Viking 130 HP Engine

Fuel flow is variable with power setting and airplane type. 

Rest assured the direct injected Honda is superior to any traditional aircraft engine.  


"I noticed your updates about switching to the 130 engine but I have never seen anything about the efficiency of the engine.
As for mine, before with the 110 engine I could cruise at 105 mph and burn 5.0 gph but with the 130 engine I can cruise at 115 
and burn 4.8 gph.  Not a bad improvement."
