I've seen some guys on here or somewhere else say they pour some mineral oil in the cylinders after fogging their sleds and then pull the cord slowly a couple times to get it through the engine based on the premise that the synthetic oil they run doesn't coat the internals as well for the off season. Without getting into an oil debate, if you were going to do this, how much oil would you pour in? An ounce on each side? Any downsides to doing this?
