Diesel Fuel Gelling Prevention

Isnt #1 diesel very close to being kerosene? just wondering

 

Careful Krooser, you're showing your grey hair (not to mention suggesting the best product)!

 

I put one on last year after gelling in Saskatchewan at -28 with a bunch of Howes and some #1 in the fuel.

Just below 0 mine will start running rough and kinda louder about 2 minutes after turning that heated fuel line on it smooths right out. Mine is an Arctic Fox. I fully believe it will ungel filters.

BTW... carrying a couple extra pair of fuel filters and some fuel ungel like FPPF meltdown or PS 911 is another good idea.

 

Thought I would bump this useful topic and ask a question at the same time.

If I fuel in Percieval Iowa with some good northern blend fuel and proceed to Watertown South Dakota where the overnight low is 7 degrees, should I idle? The lowest temp I've run the Tri-pac overnight without idling was 20 degrees. That resulted in no problems at all. Just trying to get an idea where my trucks low temp threshold is. I've got a Cummins ISX motor and will treat the fuel with Power Service.

 

I've heard quite a few people mention that Diesel 911 is bad for the truck if used long term. Can anyone give solid information as why that is and what's in the product that causes the problem?

 

I was told that 911 may deice any moisture in your system and allow it to pumped through the injectors. That is what the shop said took out our injectors on one of our work trucks. Just what I was told.

 

With the bio diesel mix that most big chain ts sell I idl below 10 degrees they'd say the fuel is good for - 25 but I d trust that. The isx motor has a very high return rate so I haven't had any trouble idling or going down the road

 

Anyone use Marvel Mystery Oil as their additive? My brother's had good luck with it and buys it by the gallon at Walmart for about $18. Much cheaper than at the truck stops.

 

Gelling and waxing are two different things. Additives do *NOT* prevent gelling. Any claim to the otherwise is pure marketing. What additives do is lower the CFPP (cold filter plug point). Wax crystals start dropping out of the fuel as it clouds up, plugging up filters. If the fuel has "gelled" (essentially started turning solid) a regular additive will not work, you need to either warm the fuel or use diesel 911. Even diesel 911 won't work at that point.

The most common problem is actually water. Drain filters regularly to help with this.

Buy better quality fuel. Unfortunately this isn't always available.
