That's true, but I think using "rich vs. lean" for oil mix introduces a little confusion into the conversation. The terms "rich vs. lean" for fuel and air is the accepted terminology in the engine world. Perhaps we could use "more oil" vs. "less oil" instead of "rich" or "lean" when speaking of oil and avoid the confusion....but whatever- it ain't going to ruin my day if people ignore my friendly suggestion.
