue. But whatever you do a common sense approach is needed.

I personally like the "immediate light load on cylinder walls" method the most.

As others have mentioned, it depends on the time and whether i am late or not. I do usually warn the car up for about 2 mins or so.
