Toyota engines tend to wear quite well and your 3.5L engine is no exception. Universal averages show typical metal readings after about 6,700 miles on the oil. You put 12,000 miles on this fill and wear still looks great. Impressive, even! There are no problems here - this engine is still going strong. No contamination was found that might be a concern, and the oil itself held up well. No fuel or moisture was found, and silicon and insolubles show normal air and oil filtration. Go ahead and to 15,000 miles next time. Iron will increase slightly, but all else should hold steady.
