Yes, it is very strange, supposedly its an advancement in the oil? A likely storey.Northern_Mike wrote: Funny how the same motor can suddenly do 20k. Having said that, the oil never really gets dirty after 6, 000. Maybe 9,000 would be ok?
Its not so much the oil getting black with a petrol engine which worries me, its the mixture of fuel within the oil and so less lubrication and more acid.
Off French car topic for a mo ... I find it strange how the Audi A2 1.4TDi is supposed to go for 30K between services (yes, 30K!) and my VW with the same engine and same oil recommendation is to go for 10-12k. Hmm ...
Obviously, the longer the service interval the lower the costs to the owner ... or so they have us believe.
