Contaminated Fuel
Do not use fuel that has been contaminated. Generally, fuel contamination occurs as
the result of improper fuel handling. The most common types of contamination are
water, dirt, and microbial growth (black slime). The formation of varnishes and
gums resulting from poor stability or extended storage, or stale fuel, also affects
fuel quality. The best treatment for contamination is prevention; maintain a clean
storage system and choose a reputable fuel supplier.
Fuel Additives
The regular use of aftermarket fuel additives is not required or recommended due to
potential engine and aftertreatment damage. These additives increase operating
costs without providing benefit. The use of supplemental fuel additives does not
necessarily void the engine warranty. However, warranty and repair expenses
which are determined, by Detroit™ or its representative, to have resulted from a
fuel additive will not be covered by Detroit™ warranty.
Biodiesel Fuels
Detroit™ supports biodiesel as a renewable fuel. Biodiesel fuels are mono alkali
esters of long chain fatty acids commonly referred to as Fatty Acid Methyl Esters
(FAME) and are derived from renewable resources through a chemical process
called transesterification. Detroit™ approves the use of biodiesel fuel blends up to
5%.
How to Drain the Fuel Coalescer
How to Drain the Fuel Coalescer
Incorporated into the fuel filter module is a coalescer. The coalescer removes water
and/or sediment and is located in the lower portion of the fuel filter module (see
graphic below). Water in fuel can seriously affect engine performance and may
cause engine damage. A water-in-fuel (WIF) dash indicator will warn the driver
when trapped water needs to be drained.
