Adam T7, “.... on conventional auto boxes, oil condition is dependent upon driving conditions and age, not just mileage.“
Yes, that’s surely the point. It would be crazy to wait say 10 years for a oil change at 40k. Every day that oil is heating up to over 100C then cooling down to near freezing, well at this time of the year Up North, at least.
A tough life (for the oil, not living Up North!).
I don’t want to start another debate here but a thought just struck me that VW might just say 40k to keep fleet managers running costs for their DSG cars down?
