Since there is a North American standard relating
to wear scar, Griffith said most fuel additives
will provide some degree of lubricity improvement.
The question is, how much?
" The North American specification for wear
scar is much easier to meet than other regions,
such as Europe, " Griffith pointed out. " So, there
is still plenty of room to improve fuel lubricity.
This is where a fleet may
want to treat itself because
the fuel coming out of the
pump might not deliver the
highest performance in this
area. The fleet can take it
upon itself to add additional
additives to better protect
its equipment, especially if
the fleet plans on hanging
on to that equipment for a
long time. "
One other consideration
with fuel additives relates to
cold-temperature operation.
Additives containing coldflow,
anti-gel properties can
benefit any fleet operating in
cold environments, including
southern fleets driving into
northern markets.
Finally, fuel additives can
result in an important side
benefit: better aftertreatment
system performance. Cleanerburning
fuel results in cleaner
exhaust. According to Hot
Shot's Secret's Steinmetz,
adding cetane to a fuel additive
is one of the easiest
and most effective ways to
improve DPF regens.
Speaking of DPF regens,
there are other additive products
available that are specifically
designed to tackle this
challenge head-on.
For instance, Lucas Oil's
Diesel Deep Clean is marketed
as a particulate filter cleaner
and power booster thanks
to its ability to deep clean
the entire fuel and exhaust
system. According to the
company, particulate matter
can be reduced by up to 32%
when used correctly, helping
to improve regen efficiency.
Another example is
MotorKote's DEF Reducer.
This additive is designed to
enable the combustion fuel
catalyst to allow fuel to burn
cleaner and more efficiently.
That can result in less soot
and filter
contamination,
resulting in a cleaner DPF that
can last longer, which results
in less DEF consumption-
hence the product's name.
Gibbs said field data shows
that proper use of DEF Reducer can reduce regens
by up to 80%.
Rislone is working on an additive of its own that
relates directly to the DPF. " A lot of fleets are dealing
with more frequent regens and fault codes, " Parks
said. " The product we're working on is designed to
help reduce the number of regen cycles. "
If there is a fuel- or oil-related headache fleets
encounter, you can bet that additive formulators
are working on a solution. Every fleet has different
assets, applications, and expectations. Whether
or not a given fleet decides to buy in to the use of
additives is up to that individual fleet. Nowadays,
the decision can be motivated by not just packaging
sales sizzle, but science from the lab and
performance data from the field.
