Sorry if this is a repeat topic. I did a search and didnt really find a clear cut answer. This is my first diesel and therefore my first winter with a diesel.

What temperature will diesel fuel gel? Also, i have read about winter blended fuel on here. Is this something that fueling stations should just have after a certain point in the year? What exactly is the difference between winter blended fuel and non-winter blended fuel? I have added no additives to my fuel and some of the nights here in OH have been getting pretty cold, i dunno if i should be worrying about gelling.

Also, where do you guys buy these additives, does wally world or like autozone have them?

Today it was good down to -30 with no additives added by me.

Holy piss is that cold.

from what I was told by a diesel injection mechanic, diesel will be non-pourable at 10 degrees. they do add additives at the pumps for the winter blend, in order to be able to pump it.

on another note, it is always to your best interest to place an additive, even if it is to keep the lubricity levels up for your injectors. you get an added bonus for separate the water better from the fuel. any moisture that gets in your tank can create microbial bacteria that can damage your fuel system. any moisture, from bad fuel, that gets to your injectors can cause your injectors to fail. Stanadyne is the one that is recommended by GM. They also recommend Racor. these are due to the process of how the separate things in the fuel, by emulsification. NO alcohol based additives should ever be added to your fuel system as you can cause damage.[I]

i hope this addresses any questions you have. you can find stanadyne locally from their website and any information on it:
www.stanadyne.com
otherwise, you can go on line, search for it at different internet dealers, and order what you want. I and others swear by the stanadyne and IMO, it is the best I have used so far and wouldn't use anything else.

from what I was told by a diesel injection mechanic, diesel will be non-pourable at 10 degrees. they do add additives at the pumps for the winter blend, in order to be able to pump it. Actually "raw" diesel has a pour point of around -40C before blending and additives. It's the "heavy ends" added in blending, that cause marketable diesel to jello. The additives do help tanks that are in storage, such as additional fuel tanks.

I add the Standyne performance additive to my 50 gallon in bed storage tank and have no problems this year. I range from a heated garage to -40 C days/nights without problems (knock on wood) I would expect some water vapour condensation to occur in the tank, but my checks at the fuel filter, have not found any water.

Had our 05 Dmax running on #2 diesel here the other day at -39c. That's -38.2F. If you factor in the wind chill that day (-52C or -61.6F). That's right -61.6F! Came up from Oklahoma to Saskatchewan, and hadn't added any conditioner to the fuel. Parked it for the night, and had no problems starting the next am.

68 today 77 tomorrow. Not 77 below. So far no fuel gelling issues this winter.

Yeah, yeah, go ahead and rub it in! I will get a short break from the cold though at the end of the month on a business trip to San Diego...

Nate,

Only us people feel the wind chill... the trucks only know the actually temp outside...

PeteThat is what I try to tell people too but some look at like iam nuts, vehicles dont fell wind chill just people,dogs,cats,the wife ):h ,etc. I just tell the people that dont believe me is then why if the temp is 10F degrees and the wind chill puts it down to -20F then why dont therometers read -20F, they just look at me in total confusion ):h ):h ):h and then they say yeah yeah yer right.

One way that the wind chill will affect your truck is how fast it cools down. The more wind the faster it will cool down.

True in some way, if its 10 degrees then its a 10 degree wind blowing through the radator not -15 or -20 wind chill blowing through.
