yes - tiny drops of diesel fuel in the oil weaken engine lubrication, leading to premature engine wear, bearing damage, and potential turbo failure. This often happens because of incomplete DPF regenerations, especially with frequent short trips, general city driving etc which forces unburnt fuel into the crankcase.

Overtime, it'll make a massive difference to how the engine runs as in runs or not runs if it is left with oil diluted with diesel! 2002 4.6 Vogue SE - Alveston Red with Lightstone Leather
