R56 First oil change...
#127
Well, I looked at the results of the analysis on the factory-fill oil, when I still had the stock airbox and filter. That oil was in the crankcase for 12,500 miles, and had similar Total Acid, Total Base, and fuel dilution numbers. Not totally spent, but definitely near its end-of-life.
For that first analysis, Terry thought the fuel dilution might have been because of the engine break-in, but it's still there, even though the current oil wasn't put into the car until 12,500 miles. I really wish I could see analyses from other MINIs, just to see what the typical dilution percentages are on other peoples' cars.
As for the oil that Terry recommended, it's Biosyn 5W-30, by RLI (Renewable Lubricants, Incorporated). He actually recommended their 0W-30, but I ordered the 5W-30 by mistake. Terry said that their 5W-30 is fine as well, and if we get good numbers using it, there's no reason why I couldn't stick with it.

Thanks, and thanks for sharing the results of your report,

Here's a site that talks about oil analysis results and what the various numbers mean. It's very general, and is no substitute for having an experienced tribologist analyze the lab results, but it'll give you an idea of what they're looking for.

I just changed my oil at 1200. Cost me Ramp $35, 27mm socket $5, filter $8, drain pan $11, total $59. (son-in-law works at BMW so I the filter cheap and free Oil). It took 1 hour and I took my time!! I will be doing it at each 7500 miles.
Here's the deal. with all that i'm reading I'll do what make me feel good. Yeah it runs hot, turbo, I drive hard, how can you not? So I'll take care of Winston.
