SERIES 60 ON-HIGHWAY ENGINE OPERATOR'S GUIDE These products should be accompanied by performance data supporting their merit. It is not the policy of Detroit Diesel Corporation to test, evaluate, approve or endorse such products. FIRE To avoid increased risk of a fuel fire, do not mix gasoline and diesel fuel. Prohibited Additives The following fuel additives are not allowed and MUST NOT be mixed with diesel fuel: Detroit Diesel Corporation will not be responsible for any detrimental effects it determines resulted from adding drained lubricating oil or gasoline to the diesel fuel. Used Lubricating Oil Detroit Diesel specifically prohibits the use of used lubricating oil in diesel fuel.
Used lubricating oil contains combustion acids and particulate materials which can severely erode fuel injector components, resulting in loss of power and increased exhaust emissions. In addition, the use of drained lubricating oil will increase maintenance requirements due to filter plugging and combustion deposits. How to Replace the Fuel Filters Filters are an integral part of the fuel system. Proper filter selection and maintenance are important to satisfactory engine operation and service life. Filters should be used to maintain a clean system, not to clean up a contaminated system. Refer to the Specifications section of this guide for proper filter selection.
Gasoline The addition of gasoline to diesel fuel will create a serious fire hazard. The presence of gasoline in diesel fuel will reduce fuel cetane number and increase combustion temperatures. Spin-on type primary and secondary fuel filters are used on Series 60 engines. The primary filter (marked “P”) or combination filter and fuel/water separator removes large impurities from the fuel. The secondary filter (marked removes the smaller particles. Tanks which contain a mixture of gasoline and diesel fuel should be drained and cleaned as soon as possible.
