It's coming up on 5k miles since my car was serviced and I want to carry out an interim oil service. Bought oil air and pollen filter from conlons in Limerick. My question is this I want to do the change myself and there won't be any record of this in the service log, I know when I purchase a car especially when it came to the M3 service history was top of my list. Would it be a negative if I come to resell it down the line?
