What temp does dino diesel jell at?
 

We're having a cold snap here in central FL and temps will be in the low 20s over the next few nights......I'm running a normal amount of diesel kleen right now, should I put in a stronger concentration of the winter stuff?

I can tell you at 8* we get jelling :-arrgh

in florida no....you will be fine with just the normal dosage.

Exactly where the formation of wax crystals begin will vary depending on both the quality of your region's raw diesel and what type/how much anti-gel your fuelling terminals are injecting before delivery to the stations.

Another factor is whether or not biodiesel is part of the fuel makeup.

Essentially, B100 is going to start clouding (beginning of wax crystal formation) around 32°-40°F. Your normal winterized diesel supply wil typically start clouding anywhere from 5°F-10°F, and that is without any aftermarket anti-gel being added by the consumer. Depending upon which anti-gel you use (and how much), you can reduce the cloud/gel points to as low as -45°F (from the data I've seen, anyway).

as lipless on johnboy and billy would say..."thats a lot better than the one i had"


Maybe some of you will get that?

19° apparently is the magic number in WA. At 15° I drove to work without an issue, then tried to go home to jump start my wife's car at 19° and I effin jelled up. Never had a problem one, even in colder weather.

Since I removed the mixing chamber I have found that 10* is where I start having problems even with blended fuel.

A full regulated return pretty much solved my gelling problems if I let the engine warm up for a while, just in case you were looking for an excuse to get the wife to let you buy one.

Not that I'm saying you guys don't control the purse strings or anything.....................:-innocent

Today had my coldest morning temp of 13° and i am running 50% vo. It did take several cranks to start the engine.

Better living through chemistry!

Oh crap i didnt realize the diesel gelled around 10 degrees or so cause right now its been 15-17 hopefully i wont see any problems. What anti gel stuff should i buy and how much/ when should i use it? guess i should start getting the supplies i need

diesel kleen white bottle has antigel in it. it has mixing recommendations on the bottle. 8 oz/25 gal. IIRC

For those of us in the South, don't worry too much about overnight temps that dip down into the 20's, even with untreated, unblended #2. It's not only about the temperature, but how long it's been at that temperature. Picture setting out a 30 gallon tank of water for a few hours when the temperature is 31 deg. Technically its below freezing, but you're not going to freeze that much water in a few hours.

Now if 20 deg is the high for the day, you really need to ask yourself why you're going anywhere. There's a reason we don't live up North. :)

Shawn tell them I said DUH HUH:-missingt they will know what you mean.Sorry I just had to do that.

Heck, 20* is shirtsleeve weather.

If it gets to 30*, folks are headed for the golf course in shorts.

:eek: 75 here tomorrow but low 50's when I get up so I'll have a jacket on when I leave in the morning and use the heater in the truck.
