This article outlines some steps Southeastern Michigan Transportation Authority (SEMTA) has taken to improve maintenance practices for its large diesel-powered buses and smaller gasoline-engine units. Working with a research and test contractor, SEMTA determined that it needed a diesel-engine oil with a specification somewhat higher than specified by its engine builders regarding both chemistry and physical properties. The smaller engines showed markedly different oil-life characteristics which were then compensated for in the preventive maintenance program. The oil monitoring program is seen as a vital part of preventive maintenance and cost control for transit operations. It must also generate a real correlation between the lubricant and the engine in which it is used.
