SERIES 60 ON-HIGHWAY ENGINE OPERATOR'S GUIDE Figure 11 Engine Oil Consumption Guidelines NOTICE: Before adding lubricating oil, refer to How to Select Lubricating Oil in this guide. Change lubricating oil and filters at the intervals listed in Table 11 when using fuel with a sulfur content of less than 0.05 mass percent. When using fuel with a higher sulfur content, refer to When to Change Oil in this guide. If the oil level is constantly above normal and excess oil has not been added to the crankcase, consult with an authorized Detroit Diesel service outlet for the cause. Fuel or coolant dilution of lubricating oil can result in serious engine damage.
* Change both full-flow filters when lube oil is changed.
