A turbo-charged, sump-lubricated internal combustion engine which is susceptible to contamination of lubricant with liquid fuel, is lubricated with a lubricant which contains an amount of an aminic antioxidant, optionally in the absence of a phenolic antioxidant, thereby reducing the deterioration of said lubricant and formation of turbo sludge.
Selon linvention, un moteur à combustion interne lubrifié par puisard, suralimenté par turbo, qui est sensible à la contamination du lubrifiant par le combustible liquide, est lubrifié par un lubrifiant qui contient une quantité d'un anti-oxydant aminique, facultativement en l'absence d'un anti-oxydant phénolique, permettant ainsi de réduire la détérioration dudit lubrifiant et la formation de la boue de turbo.
