Hello, as you can see this is my first post on BITOG and this is the first UOA I have done on any of my vehicles and wanted to share the results. I have been learning a lot from this forum and was interested to find out what shape the engine was in. This is my wife's car which she has owned since '06 with 76k miles on the odo when it was purchased. Car has 172k miles on it now and after a few DIY maintenance jobs it's running great.
Blackstone's comments - This first sample from your Matrix looked great. Universal averages show typical wear levels for this type of Yamaha engine after ~4,400 miles, and after a shorter interval, your wear metals line up nicely. In fact, nothing in these findings looks out-of-line, so you obviously have one well-oiled machine here! No measurable contamination was found, and insolubles (oxidized solids in the oil cause by heat, use, and blow-by) are low at 0.1%. The TBN is strong at 4.5, so you should have no trouble going ~5,500 miles on the next fill. Keep up the good work!
