Just about every morning I start my truck about 5 minutes before I get in it and drve off. I was just wondering if the is neccessery or is it just a waste of fuel?

You truck will actually utilize more fuel trying to keep at an idle but I'm pretty sure the amount of fuel used during this period isn't really anything you'll notice.
As far as it being a necessity? I've actually heard otherwise. With new technology, manufacturers actually recommend you warm up your vehicles by driving it very lightly. I'm not mechanic and most of this stuff I only see on motorcycles but I would imagine it has the same basic principles for full size vehicles.
Keep in mind this is just my uneducated guess.

It's a good idea. Yes. I do it for about a min. 60 seconds. Just to get the oil pressure up. Y'know? so all the lifters are getting lub. That's all you need. Some warm there car so they get the heater going. Not me, But- it's warm here year round.

I live in CO and it gets cold here sometimes. On those days I do let the car warm up for about 5 min., give or take. Yes, technology has come a long way, but the motor in my truck was built in the early '90's and has it's design dating even earlier than that (the old 350). While making sure that you have oil pressure is a good thing, too much pressure can also be a bad thing. When oil is cold, you will have higher pressure levels, enough to do damage? Probably not right away, but over time high pressure situations wear on seals and bearings more and more.

Well I think I will continue to at least give a minute or so to everything moving. Thanks!
