Blackstone Oil Analysis - 1st change per BMW recommended interval
Mileage: 17,900ish
Top Off: ~2qts The chances are your engine is okay but you couldn't tell it from the amount of metal we found in the oil. The problem with the oil change lights is they don't take into account that your engine needs to pass through wear-in and a few brief oil changes get the engine there until the routine oil changes. This oil is terribly abrasive with metals and silicon and it is abrading parts. The TBN was okay at 2.4 but the oil is thick into the 20W/50 range. Moisture was present but it probably isn't anti-freeze. Run two 2,000 mile oil changes to clean up the engine. Unit Avg / Universal Avg ALUMINUM 80 / 4 CHROMIUM 2 / 0 IRON 70 / 12 COPPER 38 / 7 LEAD 5 / 2 TIN 5 / 1 MOLYBDENUM 30 / 101 NICKEL 2 / 0 MANGANESE 44 / 1 SILVER 0 / 0 TITANIUM 0 / 0 POTASSIUM 4 / 1 BORON 17 / 54 SILICON 15 / 6 SODIUM 18 / 6 CALCIUM 1434 / 2634 MAGNESIUM 1023 / 105 PHOSPHORUS 817 / 826 ZINC 1023 / 997 BARIUM 0 / 0 SUS Viscosity @ 210°F 80.2 / should be: 54-61 cSt Viscosity @ 100 Cel 15.57 / 8.5 - 10.8 Flashpoint in °F 365 / 365 Fuel % TR / <2.0 Antifreeze % 0 / 0 Water % TR / 0 Insolubles % .4 / <.6 TBN 2.4 TAN ISO Code Enjoy.

I felt with soo much talk about oil changes and BMW's long intervals that it would be beneficial to offer a sample of oil that was changed in accordance with BMW. I'm leasing this car, but I felt $30 spent was "good for the BMW community".

It's a naturally aspirated car, too, not a turbo.
Scary. (Memo to self -- order case of oil filters.)

Change it every 5K or less if you want your engine to last. I am sure if you speak the the BMW engineers, they will tell you the same.
EPA wanted to see much less waste oil produced by all vehicle manufacures, that is why we continue to see the service interval go up with each vehicle model change. |

Mines at 8,5xx miles.. I've just been waiting for the car to tell me it needs one, I have been very hesitant about this.. thought I'm just trying to see what happens, after all. if my engine screws up, warranty better take care of it.

"problems" resulting from extended oil change intervals probably won't show themselves until you're over 100k miles. That's the thing w/preventative maintenance. Majority of the time the car will be sold by the time the original owner would gain the "benefits" of extra time and $$ maintaining the car.
