letting your truck warm up

so today i went with a co worker to lunch as we get in his truck (it's been sitting there for about4/5 hours) he puts in drive and takes off. i suggest to him he should let the engine warm up at least a minute. he says that just waste gas. so my question is does it really matter letting your engine/oil warm up after your truck has been sitting for a few hours?

 

I start it, put on my seatbelt, adjust the radio and heater/AC and i'm on my way. If it is really cold I will take it easy for the first bit but I don't let her warm up all the way.

 

If it's cold, i'll let it run for a few minutes with the heater on too, letting both engine and inside get warm.

During summer, i let it run with A/C on full blast to get nice and cold. Houston heat sucks.

 

In the summer it gets about the time it takes to put on my seat belt. I don't hammer on it of course. Just idle down the driveway or out of the parking lot at work. Winter time 2-3 min.

 

I just go easy on it until the engine reaches operating temperature, regardless of weather/temps, same as I've done on any other vehicle I've owned...other trucks, high-performance engines, ATVs, riding lawnmowers, you name it.

 

Toyota themselves when I bought my truck told me just to warm it up for 10 seconds or so and take off that today's cars and trucks don't really need warming up like they used to.that's what I do never had an issue.

 

No need to wait. Obviously don't be hammering the gas until the engine is warmed up. Winter or summer. If it's super cold, maybe let it warm up for a 30 seconds to a minute.

 

"Warming up" just wastes fuel and time. Leftover from years and years ago maybe, I don't know but it's definitely one of those popular myths that lots believe because they hear it so often. I'll let it sit a few mins in winter but that's just to warm myself and get the defrost going a little before I get going.

 

The manual for our trucks states to let it run until it is running smoothly, then just accelerate slowly until up to operating temperature

 

I've always let my vehicles warm-up. With the tacoma I have an ultra guage and I never drive until it's at least 100* engine temp. Nothing behind it, it just usually takes at least a minute to get to that point so I figure that's enough time.

 

No need to let engine warm up. Carbureted vehicles struggled without a little warm up sometimes, but it never was about being better for the engine, just about stumbling when cold.

 

I use the Auto Start feature on my Viper as it runs for about 2-3 minutes so when I get in it's either cool or warm depending on season…..

 

I give it about 30 sec for the oil to circulate fully through the engine, then drive as normal. "Warming up" is a moot point because the oil would take 20-30 minutes to reach operating temperature anyway.
