Extreme cold weather

[mpauly]

I am getting ready to head up to the oil fields in North Dakota. The projected high is going to be -13 degrees and a low of -24 degrees. I am concerned about having problems with my diesel fuel system gelling or freezing. I use the recommended fuel winter treatment now in Iowa and plug my block heater in at night and haven't had a problem. The weather I'm heading to is much colder. Any advice or suggestions would be appreciated.

I don't think you will have any issues if you are already plugging in and adding winter fuel additive, maybe the next thing to think about would be your oil weight. Don't want to run anything too heavy in those kinds of temps.

Just keep doing what your already doing and maybe switch oil weight, I think you will be fine. These 6.7's have a good rep. for cold weather starting. One other thing you might want to do is add silicone to your door strips/moldings to avoid pulling them off when opening your doors.

I spent last winter in ND in the oil patch. I didn't plug in at night and the truck started just fine at -25°. I did switch to Synthetic Oil and did use an anti gel fuel additive and winterized fuel.

I did wish that I had a radiator cover. It was hard getting the cab warmed up some mornings. Even a 60 mile drive and the engine would still be in high idle trying to warm up.

if you get your fuel from a reliable source, ie, a big name company and not some little mid highway place, and you plug whenever you will be engine off for more than 3 hours, you will be fine. Its -30C here today and my truck will turnover no problem.

I'd just throw in a double dose of winter fuel conditioner until I was sure I was getting winter diesel. Up here it gets into -30's C and there have been lots of times I've never added any conditioner to my tank with no issues. Some companies like Shell have a second grade of diesel you can buy which has winter fuel conditioner already added, at least around here anyway.

The other morning I forgot to plug mine in and it was -21°f and mine fired right up to high idle. And said on the screen "Do not drive!" then had a timer that counted down from 20sec then said "OK to drive" I let it idle for about half hour before I drove it. I also am running power service anti gel cetane booster

Made a trip to canada last week the temp was -31F. I just added the recommended Diesel Kleen and never had a problem. The display did give a count down til i could drive, like 15 seconds.

How cold does it have to get before the high idle will kick in? Its been in the mid twenties and my idle has never picked up. All my previous diesels would idle up at 45F, but not this 2011. I was just thinking it was a new design with the new engine and not supposed to.

It's been 5-9°F around here in the mornings and mine goes into high idle at those temps. I don't recall it bumping up into high idle when the morning temps were in the 20's. I suspect the trigger point is between those temps.
