Oil was supposed to be changed at 38k, now your a 43k. At what mileage was your oil changed? If it was changed at like 35k and synthetic oil was used then your fine. If it was changed at 28k, stop driving that car and get the oil changed asap.

That’s an asinine comment, if he did 5000 miles of engine damage he should buy a lottery ticket.

You’ll be okay. I’ve seen and driven on far worse.
