Engine oil Blackstone lab report at 193,000 miles
Quote from the report:
"Your first report from your BMW [report was at 150,000 miles) was nice, but we're seeing even better results for your second sample from the engine. This was a similar oil change interval you got reductions in both aluminum and iron, which is great.
The other metals are quite steady. The oil is in fine physical condition and came out ofthe engine showing a correct viscosity and no measurable contamination from things like fuel, dirt, or coolant. Oil filtration is getting the job done, as seen by the 0.3% insolubles.
Looks like a solid engine as
you come up on 200,000 miles. Keep it up!"
