Has anyone ever used zmax
 

Has anyone ever used zmax oil additives in there 8 or in any rx I was wondering the linkite in the additives I ha e used it in traditional engines and seen a drop in temp of 20 degrees in coolent temps and almost 50 degrees In oil temps seams like it would help in a rotary and it also keeps the metal clean so it would help reduce carbon buildup using it on an old jeep that was suffering from blow by carbon build up on the valves with in one tank of fuel with it in it cleaned the valves to almost new when I scoped it.

Be ware of such claims. Some improvement may occur but there is little out that that cools an engine better than pure water and nothing that will knock off 50 degrees on oil temps without increasing the thermal capacity of the system.
