Lots of bad going on in this test. Doesn't indicate what oil you are using and there are a lot of very strong opinions, so suggest you read some oil threads to find one that suits your driving and climate. Now while 5k miles is a good interval with a quality synthetic, 1.5 years is obviously way too long. Your viscosity numbers should be in the 70 and 13 range with flash point closer to 400. Your oil has obviously broken down some time ago and was not protecting vital engine parts due to loss of vis. This is probably a major contributor to wear especially those plastic chain rails that depend on an oil film for startup.
My recommendation would be to change oil then in about 1500 mi drop the oil filter and send in for analysis. Look closely at flash point to rule out or confirm a leaky injector.
