Anybody had there truck gel up on them at dealership in town they had 4 truck towed in my included. A friend of mine gelled up to on his way had to be towed. Called several dealerships in general area of 40 miles said they had several duramax's gelled up also. Funny thing is all were 2005. Called gm and they said they don't know what problem is just add more additves then normal. HUH

Why would you call Gm if your fuel gelled up? Plus the dealer only keeps 3 gallons in the tank.

Pulled up to the pump tonight to fuel up as I was down to 1/2 tank. Pulled the bottle of Stanadyne Performance Formula out of the snow in the bed. To my surprise, the Stanadyne was gelled in it's bottle. Had been in the bed for about a week. Temp last night -2 F. ??????

from what I've heard stanadyne will gell in the bottle when cold, but when mixed with fuel is an anti gel adative.

Your fuel supply should have had winter blend in the bulk tanks by 11/15/05. Most here in northern In. had winter blend by 11/1/05. This is not a GM problem just operator error. It was -2 this morning and the fuel I bought on 11/2/05 ran okay. I run what comes off the tank wagon which is 2% soydiesel with additives the fuel supplier adds. Todays tank wagon price with 6% sales tax is $2.74. The fuel in town is $2.55 with 6% sales tax. I pay a few cents more for fuel that I trust is blended right and is of high quality.

Two dealerships had 10 2005 Duramax's gelled up at 40 miles apart in the Joliet,il area. that is why I called gm both dealerships said these are the first duramax's they ever seen gelled up so, either north central illinois got bad fuel or gm has a problem. Plus went to fuel comapny and they showed me the delivery receipt, receipt 5000 gals winterblend diesel delivered on dec 2. and I put half a bottle of fuel conditioner inalso.

How can GM have a problem? Fuel gelling up is not GMs fault.Someone could have made a mistake at the fuel company and they made fuel that wasnt blended even if the ticket says so.Maybe you should call Ford and Dodge dealerships and see if they have seen trucks come in for gelling.

Sometimes we take our fuel for granted. If you want to know, you must ask. What is the blend? There are lots of different blends, 80/20, 70/30, 60/40 and 50/50 with first number being #2 and second number being #1. There is also winterized fuel that is simply #2 with a fuel additive. The next thing is that different fuels from different refineries can have different cloud points and cold filter plug points. And fuels also vary from year to year. Now this makes me sound like I know what I am talking about and I do a little, but it is supposed to hit -21f here tonight and I have no idea what blend I just filled with the other day, because it isn't advertised on the pump and I am kind of lazy and used the credit card pay on the fuel island. So, if the cummins and the duramax both don't run in the morning, maybe I will just go back to bed):h Or, take a hair dryer to the fuel filter and get it good and warm;)

not sure on blend, but the bp where i fuel up at in nothern in. says fuel is good to -30f. with no additives, have never had trouble with mine

Mine has sat outside the last three nights while I was at work in northern IL and fired right up every morning. I'm using Stanadyne Perf. Formula and BP diesel. It was -3 degrees according to the mirror thermometer this AM.

Basically its seems to add up that apparently some gas stations fuel isn't what it may be, I just found it really odd that 10 people from different areas all gelled and all were 2005's according to the the service people at the one dealership and I talked personally to Five owners as we were at the same dealership all towed in, also to us five at the dealership not one us are first time owners and kinda know what the hell was going on. And all us got fuel at different places, just odd to me. That they all gelled up. so like I said perhaps area around joliet and south just not using #2 fuel even though they say they are. Service man did a test on all the fuel, he took a sample out of every truck and said the numbers are where they are suppose to be at on the fuel out of 5 trucks at my dealership.

Yessirr. I think I gelled up...mmmhhhh. When I got 4 miles from the house on the way to pick up my stranded wife(92 Ford Crown Vic-starter), truck lost power, rpm dropped, and kaput! I had a 100K btu torpedo heater blowing toward the engine area for 1 hr and only got it to run for 30 seconds before it would die again. Problem is, I haven't driven it much the last few months and suspect that I don't have any #1 mix in it. It will now!

I work at a dealership in the winter and we started 6 duramaxs yesterday to put anti gel in them and all of them started with number 2 in them i use houles anti gel and i always run number 2. the last week it has been -8 at night in north dakota

Hey All,

Hey All,

This is my first post, been reading for a few days now, enjoy the site. I just got my dmax a couple weeks ago, so far, love it. In my Ford I had before this truck I use to burn Diesel Clean, they have a winter and summer blend, but have not in this truck yet. Anyone use this?? I never had a problem with the ford, just preventive maintanence I guess. It was -10 this morning, truck fired right up, but I still want to run the diesel clean, boost the centine and seems to help increase my gas mileage. Any thoughts??

Thanks again

Mike

Yeah, if it is all in one isolated area I would have to say it is one of the fuel stations around there that is the culprit not the trucks themselves.

Keep in mind that many different fuel stations can get fuel from the same refinery! When adding fuel additive, be sure to keep it at room tempature or inside the truck and add it when filling up. The additive will gell and if cold when mixed, it won't do it's job. If you need to use a torpedo type heater to warm things up, don't forget to warm up the fuel tank, just don't get it so warm that it turns into a real hot fire ball:eek: :eek: -16F right now in Northern Wyoming and cummins started and ran and I am confident the dmax will also, plugged in all night.

Ok, this is retarded. How could gm cause the fuel to gel up. I'm not even going to argue that point, but look at it this way. 10 diesels in a 40 mile radius, hmm I'd say there was a bad batch of fuel delivered to that area. How many gas station tanks can one of those fuel truck fill? I would definately say that it's odd, but **** happens and someone probably pissed in the mixing tank at the refinery.

I had mine jell this last night here in iowa it got down around -18 i too wondered if the station had the right blend, it is usually not this cold her this early in the year.
threw the CEL, chugged , no power ......put diesel911 in it, ran a little better, took it in to the dealer this morning, had poo87 p010 P0401 PO404 P1093 P1223 P1244 CODES.
I HAD them put in the new filter i purchased last week, cost me 30$. the codes are unknown to me except for two -P0087 PO1093 =THOSE ARE FUEL PRESSURE RELATED. still cold here so to tonite we'll see what s s she does

How cold is too cold for #2? Down here, I dont think we get cold enough most of the time. Sounds like I need to carry a filter and some 911.

Yeah that emergency anti-gel stuff is a life saver.

BP Premier Diesel with Fuel Power FP60 and no problem at all.

-5F here last night and the truck sits outside

-18° last night. Still -11 right now.

My truck was fine because I filled it in town at the place that doesn't blend their
fuel. They use power service. I ran that all last winter and it was fine. I ran fuel from other places that blend as well but I like how the truck runs on the additive better.

My 8100 however was partly gelled. It started and idled, rough, but wouldn't rev up. I ran to town and got some power service and dumped some in and let it run a while so it would circulate a bit... After that it ran fine.. Although the hydraulics on the loader took a while to work.. Real slow at first...

Our red fuel has this hydrotex additive in it that my cousin sells... Evidently it isn't good enough for this cold. I'm gonna give him hell about my tractor...

Don't ever trust a fuel station????? Best insurance is add your own. No fun sitting on the side of the road, FREEZING your a## off.also plays havoc with your fuel system. best $10 bottle of insurance you'll ever buy.....

Had to go to town yesterday morning it was -35 degrees. Truck started fine but about 20 miles into the trip Truck started to gell. Turned the heater on the fuel filter (Gregs at lubespecialists) and she kept running but only just barely. Had some FPPF in the tank already but grabed the bottle to put some more in and when I dumped it into the tank it was gelled also about like yogurt. But anyway she kept running until I got down country with temps near zero then she ran OK.

I had an "incident" this morning! Driving out in the desert to work at "oh dark thirty" and temps started at minus 9 but quickly fell to minus 27 at the work site. About a mile from my parking area, my low fuel light came on on my aux tank and I shifted to my full OEM tank. It wasn't long before I began to lose power and miss. Immediately swapped back to the aux tank and she cleared up. Well, I can't make it back to town on the dregs of the aux, so I swapped back hoping to recirc some warm fuel and "mix her up" but wound up stalling and having to coast to the shoulder and crank a good bit back on the aux to get it going. Made it into the parking lot and poured 5 more ounces of FPPF into the balky tank. Will go out after lunch and try again to get it running and recirced. It threw a CEL, I hope I don't have a crappy tank of fuel! Will be able to get a ride to town and get back out with a 6 gallon jug, but I don't want to do filters in an open ice-covered parking lot!

Last winter I had a problem. Don't know it was gelled or water frozen in filter. Would not go above 30 mph and when you pushed to go it would just slow and blow smoke. took a good 15 mins before it warmed the fuel enough to degel or defreeze what was going on. Put amsoil diesel fuel modifier and cettane boost in and never had problem again.

When it starts getting colder than -10F for any length of time, there is but one solution, start putting in #1 fuel with additive until it warms up.

FPPF Total Power in all of my fuel. No problems whatsoever. I will be checking the last filter that I had issues with, but I blame that on dirt plugging at this point.

I have a 2002 that gelled up yesterday for the first time ever. only thing new is the replacement fuel filter GM changed out on a recall last month. supposed to be a 5 stage filter but I'm thinking the cold fuel isn't moving through it at low temps.

Just got back in from firing it up and trying to assure that I can make it back to civilization tonight. Ran real rough and made a TON of blue/gray smoke. Exhaust smells crappy, too. My code reader showed, 0093, 0004 and 4800 and finally cleared the Check Engine Light. Bad Fuel? I've GOT to run on it to get to town for more fuel in my aux.

I'm not going to suggest anyone do this but a pint of unleaded gas in 20 gallons of diesel will work in an emergency. I haven't tried this in the 2003 or newer pickups but it works in heavy equipment and semi's when the temperature takes a quick dip and you haven't cut your fuel yet.

Mine made a heck of a sucking sound when I pulled the filter. I left it run right up until I was ready to change the filter to keep the cab warm...

All diesel will gel up unless treated or you have tank warmers, just ask any truck driver who has ever been in real cold stuff. They'll tell you. We cannot blame GM for everything with our beloved beautiful Duramax trucks.
