How to Procedures 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. 76 All information subject to change without notice.
