A dry sump tank isn't something you usually see on a prerunner, but a dry sump oiling system offers the same benefit to prerunners as it does to race trucks. Dry sump oiling systems carry more oil and provide superior lubrication compared to their wet-sump counterparts. A dry sump also allows an engine to make more horsepower because the crankshaft does not splash through the oil sitting in the pan. With a dry sump, the oil is stored in the tank instead.
