I have a nephew who is a full time college student and works part time. We had a recent family get together. I asked him if I could check the oil on his Hyundai Sonata because I know he does not do regular oil changes. I looked at the sticker in the window from Wal Mart and he is over 27,000 miles on PYB. It made me sick. He is only about a quart low. There is heavy varnish buildup as I looked down through the filler cap. Made me sick. My sister(his mother) gave him the car to help him out at college. Good kid just no mechanical sense.
What is a good oil to clean up this engine? PYB. Mobil 5000?
