What to do for really freakin cold weather...

[HDMXDiesel0817]

Alright all,

I have a question well some questions; what do we do when it is several degrees below zero here? I was out talking to some drivers when I was at the Pilot this morning looking at more additive and the PS 911 and they are having probs too, even with the heaters and additive, it's still gelling. DOH!!!

How can we keep the fuel in liquid form while sitting over night. I for one have no desire to wake up every 3 hours to run the truck when it gets this cold. AND I know about the fuel additives but it will still gel. Let's see if we can come together and come up with a way to keep the fuel liquid from tank to engine and back to the tank (and all other places). There must be a way to keep it heated or warmed. I'm not saying at 70 but above the 20 or even the 0 mark on the thermometer. Say wrapping the fuel lines with an electrial heating element, something that will not pull a lot of current and won't drain batteries for extended periods of time.

For instance we have an engine block heater, this does not keep the fuel warm, but it keeps other vital fluids warm. Perhaps we can tap into this when we plug in our trucks at night (for those of us that don't park them in the garage, or don't have a garage) so not only will the engine block heater cord run the engine block heater but the heating elements around the fuel lines and tank.

How much current does the block heater draw by the way? Like if we added a third battery or something to run it for say 48 hours or so while at work (on the big road).

Well I've thrown it out there, I'm sure that we can figure something out here if some of you haven't already and I missed it somewheres. I would appreciate any input you may have.

Hi HDMXDiesel0817 from just north of you on lake Ontario. It has been cold here too. The Truck is good to start with NO starting aids down to 20 degrees below zero. All diesel sold north of say, Virginia, should be a winter blend, and therefore not prone to gelling. My truck sat out all night and it was -5 degrees this morning when I started it and it started just fine. I do not use the block heater, waste of money IMHO. I believe they are 1000W heaters, but that's at 120V house voltage. You can't run the block heater from your batteries.

Needbigtruck,

I have not used additives either, however I must rethink this or at least where I have been purchasing my fuel.

Two days ago it was -5 here as well and truck started up fine. Apparently the mobil truck stop does not blend their fuel, or at least well enough cause it gelled up on me last night about -11 or so at time of Gelling. Had a lil more than half yesterday afternoon and was like hey don't want water build up, so I pumped in about 13 gallons. Always fuel up there just through the woods and over the river. So last night...I get a little hiccup in my acceleration, cough cough...followed by uhoh.

All is good now. And truck runs just as good as new. Just won't wait as long as I did for that again...time to keep the additive from Nov - Mar. Poodoo

Move to California,....Problem solved

I'm using Sunoco Gold Diesel with no additives, actually Sunoco already adds it to the fuel.
Case in piont: truck was sitting 6 days not pluged in, this moring I could not start the 85 so I started the duramax to go to work -34C(-30F). It was a hard start but thats to be expected

Jon,

Sorry to hear about your gelling problem ... Since we live just around the corner from each other I know how cold it was last night (-11 at my house too). I highly recommend that you start using a good additive. I have always used one here in upsate NY ever since I first started driving diesels in 85 and I've never had fuel gel (knock on wood). Wrapping the fuel lines won't hurt but the place that plugs is the filter. When the fuel gets cold wax crystals begin to form and free water can freeze. A good additive will lower the "cloud point" (the temp at which wax forms) and prevent any water in the fuel from freezing.
(If you need some additive in a hurry stop by and/or give me a call and I'll lend you some.)

I don't have any gelling problems up here in frigid northern MN. My trucks sit outside at night too. jbplock is correct about the filter being the problem area. That said, use the FULL cold front provided with the truck, plug it in if it is going to be below zero. There is enough heat in there to keep the filter from gelling. Make sure that you change the filter every 10-15k miles too. I would also ask around the local fuelling stations for a place that sells arctic diesel. This is a little more money but is supposed to give #2 performance without gelling problems. I have been running it in all of my trucks during the winter for many years without a problem. That includes two semi tractors that have no starting aids like glow plugs.

Good Luck!

For those of you that live in very cold areas I always wondered about making a cover for the fuel cooler on the return line back at the tank. The fuel may then still be warm enough to heat the fuel in the tank enough to keep it from gelling. I'm sure it would still cool off on the way back up to the filter enough not to be too hot to not cool the electronics, but just warm enough to keep filters from plugging. Take a piece of large (6" or so) black foam pipe insulation, cut twice as tall as the cooler, and just as wide. Fold it over or around the cooler and hold it in place with a strap or two of velcro.

Just came back from the Cdn prairies. One morning at about -20F, wind chill was below -40. Filled up on summer fuel (after driving for a half-hour or so) and the truck died after 150 yards. Took 2.5 days to get the truck running again - in the end it took some anti-gel, a new fuel filter, and about 2 hours under the truck with Mom's blow hair drier (really!) to thaw out that fuel cooler.

I've been in cold weather with this truck for 3 seasons now. This is the first time it froze up to me, and I attribute it to summer fuel going into an almost empty, really cold tank, combined with about an inch thick of ice all around that cooler. Next season (drive home for Xmas) I'll DEFINITELY be putting something around the fuel cooler.

An old trucker once told me that if you have an engine that is gelled up or is too cold to start, you can put a pan of lit charcoal under it and heat it up. The radiant type heat without flames works well and fast!

[YZF1R]

Yep, that will work. A pile under the fuel tank. (Not under the fuel lines.) Another pile under the oil pan.

Note: This is for tractors. Not for plastic fuel tanks or oil pans coated with sound deadening material.

As has been previously mentioned, the base fuel is most likely the cause of the filter plugging problem encountered with the -40F temps. We have had a relatively warm winter to date here in the midwest and fuel vendors sometimes stretch summer grade a bit too far; reason: cost, greed, etc.... Blending/additizing for winter is expensive and many distributors wait until the last minute to go to winter blend/additization; sometimes too late.. Thus, if we purchase a summer grade fuel with a cloud point of +15/+20 degrees F, even with normal additization, it will begin to cloud at -15F to -20F.
And then we get the fuel distributor who hedges his bet and lightly treats/blends and the fuel clouds at 0 degrees F.. Even with normal additization, clouds at -30.. Thus when one encounters -40F, one needs to make certain the fuel used is indeed full winter blend and overtreat with winter fuel treatment . (no, it does not hurt to overtreat with additives such as Primrose 409; double dosing works just fine if one has to with no danger of over-treat)

I've been driving a Duramax for almost 4 years now
(2001 + 2003) and other than plugging it in at - 20F and putting on the top winter front I've had no problems. This includes many 400 mile trips at -40 at highway speeds. I know there are additives added at the refinery but that's it.

[HDMXDiesel0817]

It's amazing how much feedback one gets when they make a foopah. It's great!!!

Bill, yea I have been running the additive each and every fillup since that incident. The other thing I can say is that PS911 was sweet. Saved my butt big time. That's the first and last time I hope to see my rig on top of a flatbed...almost didn't fit.

stutzismydog,
That's 1 of 9 states that I have not been to (yet), but I don't think I want to move that far west.

Big Tow,
The arctic diesel that you mention, would that be why the Pilot (not flying J) is nearly 20 cents higher than all the other fueling stations around here? For example: Mobil 1.65 and Hess 1.59

Bellrule,
That's really interesting, I may try it just for grins and giggles

Thanks everyone for your input. Boy this is fun!

The student book for the LB7 says this about cold weather operation and diesel fuel use.

"Pour point depressants tend not to have much effect on the cloud point of a fuel, which is the first stage of waxing. This is a condition to which #2D fuels are more prone than #1D. Fuel heaters allow the use of fuels at temperatures substantially below their cloud point. The heater is an electric heating element that uses battery current to heat fuel in the sub system..... This electric element fuel heater is thermostatically managed so that fuel is only heated as much as required and not to a point, which compromises some of its lubricating properties."

The 6.5L fuel filter heating element is designed to activate at temperatures of +20 or lower (approximate cloud point of summer blend #2D). The training material for the LLY indicates that the fuel heater activates at +46 degrees F. or lower.

One other thing I have learned in a bind is that you can add some gas to Diesel in cold weather. I have never tried it and don't know how it would work on todays fuel systems. John Deere used to state in there operators manuals to add 1 gallon of gas per 20 gallons of diesel. I wouldn't try it just for fun but if I was in a bind...... Another thing is if you do get gelled up, you can put a new filter on that is full of straight power service and get things going again.

I've been using performance formula from Diesel Injection Service with straight #2(according to the guys working at conoco) and haven't had any problems yet.

What to do for really freakin cold weather...

Move to SoCal -- it was 56 deg F at 4:30AM this morning on the way to work. Got up to 78F.

Hope you guys get through the cold spell safely. [img]smile.gif[/img]

[george morrison]

Regarding the use of gas or 'dry gas' in diesel. No, not never, ever in our Duramax engines!!!
A high quality winter fuel additive *will* work to free up even a severely clogged/frozen fuel filter. The classic case of the engine starting fine, runnning for 10 to 15 minutes; then the fuel filter cloggs with wax crystals from an improper winter blend or insufficient fuel additization. In those cases, if the engine will idle (which it will in 99% of cases), a double or triple dose of Primrose 409 will work through the system in a relatively short time of idling, and the system returns to normal.. I cannot speak for other additives but there is no problem with over-treating with Primrose 409.
It is definately better than a fuel filter change-out, hair driers, etc. . Plus the problem will have been solved rather than the sometimes temporary fix and then filter re-clog down the road in the middle of nowhere...

I am newbie to the diesel crowd ( my 1st ) and I am still learning. I bought a 2002 GMC 2500HD Duramax/Al. with 24000mi on December 24 - Happy xmas to me!

We live in Maine and for the past 4 days it has not been above -10. Other than starting hard, I have had no trouble until 2 days ago. My wife's car would not start so she took the truck to work (~25mi). She came home at around 4PM and the truck ran with out a problem.

When she got home she shut down the truck for about 10min until we got back in and headed north, getting on the highway. We ran about 2 miles and paid a toll.

About 200 yards out of the toll, the truck started to buck and cough. We pulled over and the truck idled well, so we headed off again. The truck would not get above 40 for about 2 miles and then did the same thing, but stalled.

Trying to get to the next exit, we restarted and limped under 10mph for another 2 miles before the truck would not restart or idle. We waited 2 hours in the -20 degree weather before a wrecker could get to us.

Now here are my questions:
I believe that we had ok fuel, because the station that I buy at is where most of the commercial trucks fill up (I suppose that it could have been a bad load of fuel).

I beleive now that it most likly that the fuel waxed the fuel filter. Would you agree? During the service, they told me that one of my batteries was dead and they replaced that, I told them while it was in, they ought to replace the fuel filter - not knowing what the previous owner had done.

What would fix that - the fuel additives that you speek of here? What ones should I buy? Do they have a shelf life? Can you put too much in? Can you store them in a truck box in the cold that I am talking about without causing an issue?

Would a grill cover help? I did not get one in the truck when I bought it, and the dealer can not seem to be able to get one for me, even if I am willing to buy it - why is that? If I should have one, what would any of you suggest that I look for?

I know that it is a lot of questions, but I would love any help you could suggest. Thanks in advance!
