Here is the recent oil change from my 2013 Toyota RAV4. This is my first extended oil change, having just come off of the ToyotaCare free maintenance not too long ago. I'm not sure where the elevated silicon came from, it still had the factory air filter in it (replaced after the oil change). The only thing I can figure is maybe the receptacle I put the oil in was contaminated. I couldn't find my Blackstone kit so I put the oil in a new mini Ball jar and let the heat of the oil dissipating seal the lid. We'll see how it trends. Filter was FU.
