Just had a AB service 3k ago roughly 3wks ago tonight got service reminder come up telling me A25 in 3250 miles which is oil and filter+ Dust&pollen filter, inspect drive belt and replace engine coolant. Obviously i know how the SvRS works but why would the oil need changing after 6250 miles. I know majority of members do change at roughly 6k and i will be changing when doing filters but the service book says 12.5k for oil changes. Is the car clever enough to tell me the oil needs changing again??
