SW South Dakota | I have read and been told not to let a diesel idle below 1000 rpm for very long. It doesn't create enough heat to burn all the fuel and you get cylinder wash. When I start a diesel I will throttle it up about 30 seconds after it is running good. Our John deere 7730 automatically throttles up on start up if it is so cold then idles back down after warming up.
I typically don't let anything idle more than a half our unless it is cold out. A semi I will idle a few minutes to cool down then shut off unless I'm going to be loaded again shortly.
When I drove fuel truck, that thing was running most of the day and did a lot of idling. I would always idle it at about 900-1000 rpm. It was a 3116 Cat and had over 300,000 miles (unknown hours) on it before we had problems with it, and I think the turbo failure caused those problems. I would guess it probably had at least 10,000 hours on it. | |

how long do you let engines idle?
