B 1 Fuel Requirements<br />

The STEYR Marine Engines are designed for maximum fuel economy. To maintain optimum performance use<br />

diesel fuel according to CEC RF-03-A-84 or equivalent to meet this specification. When temperatures are below<br />

-7° C (20° F), use diesel fuels with additives for low temperature operation.<br />

How to Select Fuel Oil<br />

Fuel quality is an important factor in obtaining satisfactory engine performance, long engine life, and acceptable<br />

exhaust emission levels. Direct injected diesel engines are designed to operate on most diesel fuels marketed<br />

today. In general, fuels meeting the properties of CEC RF-03-A-84 have provided satisfactory performance.<br />

The ASTM D 975 specification, however, does not in itself adequately define the fuel characteristics needed for<br />

assurance of fuel quality. The properties listed in the following fuel oil selection chart have provided optimum engine<br />

performance.<br />
