Due to the higher boiling range of fatty acid methyl esters (FAME), higher fuel dilution in engine oil is to be observed for the FAME containing test fuel in a modern diesel engine with diesel particulate filter, using active diesel particulate filter regenerations realized by post-injection. By the substitution of FAME with hydrotreated vegetable oils (HVO) the fuel dilution can be reduced. An elevated FAME content can lead to potential performance losses of the low SAPS engine oils. Thereby an accelerated consumption of oil additives and a reduction of wear protection capabilities can be detected. This effect can be softened by the substitution of fatty acid methyl esters (FAME) with hydrotreated vegetable oils (HVO).
