Interest of the military in developing multiseasonal, extended-drain crankcase lubricants for the diesel-powered tactical fleet is addressed. These lubricants offer potentially large savings in lubricant, logistics, and manpower costs, and they can greatly improve overall fleet readiness. Studies have been conducted to examine various lubricant formulations, and engine modifications have been explored to identify approaches to extended-drain intervals. Both conventional and synthetic lubricants are being evaluated for future tactical fleet application. In addition, mechanical engine modifications which reduce oil degradation rates are being studied. Initial results indicate the near-term feasibility of using multiseasonal, extended-drain crankcase oils in a wide range of military applications, but with a significant increase in lubricant cost. Conventional, multiviscosity lubricant products appear to require further development before their introduction in the Army's combat diesel fleet.
