Preservative/Break-in Lubricating Oil

Army vehicles require aggressive protection from rust and corrosion during long-term storage. MIL-PRF-21260 specifies a preservative/break-in oil to preserve a vehicle engine for an indefinite storage period, then drive it into service. MIL-PRF-2104 specifies a separate engine oil for in-service Army vehicles. The preservative nature of the MIL-PRF-21260 degrades quickly upon engine operation. Surfaces Research proposes to develop a top treat preservative additive package that will convert MIL-PRF-2104 diesel engine lubricants into MIL-PRF-21260 preservative/break-in lubricants. Significant Army logistics and maintenance cost savings will be achieved by enabling the ready conversion of MIL-PRF-2104 oil into MIL-PRF-21260 oil. Surfaces Research has identified and obtained the most promising additives for incorporation into the preservative top treat package. We are uniquely qualified to formulate successful top treat additive packages immediately upon program initiation. Our Phase I work will demonstrate that our new top-treated MIL-PRF-2104 oil achieves the difficult combination of both preservative and operational performance of MIL-PRF-21260. Phase I Option work will improve the stability and life of the preservative additives, so that top-treated engine oil retains preservative function during engine operation for an entire oil change interval. This will enable vehicle storage at any time without an oil change
