LSD (Low Sulfur Diesel) and ULSD (Ultra
Low Sulfur Diesel): Beginning June 1, 2006,
80% of available diesel fuel in the United
States will have less sulfur. Beginning October
15, 2006, additional labeling on diesel fuel
dispensing pumps will reect the reduction
in sulfur to include Ultra Low Sulfur Diesel
(ULSD) and Low Sulfur Diesel (LSD). ULSD
fuel contains a maximum sulfur content of 15
ppm (parts per million) while LSD fuel contains
a maximum sulfur content of 500 ppm. 2007 and
later model year engines and emission systems
are designed to use ULSD fuel. Refer to the
OEM engine manual for which type of fuel is
acceptable for use.
WARNING
Use of LSD fuel in ULSD engines will
damage emission control systems and is
subject to fine.
CAUTION
Engines designed for ULSD fuel require
specially formulated motor oil classified
by the API (American Petroleum
Institute) as category CJ-4.
NOTE
Some states (including California) have
prohibited the sale of Low Sulfur Diesel.
Biodiesel: Biodiesel is a synthetic fuel made
from plant oil or recycled cooking oil. Biodiesel
is often sold as a biodiesel/petrodiesel blend
with an alphanumeric designation that indicates
biodiesel content. For example: B5 is 5%
biodiesel and 95% petrodiesel while B100 is
100% biodiesel. Due to variances in biodiesel,
its use is restricted by the engine manufacturer.
Refer to the OEM engine manual for acceptable
biodiesel tolerances.
Tips: Try to obtain fuel from sources that
are serviced often such as large truck service
facilities. The fuel supply is fresh and the
possibility of introducing contaminants or water
into the fuel system is reduced. If the engine
runs out of fuel, the fuel system will need to be
thoroughly primed before the engine will start
and run properly.
WARNING
DO NOT mix gasoline, alcohol or
gasohol with diesel fuel. This mixture
can cause an explosion.
NOTE
Due to the precise tolerances of diesel
injection systems, it is extremely
important that fuel be kept clean and
free of dirt or water. Dirt or water in the
system can cause severe damage to both
the fuel pump and the fuel injectors.
Fuel additives for lubricity are not
recommended. There are numerous
diesel fuel additives to help remove
moisture from fuel, prevent microbe
growth and to prevent gelling during
cold weather. Before adding any type
of fuel additive or extender, consult the
Manufacturer’s Owner’s Manual.
Fuel Tank
The diesel fuel tank is made of aluminum.
Pick-up and return lines are placed at opposite
ends of the tank to inhibit fuel aeration. The
engine pickup tube is cut at a 45° angle to allow
optimum ow to the engine. The generator
intake tube is set to approximately ¼ of a tank.
This will prevent depleting the fuel supply while
dry camping.
