So I sent off my first UOA to blackstone today and Im awaiting to see how the M1 Ow40 fares... I think it should be just fine.
However, the scary part about my engine (2007 audi s4) is that the block is sleeved with Alusil (aluminum x 80% and silicon by 20 I think). Scored cylinder walls from wear on a alusil block are pretty much a done deal on that engine. Would a UOA show higher levels of aluminum/silicon if I had wall scoring in this engine?
