David Atkins should not be allowed to give seminars at Oshkosh.  If I had not discovered the multiple errors made on the engine I got from him early on; it would have failed long ago.

 

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.
