How long do you warm up your truck for?
I have an '06 3.0 that runs 5W20 through it. I usually just get in it and go unless I have to scrape the windshield.
Am I doing any long term damage? My wife warms her Fusion (same type of oil) for atleast 10 minutes because she likes it nice and toasty. I say that is just wasting gas.
What do you think?

If its crazy cold I let it (03 3.0 5w20) sit for a minute or two because I find if I don't the tranny will slip real bad for the first shift. Otherwise unless I'm scraping the windsheild I just get in a go.
If your drive is short and the engine rarely gets to temp (like mine) overtime sludge could build up, but proper maintence should take of that. Or so I've been led to believe.

I let my old '94 idle for about 90sec before I go. Kinda cool where I live. My owner [wife] lets her car warm up far longer, as your's does.
Once you learn to give up all hope, since you're doomed, you will feel a lot better about the waste of gas and money.

I wait less than a minute. Once the oil starts flowing, I'm good to go. I haven't noticed any ill effects, and I drive about 15 miles to work, so it gets plenty warm before I reach my destination.

I usually let it run until it comes off the "high" cold idle (a couple mins) at least. I also will then drive out of OD until I either get to a cruising speed over 45, or i the temp needle starts to come to life. As mentioned before it likes to slip shifts when cold. Where My work is, I actually put it in second til I get out to the main drag to prevent any shifting as the trans comes up to temp, just roll out the side streets around 2000 rpms.
And the amount of gas used to idle a car for 10 minutes once a day is so small, is it really worth it? Is there a NEED? no, not really. But it doesn't hurt, and seems to help judging by sound and feel.

It's alot easier to do these days with efi. Back when we had carbs if you didn't let them warm up they would buck and jump, sputter. Even ended up going to a hand choke on some rigs because the auto chokes sucked. With efi, you turn the key and go and the engine acts fine.

Yup, I fight it with my lincoln all the time, auto chokes were a bad idea! I let the Ranger run for about 30 seconds, that lets the oil circulate enough, and gets the exhaust manifold warm to the touch, so when it starts to elevate EGT under load it won't crack it. Then I keep the rpms below 2000, and keep it above 1/2 throttle until the heat gauge gets up to temp. No ill effects yet.

Unless it's below 32F, I just start and go. The engine warms as it goes. If it's below freezing then I'll give it a couple of minutes before I take off. It's not so much for the engine but for the other parts and fluids to come up to peak performance.

I'll give it at least 5 minutes before I go but even when I take off I don't mash the pedal thru the floor I take it easy on it for a couple of miles. I think the tranny has a harder time warming up than the motor.
