This if from a fellow MINI enthusiast, we would appreciate comments on the report.... Stock super charged version of the MINI Cooper.... This car is still on the original clutch, some indication of how it is driven.
Well I finally got around to changing my oil on my 03 Cooper S and just got back the results from Blackstone Labs. All in all it looks good to me, this interval was super long ~25,000 miles. Unfortunately I forgot to ask for the TBN option. Next time I suppose. So to refresh memories I have an 03 S with now over 250,000 miles and I have always changed my oil when the OBC indicates to, usually between 15,000 and 21,000 miles. I have had both the oil pan off (leaky gasket) and the valve cover off in the past and the inside of the motor has always appeared to be super clean.
