But, no, not any sign of lead build up. Perhaps without valves to catch the lead and with less access of oil to the combustion area perhaps? the rotary is less susceptible to the problem. However, having found that Mobile is being sued due to damaged aircraft engines from folks who used their aviation synthetic, I may have to reconsider. Ed
