I believe you're right, Al.  I was at the same seminar, and I believe he is using the metering system on his engine.

He described some items with the Renesis system that made sense for the car installation (crossflow intake, if that's the correct term), but made little sense in an aircraft installation.  In an airplane, I expect the intake to be completely custom, and the intake tubeage configuration of the vehicle installation to be out of the picture entirely.  Aside from some port timing differences and the side-port exhaust, it's still a rotary, right?

Is everyone else really using 1 quart of oil every 5 hours?  

 

He is undoubtedly talking about his install, and using the oil metering system for tip seal lube. I just did a 30 hour oil change on my 20B.  I added 1 pint since the previous oil change, and it was still full.  I use ¾ oz 2-stroke oil per gallon mixed with the fuel for seal lube; so that’s about 7 quarts for that duration.  Meanwhile, in that many hours, I have saved about $600 using mogas vs 100LL.
