Msecrets18 Posted June 5, 2019 Share Posted June 5, 2019 Hello. I just bought a 2006 pontiac g6. I find that at high rpm it has a knocking noise and the oil looks like its never been changed its so thin etc. Can dirty oil be the culprit or is this knocking mean my engine is shot?? Its a v6 with 125000 miles on it and is in beautiful condition otherwise. I cant afford a shop so what?/how can i check myself to diagnose this?? Thanks everyone.
