    Blackstone Labs Used Engine Oil Analysis - Part 2...

    Did an oil change at 10,000km and sent another sample down to Blackstone Labs for review. Looks good but there's still a trace of sodium which could be due to regular water and just winter washer fluid i've used for meth injection in the past (this was there last time as well). I've sprayed a tiny bit of the same winter washer fluid this time around in the beginning but most has been distilled water and meth (80/20 mix) so we'll see what comes up next.

    For reference, here's a link to Part 1:

    Overall, engine wear looks good according to Blackstone, especially given that I've gone 2000km longer on the oil this time around.

    Not bad at all, but you've added 2 qts of oil or roughly 28% of total oil capacity. The thing to remember is that Blackstone Lab results tell you absolutely nothing about how the engine is wearing. It only tells you about how serviceable the oil is. Good serviceability of the oil does not necessarily mean that the engine is doing well, but there are high chances that it is since you are using BMW LL-01 approved oil.

    BTW, I don't mean to bring flash backs about the wild discussions we've seen between TurkeyBaster and TrackRat on e90. I am just reminding you that while the BL tests are good to have, they are not definitive of the engine condition.
    From all the things I've lost,
    I miss my mind the most!

    I understand. Its just an additional metric to have and know as time goes on. Nothing is ever for sure until your engine starts to idle like crap or make loud knocking noises (except when its valve lifter related) Click here to enlarge

    True true! Click here to enlarge The good thing is that you are paying attention to things. That is one of the important factors for long term reliability.

    Another thing about the added 2 liters, the metals didn't just evaporate...adding 2 liters to the car wouldn't change the report in terms of anything but TBN...all the metals from wear would still be in there with everything else...

    They'd still be there but they'd be diluted since the concentrations are changing and blackstone only reports in parts per million (which would change).

    How would the "metals" and minerals composition dilute? Not sure I agree there

    This one actually is the new one. Before this I ran Castrol Syntec 5w-30 for 80,000km without a single issue. Then it was Mobil1 0w-40 and had various issues with it. Now I've been using the OEM 5W-30 and its working really well. My car just seems to enjoy the stock oil.

    One other oil the engine seems to love is the new gold bottle Castrol Edge 5W-30. Its expensive, 14.99/liter up here, but it seems to work really well as well.
