Use of excess jet fuel in automotive diesel fuel affects lubricity additive response

Lockdowns resulting from the COVID-19 pandemic have had far reaching impacts across the transportation industry and, with the aviation sector being particularly hard hit, refiners are blending surplus jet fuel into automotive diesel fuel. Infineum’s Paul van Munster, Technical Lead, and Dean Clark, Lubricity Venture Manager, explore the impact this practice can have on the response of diesel fuels to lubricity improver additives and explain why refiners and blenders should reassess their additive treat rates and consider the merits of both monoacid and ester technologies.
