Group 177 Specifications VOLVO ENGINES Note: It is not recommended to mix synthetic oils with petroleum based oils. For further information concerning component specifica- tions see service information in Group 1, “Oil and Filter Change Intervals for Volvo Components,” publication number 175–001, and appropriate vendor literature. Maximum change intervals are 40,000 km (25,000 miles) if using oil that meets the Volvo Drain Specification (VDS). If the oil does not meet the requirements accord- ing to VDS, change intervals should be 24,000 km (15,000 miles). Contact Volvo or a Volvo authorized dealer to obtain a list of approved VDS oils.
Shorter oil change intervals maybe required if the engine is operating in a dusty environment or if frequent stops and starts are made (see oil change interval below). Supplemental coolant additives are recommended for all Volvo cooling systems. Antifreeze alone does not provide sufficient corrosion protection for heavy duty diesel en- gines. If the fuel has a sulfur content exceeding 0.5% by weight, halve the indicated maximum mileage intervals. Oil filters should always be changed when changing oil.
CUMMINS ENGINES For further information concerning component specifica- tions see service information in Group 1, “Oil and Filter Change Intervals for Volvo Components,” publication number 175–001, and appropriate vendor literature. If engine is operating in ambient temperatures consis- tently below - 20 C (0 F) or above 40 C (100 F), perform maintenance at shorter intervals. Shorter inter- vals are also required if the engine is operating in a dusty environment or if frequent stops and starts are made. Oil filters should always be changed when changing oil. Supplemental coolant additives are recommended for all Cummins cooling systems.
