HOW-TO SECTION bring the level to the Full mark on the dipstick. and Filters (7SE270), available from authorized Detroit Diesel distributors. NOTICE: NOTE: Do not use fuel with sulfur content above 0.05 mass percent for Detroit Diesel EGR engines. If the engine oil level is constantly above normal and excess lube oil has not been added to the crankcase, consult with an authorized Detroit Diesel service outlet for the cause. Fuel or coolant dilution of lube oil can result in serious engine damage. Fuel Contamination 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 (“stale fuel”) also affects fuel quality. The best treatment for contamination is prevention by maintaining a clean storage system and choosing a reputable fuel supplier. How to Select Fuel Oil Detroit Diesel engines are designed to operate on most diesel fuels marketed today. Quality Fuel quality is an important factor in obtaining satisfactory engine performance, long engine life, and acceptable exhaust emission levels. Supplemental additives are not recommended due to potential injector system or engine damage. Our experience has been that such additives increase operating costs without providing benefit.
In general, fuels meeting the properties of ASTM designation D 975 (grades 1-D and 2-D) have provided satisfactory performance. The use of supplemental fuel additives does not necessarily void the engine warranty. However, repair expenses which result from fuel system or engine component malfunctions or damage attributed to their use will not be covered. The fuels used must be clean, completely distilled, stable, and non-corrosive. For more information regarding the significance of these properties and selection of the proper fuel, refer to publication, Engine Requirements – Lubricating Oil, Fuel 80 All information subject to change without notice.
