I run mine till I'm done traveling for the day , weather it's a lunch break or fuel stop.. Thats why I have a high idle setting on it.

This has been a very interesting thread.

It appears there are two camps. One group thinks the manufacturer recommendations should be followed. The other group quotes subjective data from personal experience that contradicts the manufacturer.

Interesting to say the least.

Reminds me a bit about listening to the doctor. Doctor says you have to quit smoking and drinking or you will die. One guy quits and still dies. Did he live longer? Other guy does not quit and seems to live forever. Would he have lived longer if he had quit? ??????

We can idle or not to our hearts content. What will happen will happen and we will have to pay for it. Unless we dump it on a dealer.

That is the mouthful right there. I will operate by the manual until the end of my warranty at a minimum. Much easier to "dump" on the dealer when you can say that you followed the instructions.

really simple formula for me. when i look at a used diesel no matter what its in i pull the history off the ecm. no idle time no buy, period. i have a formula that tells me according to hrs. and miles what that should be. very easy.

Really interesting! How do you pull the history off the ECM? Would you please share your formula for those of us that would find this a great tool when purchasing used.

Why would you require your coach to have idle time in its history?

When a Cummins Tech hooks up to the ECM with his laptop with the Cummins "Insite" program, he can see just about everything the engine has done when running, and I mean everything!

exactly what he said. you can find out how much fuel its burned, what milage it has gotten, how much idle time, which roughly can determine has it been properly cooled down.
lots to learn by doing it.

i don't want to be buying turbo's, pistons, rolling a set of bearings in, or a premature engine in frame to the tune of about 20k. or more.

And while hooked up, personalize the ECM to your driving habits/needs. The ECM is set at factory defaults and works with the Transmission control module, and one can personalize how their engine brake works, and how it shifts..............Most just buy and drive.........and live with the factory settings...........Mostly due to lack of knowledge that changes can be made.

Some drivers dont let their coaches cool down but might idle at other times. Good luck with the math after reading the ecm trying to decide when the engine was idled. If the ecm shows many hours of idling I would take that as a negative.

Same here. I would consider the motor operating at below optimum operating temps, washing the cylinder walls down with fuel, excessive carbon build up and on and on.

Surely you guys realize that the entire run is recorded. Everything that you can monitor on the dash and more is recorded. Things like operating temp, vehicle speed, rpms, warm up time, cool down time, exhaust gas temp, among lots others.

It's all time stamped so they can profile your every use from key on to key off.
