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 gas (LPG), has a = lower energy content than lower octane=20 gasoline, resulting in an overall lower power output = at the=20 regular compression ratio of an engine run at on gasoline. However, = with an=20 engine tuned to the use of=20 LPG (i.e. via higher compression ratios, such as 12:1 instead of = 8:1),=20 this lower power output can be overcome. This is because higher-octane = fuels=20 allow for a higher compression ratio
