Quick question, when your truck is cold do you let it idle for a little bit in the morning? We had another family function and my uncle bought a 2014 6.7, then questioned what the little light that looks like a womans breasts (wait to start light) was about... And in my family's fasion everyone told him how big of an idiot he was, blah blah blah and how he's going to blow the truck up. Anyway, we got in the debate of letting the truck warm up.
We have my grandpa who will literally wait a half hour until the truck is fully warm before he will go ('99 F-350 7.3), my uncle who starts the truck up and goes ('07 F-350 6.0), my other uncle who uses the remote start when he gets out of the shower and lets it warm up for 5ish mins ('14 F-250 6.7), and my cousin who says "start 'er up and rev the piss out of 'er" (13 years old, blew up a lawn mower and dirt bike).
My grandpa believes if you don't let it warm up, the oil is too thick (mainly on colder days) and you will damage your injectors. My uncle with the 6.0 says if you let it warm up like grandpa you will clog the turbo with coal. My uncle with the 6.7 believes the cab should be warm or cool depending on the weather whenever he enters the cab. My cousin is... dumb.
I don't know who is right (if anyone), I just don't see the turbo's getting clogged because ambulances idle all the time, big rigs will idle all night, and they don't seem to have a big issue. I sort of get the idea with the thicker oil idea if you're like my cousin who thinks you should drive it like you stole it, but if you're easy on it you're not making the injectors work too hard so it shouldn't be an issue, right?
I leave at 5 AM every morning, my truck is so loud it wakes people up and you can smell the exhaust in the house if I let it idle so I just jump in and go. The first half mile is a 25 mph private road, then for the next 10 miles it's 50 MPH with 1 slight up hill then a down hill and then I'm doing 70 on the freeway. I just take it easy on the first half mile, then getting up to 50 MPH I don't let it get above ~2250 RPM as there's usually no one on the roads at that hour.
Then the glow plugs was another debacle, gramps only uses them if the truck is below freezing, my uncle and I always wait for the light to go out (maybe a couple cycles when it's really cold), and my other uncle just found out what they're for so he hasn't used them.
