Engine/Transmission (1998.5 - 2002) Has anyone come across bad, or old, fuel additive?

[RKail]

I filled up on Friday,(from a large and busy truck stop) dumped in 8oz of Power Service in the white bottle (1 gallon jug), drove 80 miles home. Truck ran fine, good power as usual. Let truck sit all weekend, not plugged in(wanted to hear 3 cyl idle, neighbors hate me now)Started Monday morning, temp was @ -9, and watched fuel pressure slowly drop to zero. I shut off truck and pulled the pre-filter out and opened it up to find a 1/4" layer of yellow goo. (Pre-filter and engine filter were cleaned and replaced about 1600 miles ago. ) Reassembled and restarted and same thing happened. Picked up some Diesel 911 in the RED bottle, followed instructions, truck is now running, and making 20 psi at idle. I feel I picked up a bad bottle of the additive, just not sure. This is the same truck stop that I buy all my diesel from all the time, just first time using additive from gallon jug and first time it has been really cold for us here. I did pour some of the Power Service out of the jug that was at same temp and it came out in large globs.

Sorry for the long post, just wanted to tell the whole story. Tried searching first, but no luck. I was just curious, threw that bottle away and will try something else or go back to the smaller bottles.

That’s pretty much what happened to me last week hears is a link https://www.turbodieselregister.com/forums/showthread.php?t=176585. I run Stanadyne fuel additive all year. I guess there not much one can do when they fill up with bad fuel. I don’t particularly care for power service but that just my opinion.

My brother is having the same problem right now... . he used a antigel [not sure what kind] & the truck threw a po253 code for vp44 low signal. He added some good cetane boost fuel injector cleaner to it & it is running good now.

It's not the additive, it's the new glorious ULSD fuel!



This board has seen MANY cold temperature related issues within the past month or so, and it's slowly becoming evident that the new ULSD clouds and gells far quicker than the LSD it replaced, and takes 2-4 times as much anti-gelling additives as the previous fuel. The "goo" you saw was not the additive, but the wax solidifying out of the fuel...

Thanks for the replys guys. But how is it that the additive left in the bottle in the cab of the truck was gelled? It came out of the bottle in globs. That is why I thought it was the additive that was bad. I was thinking that there might be a useable shelf life on these products for some reason.

Anyways, some Diesel 911 and some new filters and she's good to go.

Your issue almost sounds like another member's experience with the WI/MN state's bio/ULSD blend... the bio falls out of suspension...

Many of the fuel additives are actually polymers and have to be mixed with the fuel before anything will happen. Therefore both will gell alone but are not suppose to gell together. The problems is that after either are gelled it does absolutely no good to add them together. I had this same concern and talked to an engineer from the company of the stuff I was using, I was happy with their answers. The diesel 911 is different but I wonder what effect it has on lubricity?

PS Diesel 911 states it contains "slick diesel" for lubrication, but it also is the ONLY PS product that doesn't have the statement "does not contain alcohols"!!!!



I know I have a bottle of something or other that looks like honey and is supposed to prevent gelling to -40*F... hard to believe that when it gels on it's own...

RKail,



This has been hashed out in other threads, but the "NEW" Stanadyne has been reformulated for ULSD, has Power Service been reformulated?? Can't say one way or the other but it could be a secondary cause of quicker gelling. I know this year it was pure XXXX getting Stanadyne in stock as they would NOT sell their old stock and made us waaaaaaaaait for the new reformulated product. They are an injection pump hard parts company as well so I bet they know something that maybe the other companies out there didn't ??

Thanks again,

I was only using the Power Service because that is what our mechanic ordered for our fleet at work. Only he uses the quart bottles that is new stock, I bought on my own a gallon jug at the truck stop that I think was old stock. Lots of dust on the top of the bottle, should have known better. I do not know if it has been reformulated or not. My truck is the only one we had problems with. The rest of the trucks at our shop that we put additive in had no problems. One truck, a PSD, the driver refuses to put anything in, started up after sitting all weekend.

The filter on the engine has a fuel heater. Does your prefilter have a fuel heater also? If not... I would bypass it during the cold winter months.

The Power Service has been reformulated for the ULSD at least the bottles I have seen say it on the back. Unfortunatly, the ULSD is very hard to treat, and I dont care what brand of anti-gel you are using. When it gets cold, you WILL have problems. It contains more water, and it clouds and gels at a higher temp. than the good old LSD. All of the companys I talked to today regarding ULSD and their anti-gel products compatibility told me to at least double the amount of anti-gel doseage. If that doesnt work, then blend in #1 where available.

Thanks EPA...
