Does anyone know how the 2 cycle oil in the diesel will effect an emissions test? Where I live they require an emissions test, so I was wondering if I might could use the oil and still pass the et or maybe even stop using it a week or two before getting the test.Also I am noticing that most automobile gas stations are selling the ULSD fuel. It may be somewhere in this forum, but what is this doing to my 2001 Dodge Cummins motor? Can/should I add the oil to this type fuel without issue?
