Low Temperature Rheology of Soot-Laden, Heavy-Duty Engine Oils Using the Scanning Brookfield Technique

The rheology and related low-temperature pumpability of engine oils used in modern heavy-duty diesel engines are markedly affected by the presence of high levels of soot. This paper presents results of studies of the rheological condition of highly soot-laden oils using two protocols of the Scanning Brookfield Technique as investigative tools.
