Article linked here.

but i love my remote start =)

i like getting into my toasty truck at 630am before i go to class. i idle for about 5 minutes while i get rdy.

Thanks for posting - good read.

Interesting.

Good read but it is ingrained in me to let my car warm up. It says it takes 30 seconds to circulate oil in the engine, but will the oil be warm? I live in the snow and can be at hwy speeds in less than 2 minutes. Regardless of what the article says, I don't think I can do that to my T4R!

Interesting read. Couple of disagreements, it says that idling the vehicle puts it in a rich running mode. For those of you not familiar with 1995 and earlier emissions testing, the vehicle must pass an idle test, that has the same restrictions as the high RPM test, it wouldn't make sense to put the vehicle in a rich running mode. Also near the bottom. "one recent study even links autism to air pollution" Reading that study it says that air pollution MAY have a factor in autism in SOME children. (I know a few families with autistic children, they live in small cities in areas with generally little traffic) but this makes it seem like there is a serious link between the two, there may be a factor in some cases though, not being a medical type person I can't completely disregard it. *end rant*

I do agree with most of written there though. Good post

Have fun getting into cold cars, you can damage the engine driving it cold, thats besides the fact that block heaters use electricity which is made by burning coal or other natural resources, the same as "plugging in" your nissan leaf-sh!t. Thats besides how you have to do with the stone cold car in the morning.

And if you dont warm the TDI up in the morning it is a horrible first 10 minutes before the heat START's to work.

It's a load of crap.

Its a habit that i dont wanna break. Driving in cold cars sucks a$$!!

Complete BS to me.

I sense Al Snore's minions or the like wrote this with the overtone of pollution and waste of gas/money crap.

I've changed my habits a bit. I don't warm up the car by sitting any more. I start and move right away, but I don't hit the gas. I let the idle pull the car down the street. Obviously I live in a neighborhood where I have to take a few turns and streets to get out to the main road. As I begin the merge onto the freeway the needle moves. That said, on cold mornings I wait about 30 seconds before taking off.

For newer cars not warming the up the cars is a good idea, but my 95 needs to be warmed up before I go onto the freeway. Otherwise it will not go into overdrive and I will be sitting at 3700 RPM for a while till it warms up.

Obviously not written by a mechanic. It takes your engine about 30 seconds to fully lubricate itself after a cold start, possibly longer in cold weather. Its best to avoid putting strain on an engine that is not properly oiled.

Longer then one minute and you are just wasting fuel.

BTW, spoken by a guy who has a vehicle with 205k miles and one with 280k miles, both with lots of life left in them.

You can't compare a cold start in Texas to an actual "cold start".

Touche. Longer in cold weather.

I have a hard time believing that after 30 seconds, your vehicle is ready go go highway speeds. I remember hearing from my auto tech teacher, a former mechanic, that the most damage can be done to the engine when it is cold. It seems like an engine is designed to run around 210 degrees, and going highway speeds before that means the oil isn't the correct temperature, which seems to have the potential to cause damage. I'd be interested in hearing from a mechanic for a definitive answer.
