I agree with most of that info, however I don't like running that lean an oil ratio. There are synthetics available designed to be run at 32:1 - that's still only 4 ounces to a gallon! These synthetics don't leave deposits at 32:1, and more oil will provide a better ring seal and more safety margin on a lean needle setting. More oil also ensures that the needle bearings get enough lubrication. There's no downside to running more oil of the right type, other than cost and cleanup on the plane. But, nearly all of the plane motor manufacturers recommend synthetic AFTER break-in with petroleum oil.
