There is a needle bearing on the bottom end of the rod and a bushing on the top end. We are continuing to do oil content testing for wear and longevity but for now we are sticking with the 20:1 recommendation. I expect we will be able to recommend either 25:1 or 32:1 in the future but as of right now we have no long term data to stand behind that.

This should help.
