My wife had the oil changed about 3 weeks ago on her Nitro and we started having a slight "dry" start in the mornings, pretty much immediately(Damn Valvoline!!)...I checked the levels and added some Lucas oil additive. About 4-5 days ago the oil light started coming on intermittently while dinging and flashing, then staying on for a while. Fluid levels were still good so I changed the oil pressure sensor...To no avail~ Yesterday the oil light stayed on almost consistent all day, then started sounding dry, which I'm assuming oil pump? What's my next step/Any thoughts, suggestions? 2007 3.7L 4x4....Thanks in advance!
