Off road diesel and the diesel for the newer trucks and cars are not the
same. The fuel at the pump maked "Highway Diesel #2" means that the sulfur
level is approved for highway use and catalytic converters. Diesel #2 is
heavier than #1. It also (usually) has lower Cetane and more heat energy per
gallon than #1. #2 will tend to form wax crystals and gel at temperatures
below 10 degrees F. Most winter fuels are a blend of #1 and #2, but when it
gets really cold add fuel conditioner to avoid clogging the fuel filter with
wax crystals
Off road fuel still has the sulfur which affects wear, deposits, and
particulate emissions. Diesel fuels contain varying amounts of various
sulfur compounds which increase oil acidity. Legislation has reduced the
sulfur content of highway fuel to 0.05% by weight. Off road fuel has an
average of 0.29% sulfur by weight.
fuels, DOT inspectors, and the perils of having dyed fuel in a tank. Here
are the high points:
Off road Diesel #2 and fuel oil # 2 differ only in the tax applied at the
time of sale. Both are dyed red.
Kerosene #1 and #2 are lighter than #1 and #2 diesel fuel. Most kerosene is
dyed red.
The old method of winter treatment using 1 gal of kerosene to 10 gal of
diesel can get a driver into trouble unless it is dispensed as clear
kerosene from a pump which charges road tax.
Any red dye in a tank of fuel is detectable by the sampler the DOT uses,
even when diluted by a large quantity of undyed fuel. As little as 1/2 qt of
ATF in a tank of fuel will be detected as untaxed fuel and can cause a major
headache for the driver.
In VA, fines for using dyed fuel (untaxed) begin at $1000and go up rapidly
from there. Road checks for untaxed fuel began in northern VA, and have now
spread throughout the state.
Q: What is the difference between #1 Diesel and K1 Kerosene?
K1 kerosene is a low-sulfur kerosene that is made for use in space heaters,
lamps, etc. - and not for use in vehicles or generators. It is also not
taxed so would be illegal to use in "on-road" vehicles.
Lower lubricity is likely as the viscosity decreases. While this may not
cause catastrophic instant damage, it could cause long-term wear of pumps,
etc. Four semi-annual surveys for years 1990-1992 showed national averages
as such for viscosity (represented in milliPascal-seconds (mPa .
s)(=centipoise) cSt)
Diesel # 1 1.33
Diesel # 2 3.20
Kerosene 1.63
Both Kerosene and Diesel # 1 are less dense than Diesel # 2 and will thus
have a slight reduction (~3%) in BTU per gallon. This would likely be
reflected in lower fuel economy.
