I just Bought a 2000 Dakota QC 4x4 w/ 4.7L V8. It has 56,500 miles. I want to change the oil but dont know if i want to use 5w30 or 10w30. I'm from PA so it dont get below 0 Fareheit very often so im leaning towards 10w30. Is that what you would run??? I dont wanna go synthetic seeing as most of my money is in truck and insurance payments!
