What is
Icing?
Icing can
result from liquid water freezing in fuel tanks, fuel lines, and fuel filters.
Icing can
also result when water that is suspended or dissolved in the fuel falls out of
solution as the fuel temperature falls. This water first forms droplets and then
those droplets turn to ice crystals which will quickly plug fuel filters. Ultra
Low Sulfur Diesel holds twice as much dissolved water as Low or High Sulfur
Diesel. Biodiesel holds up to 10 times as much water (up to 1%) as Low Sulfur
Diesel.
The amount
of water that a fuel can suspend or hold dissolved changes as the temperature
drops. For example a fuel that holds .2% water at 60°F can only hold 1/2 that
amount at 30°F.
What to
Do!
When you
have ice in your fuel, there are only two choices. One warm the fuel up,
generally done by dragging the piece of equipment into a garage, or two by using
a product such as Thaw-It™ to dissolve the ice and disperse the water.
Thaw-It™
contains two co-solvents to break down the ice. Thaw-It™ will also remove
(disperse) liquid and dissolved water in the fuel and fuel system.
What
NOT to Do!
Using
gasoline, ethanol, isopropyl, or methanol is dangerous as it lowers the Flash
Point of the fuel and will likely damage pumps and or injectors.
How to
Use Thaw-It™
Remove
filter and replace if possible with a new one. If you must use the old filter
try to pour out as much of the ice or gelled fuel as possible. Fill the filter
with 50% Thaw-It™ and 50% diesel fuel. (Do not fill with 100%
Thaw-It™). Add 1 quart of Thaw-It™ per 50 gallons of fuel to the fuel
tank(s). Allow to sit for 20-30 minutes, then start engine. Allow engine to warm
before driving or operating.
Use Complete Fuel Treatment™ or Polar Flow™ to prevent fuel from
gelling in the future. If you have water in your fuel system use EnerFuel to
disperse water.
