Got 5 liters of fairly expensive fully synthetic
in my DCi, clearly full of very small soot particulates, do you think I can just change the filter and leave the
in? What chemical / physical properties are likely to change over time that will affect the important properties?
The 530d I had used FS and had 178,000 miles on the clock and honestly, the internals looked as good as new.
Diesels run cooler than Petrols and don't pull the RPM's so the
*should* be in great shape pretty much for ever I guess?
My old petrol S80 2.4 had fully synthetic Castrol
and looked as good as new when it was changed. In fact I got the Volvo dealer to keep it for me and its been doing my mower justice ever since - still nice and golden after 5 years!
