Does the AeroVee require AvGas or can I run Auto Fuel?
The AeroVee can run on either AvGas: (aviation gasoline 91/98 minimum grade conforming to ASTM D 910) or Auto Fuel (automotive gasoline with a posted (R+M)/2 of 90 or greater conforming with ASTM D 4814). We give instructions to set-up a different compression ratio for AvGas (8.0:1) vs. Auto Fuel (7.0:1). There are many customers flying Auto Fuel in the AeroVee quite successfully. As a factory, however, our preference is for 100LL AvGas. 100LL maximizes the overhaul period for your engine and maximizes the available power output from your engine. At 3.5 gph in cruise, we feel there is no good reason to not burn avgas in these engines unless it poses a logistical problem.
