Religiously had oil changed with same mechanic since purchase. Oil light kept coming on. Blowing through exhaust. Engine needed replaced. New GMAC manufactured engine installed and oil light came on again.. Brand new CATalytic needed replaced ! New engine and a replacement CAT?? With less than 69,000 miles. Never buying another GMAC
