Re: Idling vs restarting an EcoDiesel

Brought my jeep to the dealership this week for an oil leak, and the next day I get call saying they added a dye to try and find the leak and let it idle for an hour . It's a slow leak so nothing showed up and I'm driving it around for a few days before bringing it back.

Anything that can be done to help reverse any damage they may have done by letting it idle for so long when the engine was cool to start?

Shouldn't be any damage. Some guys idle their ecodiesel for the whole time they sleep at rest stops (4+ hours) with no ill effect.

As I understand it, our engines have plenty of oil pressure at idle and the EGR system is off at idle. Those are really the only two things to worry about with idling and our engines do fine on both counts.

Re: Idling vs restarting an EcoDiesel

Definitely. Too bad the stock firmware doesn't have a high idle condition to prevent this... something the GDE tune offers an option.[/QUOTE]

But the GDE high idle only works under 36* ambient temps.

That's correct. The post you quoted was discussing idling in cold environments... and really, that's the condition one might *need* to idle rather than shutting down.

If you wish to explore obtaining high idle all the time, you might contact GDE to see what they say. They do respond to customer feedback.

The 10 second rule is just some advice gleaned from a hypermiler forum. It was for gassers, but I imagine this small displacement diesel to be similar.



Safety > comfort > economy. If it's unsafe or too hot/cold to be comfortable with the engine turned off, leave it running.


Where does that number come from, the 208 F?

Re: Idling vs restarting an EcoDiesel

Interesting discussion. The GCED on order is replacing a Dodge Cummins work truck with just short of 1 million miles. Over its life this truck has seen more than its share of idling. In the summer it gets started in the morning and never gets shut off all day to keet the a/c running. In the fall/winter its the same routine for cab heat. I am constantly in and out of the truck and its nice to climb into a warm/cool cab.

Never experienced any engine problems, just a bit more fuel consumed. Dont plan on changing my routine on the ED.

That's about where the temperature settles naturally when the engine is not under load. It's also the temperature where the thermostat just starts to open (fully opens at 225F).

Thanks for that, akinney. My oil temp is often less than 208 F when driving around town under normal city/highway conditions.

I did the same with the light military trucks I drove, and that's how I was trained (M151 Jeep, HummVee, deuce-and-a-half, 5-ton).

One million miles - impressive. I wonder if we can get a million miles out of these Italian engines?


<tangential diversion>
Over the years I have sometimes named my cars. For example:
- "Bubba", a 1970 Chevelle SS396, he was big and loud, and fast!
- "Gertrude", a 1970 Corolla station wagon, she was a rickety old lady, and slow

Thinking of the JGC CRD's Italian engine, I might name her Gina. Gina the Jeep. Gina, for Gina Lollobrigida, the Italian beauty from the 1950s & 60s.

Because she is white, beautiful, and I think I'd like to ride Gina for a million miles (in her prime).

Re: Idling vs restarting an EcoDiesel

I idle while fueling up, but that's it. Treat it like a gasser other than that. Also, it's illegal here in Texas to leave it running and parked somewhere (and no one left sitting in it). That alone is a bad idea.

Re: Idling vs restarting an EcoDiesel

I highly recommend anyone considering idling the Eco for lengthy times contact GDE and ask the risks of such practice both stock and with a GDE tune. I believe the change in injector timing with the GDE tune makes long idle times much safer for engine longevity.

Re: Idling vs restarting an EcoDiesel

One problem is that idling for an 'extended time' is not defined. Is that 30 minutes, or 3 hours, or 3 days?

My '08 Cummins 6.7 had an high idle setting. All you had to do was turn on the cruise control while in Park and hit set and it went up to around 1100 to 1200 RPM. I used it often...I think the dealer had to turn this on with the Scan tool if I remember right and...it worked at any temp...I wish my Ecodiesel had the same thing.
