Do all rotary engines in aircraft application need oil added (by mix or

injection) to help preserve the apex seals? First, I thought it was only
turbo engines, but now it seems everyone is talking about it. I've never
seen any mention about the cost of 2-cycle oil when people are comparing
(costs) of rotaries to conventional engines.

Is Kerosene "oily" enough to provide sufficent apex seal lubrication in the
heavy fule versions of the Rotary? Do you know if the Wankel GmbH  LOCR
range still require two-stroke fuel be added?

They all do Mark. I don't think kerosene will work. I would not risk
ruining an engine to find out :-)
