at what tempature does #2 gel up?

 

Is this what you are asking about?

From the Amsoil site:
https://www.amsoil.com/storefront/dfc.aspx


"As the temperature drops, the wax naturally found in diesel fuel begins to form crystals. The point at which wax crystals form is known as the cloud point. These wax crystals eventually clog the fuel filter and starve the engine of fuel, preventing it from starting. While low quality fuels may form wax crystals in temperatures as warm as 40°F (4°C), most fuels have a cloud point near 32°F (0°C). The point at which the wax crystals clog the fuel filter is known as the cold filter-plugging point (CFPP). AMSOIL Diesel Concentrate Plus Cold Flow Improver lowers the CFPP by as much as 34°F (19°C) in ULSD."

 

so im guessing the #2 around here is mixed? its been around 4 to 10F around here for the last week or two and my truck starts fine. im just wondering at what point should i start using additives or switch to #1

 

I use additive year-round. It helps with lubrication of the fuel system. On my 12 valve I run fuel conditioner and/or two stroke oil in the summer time. In the winter I use a fuel conditioner with anti-gel. Either Diesel Kleen in the white bottle or the NAPA brand.

But to answer your question, Ive experienced fuel gelling in temps as warm as +20deg F.

well then i guess im gonna have to start using anti-gel then its been getting down to -10 here and they say its colder in north dakota which i will be at for the next two months

 

94ram,

If your buying your fuel at the Flying J truck stop there in Rapid City then its most likely already mixed 70/30 but is still a good idea to add you own anti gel just to be safe. Also its a good idea to carry at least one Qt bottle of Power Service 911 (or some other brand of your choice) under the seat just in case you ever do gel up.

 

ive been fueling up at safeway since i get member discount
ill be heading up to wahpeton, nd in a couple of weeks so im sure i will definitely use anti-gel there

 

Fill up in ND, it will be blended for the temps already

 

ok will do

what exactly makes #1 different than #2?

 

Amsoil is full of poop. They are trying to scare you into buying thier additives.

The highest cloud points you will find for a diesel #2 is +15°F. Most northern climates will have lower cloud point. Additives can only lower the operability of a fuel by about 15-20°F below the cloud point. (The CFPP, measured on a lab instrument, may be 34°F lower, but don't count on that to translate to the real world)

 

Diesel #1 is a little ligher cut of distillate fuel than diesel #2. It will have a cloud point about -40°F. Every 10% diesel #1 blended into diesel #2 will drop the #2's cloud point by about 4-5°F.


K-1 Kerosene and Diesel #1 are essentially the same thing.

 

I just looked at Chevron's diesel info and see that the listed CLOUD POINT
°F MAX for Spokane WA from Oct 21 to Feb 29 is +26 and it has a POUR POINT
°F MAX. of -20.
