I hope this is the forum to through this. I have a friend in California with a 2005 Dodge and was thinking of using the 2 Stroke Oil in his diesel. But he threw this question at me ... "With all the State of California smogs for and the fines they LOVE to through out, what has been the problems with using 2 stroke oil in the diesel ?"I'm in a non-smog county and don't know what to say. Actually I now don't care what the State of California wants, but he is my friend. Anyone in a smog testing area that can answer this ?
