Hi Charlie,
 
It makes sense that this would be the case.  Assuming they are using non-syntechic 2 cycle oil the oil carries more BTU than the highly refined gasoline.  As you know higher Octane gasoline does not produce more power - it’s the fact that higher octane delays the onset of detonation which permits higher compression which results in more power.  Higher octane gasoline has fewer BTU than lower octane - all else being the same.
 
A high octane fuel, such as liquefied petroleum gas (LPG), has a lower energy content than lower octane gasoline, resulting in an overall lower power output at the regular compression ratio of an engine run at on gasoline. However, with an engine tuned to the use of LPG (i.e. via higher compression ratios, such as 12:1 instead of 8:1), this lower power output can be overcome. This is because higher-octane fuels allow for a higher compression ratio

Subject: [FlyRotary] Fwd: oil premix data; info request


While searching for an oil filter remote adapter, I came across some interesting reading about the Renesis & oil premix that I don't recall seeing discussed in the past. It's near the bottom of the article.

http://www.racingbeat.com/mazda/performance/rotary-tech-tips/oil-filters-mop.html

BTW, anyone know of an adapter block for remote-ing the oil filter on a Renesis? None of the ones I've found list the Renesis.
