Idle time

During my PTI I'll start it after checking the oil. Give it 5 minutes at low idle, crank it up to 900 for another 15 and then hit the road. My temp at that time is usually 125 on water and 125 on the oil. I keep my foot out of it and RPM low until it heats up though. Once she's hot I run hr like normal. Before I had a truck that actually warmed up in a reasonable amount of time in the summer that was all it took to hit 160 on the coolant temp. My truck takes longer think the thermostat needs replaced not 100% sure but I can let it turn 900 all night in the summer and it'll never get above 150 on the water temp oil temp might hit 175 if I'm lucky. Other truck runs about 210 and 220 on the oil temp going down the road. Idling it'll warm up to 190ish and hover. Fan comes on every 30 seconds too.

 

Never turned mine off..but back in the day we didn't have apus

 

nor was it such a big deal to idle/use fuel. Now companies make it a huge deal. One example is Prime going 55 down a 70mph high way, I consider that a hazard.

 

10 minutes and then I'm on the road. 2007 freight, I never push it when it's cold.

 

i like to see at least 150 on the gauge before taking off then drive it easy up to normal operating temp.

start it after 60 seconds or so bump the idle up to 1000

 

I wont move the truck until it reaches 150 at least.

 

Rodding a cold diesel is never a smart thing to do. sometimes I just shake my head watching cowobys right after they fire their truck up take off...IN THE WINTER! I suppose when they lose a turbo because the oil was too cold to get to the turbine shaft they'll learn.

 

that or the guys that come right in off the highway and shut there truck off without idling it out fist. good way to take out turbo bearing always let your truck idle till egts are below 250 before shutting it off. or your burn the oil that's sitting in your turbo bearings causing a buildup over time. thus taking out your turbo

the biggest issue with not letting your truck warm up isnt so much the turbo as it is the pistions/rings and bearings your pistons will heat up much faster than your liners running the truck under load during warm up and engin bearings are designed for proper clearance at operating temperature. has less to do with your oil than you think, oil is properly circulating threw everything within the first second.
