I am a pilot and am familiar with aircraft oils. I read a thread that mentioned several oils as being best for premix, but I didnt see any mention of aircraft engine oil which is formulated for "low ash" for the same reasons that the rotary engine requires low ash. Has anyone tried them?

 

Not sure about aircraft oil but I did read this thread :

"Idemitsu" is suggested

Yeah, it's been mentioned before.
Search Rx8club aircraft oil premix.

 

Yes, no easy single link, but we have several pilots here that have discussed it I believe.


There is also this section in the new owner's guide written on premixes: https://www.rx8club.com/new-member-f...4/#post3664007

If you have some good information to add to that, let me know.
