Hi Charlie,
 
It makes sense that this would = be the=20 case.  Assuming they are using non-syntechic 2 cycle oil the oil = carries=20 more BTU than the highly refined gasoline.  As you know higher = Octane=20 gasoline does not produce more power - it=92s the fact that higher = octane delays=20 the onset of detonation which permits higher compression which results = in more=20 power.  Higher octane gasoline has fewer BTU than lower octane - = all else=20 being the same.
 
A high octane fuel, such as liquefied = petroleum=20 gas (LPG), has a lower energy content = than lower=20 octane gasoline, resulting in an overall lower power = output at=20 the regular compression ratio of an engine run at on gasoline. However, = with an=20 engine tuned to the use of LPG (i.e. via = higher=20 compression ratios, such as 12:1 instead of 8:1), this lower power = output can be=20 overcome. This is because higher-octane fuels allow for a higher compression=20 ratio

BTW,=20 anyone know of an adapter block for remote-ing the oil filter on a = Renesis? None=20 of the ones I've found list the=20 Renesis.
