RING (Oil) 9S4867 - Caterpillar

Synthetic base oils are acceptable for use in Caterpillar engines and in Caterpillar machines IF these oils meet the performance requirements that are specified by Caterpillar for a particular compartment. Each compartment has specific lubrication specifications to ensure proper lubrication and life of the system.Synthetic base oils generally perform better than conventional oils in the following two areas:
Synthetic base oils have improved flow at low temperatures especially in arctic conditions.
Synthetic base oils have improved oxidation stability especially at high operating temperatures.Some synthetic base oils have performance characteristics that enhance the service life of the oil. However, Caterpillar does not recommend automatically extending the oil drain interval for any machine compartment for any type of oil, whether synthetic or non-synthetic.Oil drain intervals for Caterpillar diesel engines can only be adjusted after an oil analysis program that contains the following data:
Oil condition, oil contamination, and wear metal analysis (Caterpillar S O S Services Oil Analysis)
