No the silicon showing up in a spectrographic analysis is not going to be captured by the filter as the particle size is way too small. On the other hand it’s also not what’s going to cause any damage either.I appreciate this response. Clearly the silcon was not captured by the filter and if I listened to Lexus it would be in my oil for another 9000 miles (or listened to others at least anothet 2 to 4k miles) i am glad I flushed it out and start again with fresh. Also why I want to do another OC at 1500. Overkill, sure maybe, but why run high contaminations for thousands of miles if I can flush them out for $30 (plus an UOA) and 30 minutes of time.
As to being a nervous nellie I dont think thats the case. Overzealous is probably the best description. Just looking to take as best care of my purchase as possible. If spending a few hundred $ on accelerated OCs now saves me thousands down the line I guess its worth it. Problem is that we will never know given the variables.
I am pulling a lot of my thoughts on OCI from Lake's videos and I think with his credentials I trust what he has to say. And the UOA he presents shows the proof. To me he has nothing to gain from encouraging shorter OCIs but I do have somrthing to gain from short OCIs. I am honestly surprised with some of the responses on an oil forum of people that question why I change oil post break in and so often early on or why I even do a UOA on a brand new vehicle/engine. I appreciate the dialogue as we all gain from it but surprised to see so much of it.
Nothing that shows up in a UOA like this causes damage, the question here is where is it coming from. If it’s from a sealant then it is completely harmless. If it’s larger particles from an intake leak that are being pulverized then that’s a different story. On a new engine it’s nearly always from sealants.
