Im due to pick my 150 CDTi Sport Hatch up on Nov 11th (ahem!!) and its the first time of owning a diesel Ive a few beginners questions.
I believe the service interval is 20000 miles?! seems a helluva long time between oil changes to me, what are peoples experiences of the engine performance/condition degrading a long with the oil? I know just coming from a Clio 182 that although it was recommended to change every 12000 the car went much much better changing to fully-synth and changing every 6000.
What kind of oil does the CDTi come with as standard and will there be any benefit changing to a more performance orientated oil? Is there such a thing as that kinda oil for diesels as there are for petrol engines?
