Abstract: This invention relates to a lubricating oil composition comprising or resulting from the admixing of: a) 50 to 99 mass % of one or more base oils; b) 0.1 to 15 mass % of one or more functionalized olefin copolymer having an Mn of from 10,000 to 35,000 g/mol; c) 0.1 to 20 mass % of one or more detergents wherein the detergent comprises at least one calcium detergent having a TBN of more than 100 mg KOH/g; at least one calcium detergent having a TBN of 100 mg KOH/g or less; and at least one magnesium detergent, where the difference in the TBN's for the Ca detergents is at least 100 mg KOH/g; d) 0.01 to 40 mass % of one or more dispersants wherein the dispersants comprise at least one borated dispersant and at least one non borated dispersant; e) 0.01 to 20 of mass % sulfurized fatty acid ester; f) 0.01 to 5 mass % of one or more amine or phenol based antioxidants; and g) 0.001 to 15 mass % of molybdenum containing compound, where the lubricating oil composition has: 1) a sulfated ash content of 0.

Abstract: A transportable system and method for determining erodibility of a surface such as that of an earthen embankment. Select embodiments deploy an instrumented portable bottomless open channel test enclosure, either a manifold or an inlet to a flume, and sufficient piping and valves to provide a fluid flow over a surface of interest. Select embodiments use mounts, such as spikes, affixed to the bottom edges of the open channel to position the channel flush against the surface, thus reducing or preventing fluid leakage along the periphery. Select embodiments emulate a hydraulic open channel having smooth vertical sides as may be found in a civil engineering laboratory. Select embodiments incorporate an external pump, gauges for taking measurements while fluid flows through the channel, an inlet and an outlet and a re-cycling sub-system from the outlet to the inlet.
