Engine warm up

[TrailMaster]

I usually do a few minutes. I wait for the tachometer to come down to normal idle range. Usually 3-4 minutes.

I almost always wait until the idle drops down to its normal range before taking off. In the summer months it takes a minute or two. In the winter it can take five to ten minutes.

It's a very noticeable sound when it changes from sounding like a sewing machine to, "let's go" mode.

HOW DARE YOU

My habit is one temperature bar when I don't use the remote start.

Wondering how long everyone warms up they’re 2 L eco-boost. I have a neighbor who has a GMC canyon and he warms his truck up for at least 5 to 10 minutes before he drives. Seems excessive.

According to everything I read you just want to get the oil into the turbo, and when parking you want to let the vehicle idle for a few to cool down. Never floor the vehicle cold.

Modern engines do not require to be warmed up. In the winter I give mine about a minute at 0 f (18 to -20 c), then we are gently off. I will drive it easy for the first few minutes while the internals (and tranny) are getting up to operating temp. The worst thing you can do in the winter is to repeatedly let an engine idle while cold then take it for a short drive (few minutes and shut it off) on a daily basis. The oil needs to get up to full operating temp to burn off the containments. The reverse is the same, do not drive an engine at a high throttle setting right before turning it off. (This last part would cook the turbo's bearings back in the day).

Most of the time usually 3-4 minutes, usually thru the app so I can get in and go. I want the engine to get the lubrication established and get a little bit of heat into it before I go, and I don't want to sit there waiting on that process.

That is the beauty of remote start. You hit the start button before you walk out the door so you don't have to sit and wait for the idle to get down to normal prior to moving off, what a great invention. I don't have mine yet so going to be different with remote start and no key to turn to run prior to trying to move the gear shift and killing the truck, F250 I forget so many times to turn the dang key to run...

Yea I know...I've been a rebel ever since my senior year (6th grade).

I think you should warm the engine a bit especially with the turbo motor...those hair driers like lubrication. I always warm up the big diesels for a few minutes before I take off especially in the cold weather.

After 5 million plus miles in big trucks I have yet to have a turbocharger fail.

But I don't let those engines idle, either.

Before I had a widowmaker heart attack a few years ago I would sleep in a cold truck using a 12v electric bunkwarmer that I slept on.... I was hard-core. Any temp above 10F the engine was off. Saved thousands of $$$ in fuel every year.

Later on I installed a bunk heater.

But now I can't do that...the old ticker lost 25% of its capacity after that and I'm just too cold to do that anymore.

Most of our trucks have a diesel fired hot air cab heater anyway.

Oh yea? Your mother wears combat boots!!!

Hahaha....

Well, I wanna thank everybody for their input. I didn’t know that there are so many, varying opinions and such great interest in the simple topic of warming up an engine. This is a great club and just a ton of fun. Hope everybody has a great Thanksgiving.

Man I try .... still working 50-70 hours per week. Still hate those 4am alarms!

if you have a device capable of monitoring obd2 values you will see the truck starts feeding in knock octane modifier at 3 bars of coolant temp. it takes a good while idling in cold weather to get there but when you start driving with low to moderate throttle input it warms up within 2 to 3 minutes.
