Comment: Thanks for the note about your additives and maintenance schedule. We don't usually recommend additives because we don't think they do much, but we can't complain with your results: this Toyota looks great. Wear metals read very low, which is what we've come to expect from Toyota engines. The only thing that read out of line was silicon, but we highly doubt this is dirt. If it were, wear would be higher. The silicon is probably from sealers or it's in one of your additives. It's not a problem. The trace of fuel is harmless. Try 8,500 miles next. Nice engine!
This is my 1st oil analysis. I did 2 applications of Auto-Rx before using GC Syntec since this engine is known to be a sludger. Did a 60K maintenance at 67,551 which Toyota added Valvoline Premium 5W30. Will probably change it out around 3K and try PP for 8000 miles.
