• Chromates: Chromate additives are not approved. Chromate additives can form
chromium hydroxide, commonly called "green slime." This, in turn, can result in
engine damage due to poor heat transfer. Cooling systems operated with a
chromate-inhibited coolant must be chemically cleaned with specially formulate
cleaning agents available through authorized Detroit™ service outlets. Only use
Detroit™ approved cleaning agents.
• Phosphate Inhibitors: Phosphate has tendency to form deposits on surfaces
transferring high heat which ultimately affect cooling capabilities. Phosphate
deposits on water pump seals will result in coolant leakage across seal faces.
How to Select Fuel
How to Select Fuel
Refer to the Lubricating, Oil, Fuel & Filters (DDC-SVC-BRO-0001) manual for
the most up-to-date fuel selection information.
All DD Platform engines are designed to operate on Ultra-Low Sulfur Diesel
(ULSD) fuel. For optimal fuel system performance, Detroit Diesel recommends
Top Tier Diesel (see figure below).
Quality
Use only Ultra-Low Sulfur Diesel (ULSD) fuel (15 PPM sulfur content maximum),
based on ASTM Standard D 2622 test procedure. Using fuel other than ULSD will
damage the fuel and aftertreatment systems.
Fuel quality is an important factor in obtaining satisfactory engine performance,
long engine life, and acceptable exhaust emission levels. In general, fuels meeting
the properties of ASTM Standard D 975 (grades 1-D and 2-D) have provided
satisfactory performance.
The fuels used must be clean, completely distilled, stable, and non-corrosive.
