To adjust the idle on a diesel engine semi, locate the idle adjustment screw on the fuel injection pump, which is typically near the throttle linkage. Start the engine and allow it to reach operating temperature. Gradually turn the idle adjustment screw clockwise to increase the idle speed or counterclockwise to decrease it, checking the RPM with a tachometer until the desired idle speed is achieved. Always refer to the manufacturer's specifications for the correct idle RPM range.
There are available many semi- and fully-synthetic oils which are formulated for diesel engines.
Depends...by "diesel tractor" do you mean "farm tractor" or "semi tractor"? You're SUPPOSED only to put off road diesel in a farm tractor. That's why they make it. If you have put it in a semi tractor, get hold of your dispatch/brief/lawyer right away for advice on what to do. If you have a pre-2007 engine your trouble is almost exclusively legal. If your engine is 2007 or 2010 compliant, you're probably going to screw up your EGR and diesel particulate filter, which will break your engine.
Between 2000 and 2500 for most semi-trucks.
My 2007 Volvo uses .5-.6 gph at idle (600 rpm), if I set it for a hi idle (900 rpm) it uses 1-1.1 gph.
The type of vehicles that have a diesel engine are pickup trucks, vans, semi trucks, box trucks, some smaller cars such as sedans and also some suvs have diesel engines in them. The GMC sierra has an duramax diesel in it.
If the engine is electronic, engine speed at low idle and high idle is controlled by a computer. If it's an older engine, a set of weights and springs work together inside the governor part of the injection pump to control low and high idle. In between these speeds, your foot does the job on the accelerator pedal.

Probably not. They would have to be clogged solid not to let engine idle in which case the engine would not run at any speed. If they were semi-clogged the engine would idle but hold engine back from revving up.
As far as I can tell, Iowa is not a no-idle state.
semi synthetic or can use full sytheyic
penrite recommend hpr diesel 5,which is a 5-40 semi synthetic
