Glad to hear this about the non detergent oil. I had Valvoline change my oil to 10 w 30. Within less than 300 miles the oil is black black black. It looked really clean when I changed it. Would you all suggest taking 10w30 out and replacing it with 15w40? It had been sitting for 7 years, maybe all the gunk settled during that time.
