I'm struggling to figure out why Aerodiesels are still struggling to gain traction. Having flown in both a Piper and Cessna diesels, they are superior to Avgas engines in every way, other than cost. However a price difference of 75c a lite is getting a little ridiculous. $2.25 for Avgas v $1.70 for jet A. Jet A is also much cheaper still that Avgas in the USA. Engines burning half the amount of fuel that's significantly cheaper than Avgas should be a no brainer.
Yes, the vibration damper has had issues but it seems to be fixed now, the engines themselves seem to be bulletproof. Is it a case of, we have always used avgas so that's how things should be. A classic paradigm. For the life of me I can't see why any company would want to operate infrastructure for Avgas, produce Avgas, when there is so little return. The entire industry needs to rationalise to a single fuel to survive. That fuel is Jet A and it is readily available.
