Message It looks like you have owned the car since 2011, have you kept up with the oil changes? Was the previous oil change extended as the blackstone lab tech indicated? The previous owner you're referring to, is that the owner from Texas? If so, 20W-50 in the Texas heat isn't a bad idea. Doubtful it had anything to do with your turbo failure. Oil analysis is much more useful when done over a longer period of time (multiple oil changes) to establish trends etc. You're looking at a VERY small window in terms of mileage to determine the condition of the engine, not a very good indicator IMO. The high wear metals for such a small amount of mileage is interesting, that's why I'm curious about the oil change history. What is the low oil level problem you are referring to? Did you let it run low?
