Not that it gets super cold in Texas, but simply because temperature is going down, the next week or so is supposed to be Texas cold; which is not to say it's actually cold. However all the Mexicans will be bundled up like Eskimos.
(if you're from Texas, that's less funny and more accurate).
Anyways, because of the colder weather coming, I've been reading into glow plugs. So if you don't know, the purpose of glow plugs is to heat up your cylinder before your ignition starts, to help efficiency of combustion on the initial early pumps before the engine gets up to temperature.
The general rule of thumb is the glow plug heats up to 500° in the first 2 seconds, and then up to 900° (on average) after about 15 seconds, and that's the point that you should be turning over the engine.
Now this being said, even in warm weather, it kind of makes sense to use your glow plugs at every start. However I will say that some of the articles that I was reading was saying that modern diesels regulate the glow plugs already, but if you're turning over the engine, what is it really regulating anyways. It's not like our Wranglers are sending power to the glow plugs every time we open the door and sit down.
I know we got quite a few guys on his forum with bigger diesel engines, and many of them bigger modern diesel engines.
So I ask, do you use glow plugs every time you start your engine?
As a bonus question, how long after you start your diesel engine do you typically let it idle and warm up before you start driving?
From what I've been reading, the minimum your engine should be idling before you drive is 1 to 2 minutes in 70+° weather, 3 to 5 minutes in 32° to 70° weather, and 5 to 7 minutes in any weather below 32°f.
