I wonder if anyone here ever heard about premix fuel for rotary engines? I learned about this in this video last year. So basically Mazda did have a rotor housing lubricating system that was not that good. The guy in the video deleted that system and premixed the fuel with 2T oil to lube the housing. A quick check around sites confirmed that this was a method used to extend the life of the seals.

One guy in some forum said that while premixing is great, it does have its drawback that the ratio cannot change to accommodate different loads. Some said a more complex solution of separate reservoir with metered feed is the best way.

I wonder is anyone in Malaysia used either these methods before?
