Hello Mr Paul Lamar. I want some information about oil property (and
also the oil already use ) for aircrat rotary engine. in google I do
not find something and in a website I see your newsletter. please
help me if you can Thank you Mahdi Barjasteh

For the oil sump we recommend Mobil 1 or Idemitsu rotary engine oil.
For the apex seals we recommend mixing one ounce of two cycle oil
with each gallon of gasoline.

4 liters is about one gallon US so 1 ounce liquid US is about 30 cc
in the French system :)

30/4 is 7.5 so 7.5 cc per liter will work fine.

     I'd say that an additional possibility exists of putting 1 cc of
    LiquiMoly (MoS2) for every liter of fuel, that's what the producers
   of this Molybdenum Di-sulphide say, and the attached chart from the
   book by E McGovern points to a reduced wear when leaded gasoline
  was employed, Lead acting as a solid lubricant, MoS2 is also a solid
  lubricant, and thus, same good results can be expected with MoS2 additives,
  LiquiMoly or Molykote, as those detected with the fortunately no longer
  existent leaded gasolines.
     Best regards.

I am not rich enough by a factor of 10 million to try a new apex seal lubrication.
I would have to be near unconscious to try something that dumb :)

2.5 million Mazda engines have been sold using oil to lube the apex seals.

IT IS NOT BROKE!!!!!!!! However YOU are free to try it. Let us know how it works.
