I warm my IS-F for at least a decent 3-4 minutes.
But this articles is telling the readers a different story.

Gas prices isn't an issue and has nothing to do with anything for me.

But how necessary is warming up our IS-Fs and how long do you usually do it before driving.

I live in So. Cal. so the weather is just right, at least, most of the time.

i do mine for about 1min or two, however i don't puch hard until i see 2 or 3 bars..besides my work is about 2 miles from my house so i dont really get to see the third bar..

3-4 mins is a good number, get oil circulating an stuff. Think of it like stretching before you go running (in my case a dead sprint!) btw, I'm in Washington so it can be quite colder than Cali if you didn't know

I live in Canada... It's cold mind you my car is always parked in a heated garage my home is kept at 50deg and work garage is about 70deg. I get in and let it warm up until the high idle kicks down then I go. I usually keep it slow/low rpm the first couple blocks. I have always done that and never had any engine/trans related issues.

Warm up just until high idle is gone and you're good to go. Easy on throttle until you see 3 or so bars then you're good for WOT. End of story.

I usually wait until it idles after the hard startup and then i go slow until 3 or so bars

Same here. I usually wait till right after the idle (maybe 20-30 sec) and then go about my driving. I'll save the real roar for freeway onramps and highway driving after it hits that 3rd bar. I still see the older generation on my block start their new cars, take in the daily paper for a good three to five minutes, and then drive off and go about their business.

Fifteen, twenty years ago I used to warm my cars for a good 5 minutes. With today's cars I rarely go more than about a minute warmup. I do however try not to rev past 1500-2000 until I get some movement on the temperature gauge.

One of the big differences between the old cars and new is the quality of oil being used, especially if you are using synthetic. The old oils use to be like molasses first thing on cold winter morning. Synthetic remains relatively fluid even in the cold.

Today's technology does not require a warm up. However, the main thing that needs to happen before the engine sees any elevated rpm's is a uniform temperature. The top end of the engine will warm up before the crankcase does.that's not good. I don't like to punch it unless I see that the oil temp had warmed up a notch. That's really the main issue with today's engines as far as warming up is concerned.

I always try to let my engine warm up at least 2 minutes before I take off. Also I never drive above 3k before the oil temp is at 2 bars. I'm sure like most people have said you don't need to warm up modern engines for too long but it's worth the couple of minutes wait just for the peace of mind.

I actually warm the motor for about a minute in order to get the fluids circulating. I don't go more than 2000 RPM at least until the water temperature reaches mid gauge. Only beat the car after oil reaches two bars. This is all probably overkill.

When Ford designed their new 5 liter Coyote engine they tested it extensively. One of the tests was to idle the motor for about 1 minute then immediately take it to wide open throttle (about 7000 RPM) and leave it therefor more than an hour (they used an oil cooler). Next, they stopped the motor and cooled the motor to near 0 degrees F. Then they re-ran the test. They did this for the equivalent of 100,000 miles.

The motor was then torn apart. If there was un-due ware or any damage the test was a failure. The tests suggested very few issues and none significant. Although they changed oil at normal intervals no special oil was indicated.

That Coyote engine is very similar to the F engine except it does not use direct injection (yet).

I start and go. I just don't go past 3000 rpm until warmed up.

+1. Idling an engine is the kiss of death for long term reliability. It does horrible things to cam chains over time.

old habits and myths are hard to break. When i bought my first car , a toyota camry, in 1988, i was told by the lead tech not to warm up the car at all. That was almost 30 years ago.
