I've always been told to warm my truck up before i drive it. They said something along the lines of if you don't the engine wont last as long. Is this true? I do it every morning for about 4 mins (sometimes more) it just seems like I'm wasting a bunch of gas. What are your guys thoughts? Do you do it?
If it's warm out, as long as it takes to put on my seatbelt and select a playlist from my IPOD, then I drive gently for the first minute or two. I dont sit there for more than about 30 seconds.
If it's cold out, might be 5 minutes or long enough to scrape snow or ice off and let the defrost clear the windshield if it's near freezing. 20 years ago more may have been necessary, but now I don't think so. I have watched people waste gas letting their car idle for up to 30-40 minutes in freezing temps. Pointless, and I think it's more cause they want it nice and toasty when they get in and pull away than they think it's good for the engine.
What we're worried about here is oil circulation in those first minutes after the car is turned on. I find letting it sit briefly then driving gently actually circulates oil and gets temps up faster than a 10 minute-plus idle. Most of whatever harm you're gonna do is actually already done right when you turn the key and fire it up anway. Better to take off gently and get the juices flowing than to let it idle and build up carbon deposits.

exactly...I let my truck warm up for few minutes if its cold or the truck has been sitting for a few days

Yea same here. If its warm, just until the oil pressure needle stabilizes. When its cold, just enough to melt the frost and get a little heat. No need to do any more IMO.

I do the same, I get dressed run out the door crank it up go back in ge the rest ofmy thing together then go i'd say at the most 5 minutes of idling. I'm fixing to have a remote start so i won't have to got outside to crank it.

I also go through a lot more gas. But I do like it toasty warm on those sub 0 days. I do it more for the comfort. But some for the engine.

Toyota's manual says to warm up for 10 seconds in warm weather. I go maybe 30 seconds, unless it's cold(for California) then i go about one minute. I use to wait until the idle speed adjusts but it does work better to drive slow for the first few minutes.
Eharri3 said it just right but since I live in Cali too, thought I would beat the dead horse.

M.A.D.ness AN INFECTION, NOT A PHASE
With my 4-stroke marine engine I use only enough power to plane until up to operating temp.
In reciprocating aircraft engines I want the oil & cylinder head temp in the green before making takeoff power.
For all my other gas engines, I keep the rpm down until they get warm. But that's just me.
In the summer I wait a minute or so, long enough to atleast let it idle down. In the winter I let it go a minute or so. If its really cold I will go outside and start and go back inside for maybe 5 mintes or so, I like it to be warm.
Waste of gas. If the engine doesn't have proper oil pressure in 10 seconds there's something seriously wrong and that's about how long it takes me to get situated to drive off. The only time I let it idle for more than a few seconds is if it's very cold (under 20°F in my book) and then I only do it for my comfort.
If oil companies were smart, they would give out remote starters to everyone. The fuel burn on a cold idling engine is astronomical if you really think about it. If everyone in the country idled their cars an extra 10 minutes a day....we'd use an extra 25 Million gallons of gas per day.
Oil pressure is one thing, oil temperature is all together different. I know, that's why we have multi grade oils.
Gas is $2.50/gal. What does my 4.7 Tundra motor cost? I paid $15,000 for my Yamaha F-150. Some airplane motors I fly are well over $100,000.
Again, I don't idol any longer than it take to back out the driveway. I just don't allow a lot of rpm's until the oil temp is coming up.
