Tuesday nights low was -16 in the mile high city. Fired the truck up with the new remote start with no problem (truck was plugged in). Headed off to work and about 4 miles into the drive going down southbound I-25 the truck lost pretty much all power. Fuel pressure was reading 0. Limped it to a safe place on the right shoulder an tried to trouble shoot. Fuel flowed out when I drained the bowl, but when cycling the pump, nothing. Okay it's either frozen somewhere or the pump took a dump. So I got a ride to the closest Irish parts store and picked up some diesel 911. Got back and poured it in the bowl and let it sit for a couple minutes. Tried to start and... nothing. By this time it's 8 o'clock and warmed up to -5. If it's froze south of the engine bay, it sure as heck isn't thawing out any time soon sitting there. So I call a tow truck, after a two hour wait had it towed to our shop. Driver dropped it in the bay.

So I head off to the job site planning on replacing the fuel pump over my long weekend. I use schaeffers neutra plus fuel additive so I'm finding it hard to believe that it froze. Well I got back to the shop seven hours later ready to run some tests on the fuel pump. Get in the truck cycle the key and bam... 65lbs on the guage. Well long story not so short, I'll be using a different additive in the future.

 

That sucks. really.
I have recently made the decision to go all schaeffer at the coming oil change.....now I apparently have some decisions to research.

 

Have a gander

Apparently they don't like Colorado, no local dealers.
I've looked into them:

warmed UP? Haha

 

Matthew, I gotta ask: What additive were you using?

Mark

 

schaeffers

 

Duh. Sorry, shoulda read more closely.

I am using the neutra plus. As I read the bottle now i see nothing about improving cold weather performance. Though I did see it on the website. I used stanadyne with the blue label last winter and had no problems.

Mark you know sub zero temps here are not unheard of, but definitely not the norm.

The truck likes the Schaeffer 7000. Maybe I'll try their winter stuff or go back to stanadyne. Although I don't like the thought of running kerosene through the injectors. Maybe I'm overthinking it.

 

It's funny how marketing convinces people that additives actually do something.

 

to be clear which product would be kerosene?

 

reading the schaeffer site, it seems the neutra + is a warm weather treatment that effectively lowers operating temps but doesn't safeguard against gelling/freeze. While the 2000 winter fuel additive is the one to run during winter months as it claims to:
any 1st hand confirmation?

 

Funny you say that. The guy I work for is now in his 7th superduty and has never put an additive in and never plugs his trucks in. He's never had any trouble from any of them.

I.O.M.H I read a post on here a while back discussing additives and remember something about the motorcraft and stanadyne using kerosene. I'm sure I can dig up the thread, but don't have time now. I'll look for it later.

 

I buddy of mine works at a facility for testing aircraft equipment. I'll see if I can get a few scenarios going to see if there is any truth to gelling inhibitors with standard ULS diesel and a few additives. Might be interesting see.

 

There are plenty of people here that have worked for Schaeffers that will chime in and give you some very good information regarding anti-gel. Water crystal formation and wax formation are two different issues.
