Diesel Fuel Quality Can Vary
Greatly From One Location To The Next
Fewer Details Posted On The Pump, Diesel Drivers Have Little
Indication Of The Fuel's Quality Or Performance.
Technical Product Manager,
I can't tell you
how many times I have stood at the #2 ultra-low-sulfur diesel
(ULSD) pump and wondered just what I am getting out of that
green-handled spout. This concern is heightened during seasonal
changes from warm to cold when all diesel drivers begin worrying
about fuel gelling. The regulations controlling what is posted
at the pump are very different for gasoline and diesel fuel.
When you pull up to a gasoline pump you at least know what
octane fuel you are buying. Diesel fuel is different, but
rest a little easier knowing there are federal regulations
controlling certain performance properties of the fuel - they
just don't have to post most of them at the pump.
Diesel fuel is
a refined product of crude oil. If you performed a diesel
fuel study and compared fuels across the country, you would
find substantial differences in performance; however, you
would also find that all fuel refineries meet a federally
regulated standard for a few key fuel properties. The first
is sulfur content. The maximum limit on sulfur content in
on-road diesel fuel was reduced in 2007 from 500 ppm to 15
ppm, in accordance with the Environmental Protection Agency's
Clean Air Highway Diesel rule mandating a 97 percent reduction
in the sulfur content of highway diesel fuel. The new ultra-low-sulfur
diesel allowed engines to be fitted with exhaust systems that
emit less particulate matter and nitrogen oxide. Unfortunately,
reduced sulfur in fuel results in increased wear in fuel systems
and injectors. Sulfur in fuel acts as a natural anti-wear
agent that protects fuel pumps and injectors from premature
failure, so the reduced sulfur content left a hole that needed
to be filled by lubricity additives.
requires diesel fuel to have a certain level of lubricity
out of the pump as measured by the high-frequency reciprocating
rig (HFRR), a widely used friction and wear-scar testing system. For the
HFRR test, the lower the number recorded (in microns), the more protection provided by the fuel. The maximum
wear scar permitted in the U.S. is 520 microns. With sulfur
all but gone from today's diesel fuel, refineries have
started adding lubricity additives to ULSD to make up for
lost wear protection.
The second key
property is cetane index. This is a measurement of diesel
fuel's combustion efficiency during ignition. The higher
the number, the more easily and completely the fuel combusts.
In the United States the minimum cetane value is 40. Fuel
with a cetane number greater than 52 rarely delivers a substantial
performance benefit in engines designed in the
U.S. Because cetane values vary from region to region and
cetane numbers aren't posted at the pumps, diesel operators
have no indication which stations offer higher cetane diesel.
If you get your hands on test data, optimum engine performance
is found with cetane values between 46 and 50.
Depending on your
winter driving conditions, the most important diesel fuel
property may be its cold flow or its resistance to gelling in cold temperatures. The cold
filter plugging point (CFPP) is used to determine the lowest temperature at which fuel will flow without plugging
the fuel filter. Refineries accommodate seasonal changes by making a winter blend in which they mix
the normal #2 ULSD with a percentage of #1 diesel (kerosene) and some
cold-flow additives. Refineries increase the percentage of
#1 diesel and cold-flow additives depending on region and
temperature throughout the winter months to combat potential
fuel-related cold-weather driving problems. There are no federally
mandated minimum CFPP values that refineries must target for cold temperatures; and, unfortunately, fuel stations
again do not have to post the cold-weather performance of the fuel at the pump.
AMSOIL has long
recognized this variation in diesel fuel properties and offers
several products that provide additional performance and security
for diesel engines. AMSOIL Diesel Concentrate (ADF) provides
both detergency to clean fuel injectors and the combustion
chamber, and a lubricity additive to help lubricate the
fuel pump and injectors to compensate for the lack of lubricity
in ULSD. AMSOIL Cetane Boost (ACB) increases the cetane index
for improved ignition performance and power. AMSOIL Cold Flow
Improver (ACF) helps reduce the cold filter plugging point
and protects engines from fuel starvation in cold winter conditions.
In times of extreme cold, or when the fuel you purchased won't
flow in cold conditions, AMSOIL Diesel Recovery Emergency
Fuel Treatment (DRC) quickly dissolves gelled fuel and thaws
frozen fuel lines and filters.
You can't guarantee
high-quality fuel at the pump, but you can guarantee AMSOIL
diesel fuel additives will make that fuel the best it can
be to keep your diesel-powered application running at peak
performance throughout the year. Published, AMSOIL Magazine
AMSOIL Signature Series
Synthetic Motor Oil

synthetic motor oils are formulated to surpass engine test
specifications, offering protection far greater than competing
motor oils for extended drain intervals. Most synthetic oil
manufacturers make no claim to extended drain intervals, deferring
to the maintenance schedule provided by the vehicle manufacturer.
With its unparalleled oil and warranty program, AMSOIL offers
consumers unprecedented protection and economics.
More than 20 years
ago, AMSOIL began using the NOACK volatility test as a comparison
tool and measurement of quality. Back then, nearly every oil
tested side-by-side with AMSOIL synthetic motor oils failed,
and those that passed barely squeaked by. Other oil companies
paid no attention to NOACK results until Ford Motor Company
made it a requirement for service fill oils, validating what
AMSOIL had said all along.
NOACK Volatility Test
Volatility Test determines the evaporation loss
of lubricants in high temperature service. The more
motor oils vaporize, the thicker and heavier they become,
contributing to poor circulation, reduced fuel economy
and increased oil consumption, wear and emissions. AMSOIL
Synthetic Motor Oil resists high temperature volatization
better than other motor oils. AMSOIL Synthetic Motor
Oil maintains peak fuel efficiency and reduces oil consumption
