I never warm up my car in the morning and my car is park outside. Will this
effect the longevity of my engine?

Letting the car idle when cold is worse for the engine, better to drive it as it gets warm alot quicker.

It has always been recomended that you drive off straight away. only on the most extreme of tempretures (-5) do i let the car warm slightly this is only because its hard to see out of the front windscreen. The longer it takes the engine to warm the longer the fuel/air ratio is stronger the more carbon is left behind in the engine.

I usually start the car and go. I go slowly until I get to a major intersection, about 2 blocks away.

usually I just let the car (if parked outside for the night) warm up the interior of the car before I leave. Just so it's nice and toasty for my drive.

Nope, I wait about 30 to 45 seconds to get all fluids moving and then go. It takes longer for the car to warm up if it sits at idle besides it wastes a lot of gas. Keep it under 3K RPM until it reaches normal temp before applying full load to the engine.

there was a big thread about this in general bmw discussion about 2 months back. I still follow the manual on this issue, and don't let the car idle for more than a minute before taking off, keeping my rpms as low as possible.

I think its better to just start and go unless your in real cold temps.

The BMW manual recommends that you do not warm the car at idle...that you drive away and keep it below 3K rpms until it is warmed up.

With fuel injection warming up a car has become unecessary. Back in the day with carbs you had to warm them up so the choke would open up.

Ditto, this has been discussed on a few forums, and the optimum solution is what Tico posted. I live on a really long street that leads to an entrance to the highway, so I usually just creep at less than 2500rpm. By the time I hit the freeway, I'm cleared to go!
Member
No, because it's 95F+ here
Member
this is also new news to me. Is it bad if you let it warm up for just a few minutes so the interior is warm?
Member
i just wait until my revs drop to normal idling speed after a cold start, which is about 30 secs, and then drive off slowly for 10-20 mins

I'm too lazy to go out into the cold to start it to let it warm up. I start it and go.

I recall a thread where it was said to allow the car to idle for 30-60 seconds in order for the oil and coolant to circulate through the system. More than that is just wasting gas I believe. I don't see any reason why letting it idle for a few minutes would actually do any harm though.
What, me worry?
I open the garage door before I start the car... turn key, wait 5 seconds, and go (under 3k rpm until warmed up).
The car doesn't seem to mind at all, and I'm an impatient prick anyway.

yeah I just start and go, I had heard this before that you shouldn't warm up FI cars

yeh i am impatient too.

Start and go, the first road I hit after my drive is 60mph speed limit. Generally I get up to about 50-55, keep it under 3000rpm til the needles in the middle. Generally give it some stick after about 8-10 mins of driving at the earliest.

my engine is happy to start and drive away without warming up, but my transmission (automatic) is super sluggish until the car warms up. is it a transmission problem? once warm it drives just fine.
Member
I havent noticed any difference between warm and cold with my tranny like you describe.
Member
My 5sp tranny is a little bit stiff when itws cold, but once its warmed up and driven for quite awhile, it shifts extremely smooth. Its most likely normal to be a little sluggish, but if its really noticable maybe you should get it checked out.
Member
i warm up mine for 10-15 mins. its fucking cold here... -20 to -30 degress celcius. my engine doesnt sound tooo good when i start it up but after a few mins its okay.
