its clear that he does.

my bad, the post is in the 6.0 forum.

 

LMAO killa


I needed that

 

That's a well thought out, logical counter point there, killaford. I bet you were on the dabate team, weren't you?

It's great to find someone who can admit when I'm right.

 

Since some here seem to be drowning in their own....

...Let's get back on topic ...here it is once again:

 

Coming from a professional diesel tech. I would limit your idle time, it is tough on your fuel economy and carbons up parts. I would say in the summer, early fall and late spring. Let her run and warm up for five minutes, than start to drive real easy till the gauge gets up into the hash marks around the normal. In the winter, Let it run until you see the needle get to the first mark on the gauge, than same as stated earlier in my post. Plug the girl in when it gets below zero, much easier on the engine. If you get in start it and drive away, especially if it is real cold you run the risk of scoring a cylinder. As for cool down time. I you are towing or carrying a lot of weight, or been running for an extended time on the interstate let her idle for five minutes. This allows the oil to circulate through and cool down the turbo cartridge. The need for this is if you were to just shut it off the oil can boil out or cokes(a soft gooey carbon substance) up. In effect causing a dry start on you turbo bearings. This is what I have done for as long as I have been driving diesels. I have 264,000 miles on my 94 stroke and she is still running strong. That is also what I am doing with my 06' 6.0 and no egr problems yet.

 

I wait about a minute or two, and go, with above freezing temps. Always slowly and under 2K RPM for the first few miles. Isn't that better than idleing for 10 or 15 minutes? I'm not sure when you talk about limiting idle time how 15 minutes can be good, even when plugged in below freezing. Can't argue with F250Wheels. That's quite a commute and I'm in the same area.

 

if you do the high idle mod, then you can let it idle for longer periods of time though, with no build ups.
i know a lot of people with diesels. and most let them idle for a while. i know i let my 97 idle more in the winter, like for short stops somewhere, than just shutting it off.
that engine has 125k miles and still runs like a champ. always plugged in below 35 degrees.
i'll do the same with my new truck

 

Where I live has pretty much everything to do with how much of a warm-up my PSD gets. I idle it for a minute or less, drive two miles at 35 MPH (posted speed limit), then 4 miles at 55 MPH (posted speed limit) then hit the interstate at 70 to bat-out-of-hell (not the posted speed limit). Of course we don't have too many below freezing days in my neck of the woods. If I had frost on the windshield, I'm sure I'd idle it longer.

A question I've had for awhile is; why can a diesel generator run (at idle) for hours with no adverse effects? I know there's a big difference between a generator and a 6.0 and it's probably a dumb question but I've never really understood it.

 

A diesel generator doesn't have an EGR valve does it? I believe most of the problems related to idling is because it causes the EGR valve to get "coked".

 

Good point. Another reason to deep-6 the EGR valve I reckon. Mine's still connected as I haven't had an issue with it. I run Diesel Kleen every fillup though, maybe that's helping.

 

untill temp gauge moves a littile bit upward

 

it's funny how you never hear of anyone saying DON't idle too long with a diesel, until this 6.0 comes out and it's now a bad thing.
my 7.3 had idled for a long time, maybe an hour or more somestimes in the cold. i have never had any issues with it from doing this.
big rigs idle for hours and hours with no issues.

why is the 6.0 so picky about how long it idles. when i think of a diesel, i think it's meant to be idled when you need it, because i was always taught it's bad to start and stop a diesel for short trips in and out to places. so why not let them idle?
i've never let my new one idle much at all, maybe 10 minutes tops, not sure that's really a long idle. maybe for 4 hours that's considered long and maybe there would be issues with wet stacking but for 10-20 minutes, to me, that's normal.

 

LOL

maybe it's just mine, but after 10 mins of idling, my truck (with the STOCK tune) will NOT go up my 12% grade driveway at more than 1-2 mph..... with the tune, once you can get it over 15mph, it shoot some smoke, sputters, then spins the tires.

tired of this pos.... once they get some miles on em, it's always something. getting very bitter!

and apparently, glow plugs ARE NOT covered in the psd 100k warranty ???? (im on my 3rd bad one)....



that 5500 rebate on f150's is lookin good.

 

IMO, it is because of the generally poor quality of diesel fuels. At least until ULSD becomes prevalent. Soot build up is the single worst cancer that can infect a 6.0.

I have read on informed sites that the 6.0 was designed for optimum performance utilizing diesel fuel with a minimum 46 centane rating. The National average, as I recall, is less than 42 cetane. This is why many folks highly recommend the use of quality diesel fuel additives at every fuel up.

The 9 nine county N. Texas area has been somewhat fortunate that, a while back, the EPA mandated that local distributors offer fuels with a minimum cetane rating of 48. It is my belief this is the reason our trucks here seem to have fewer fuel / EGR Valve related issues...though some have.

I have a # of friends in the trades and they idle their trucks a good part of the day...with no 6.0 issues...each of them have followed my lead and depend heavily on fuel additives to keep them soot free.

 

More importantly for where you live Rotella 10w-30 from November till April. Ever see 15w-40 when the temps start to drop below freezing? It's like gel. Check the owners manual for your conditions.
