Here is an answer by jpe61 that was flagged as low quality. I strongly considered rejecting the flag, given the number of upvotes, until I looked at the question body. When I recommended deletion, he said
@Abdullah this answer adresses the "What does "2-cycle oil" mean?" portion of the question. Other aspects of the Q are perfectly adressed by Federico's answer.
So the answer complements another answer, and answers (only) part of the question. So it is a useful answer, though not a complete one. What should happen to it?
